  • Article: Cranial pachymeningitis of unknown origin: a study of seven cases.
    [show abstract] [hide abstract]
    ABSTRACT: We report seven patients with cranial pachymeningitis of unknown origin in whom the main clinical features were headaches, ataxia, and cranial nerve palsies. CSF showed inflammatory changes. CT and MRI showed thickening of the falx and of the tentorium. The clinical course was chronic. Four patients improved with prednisolone but became steroid-dependent: in two cases, radiotherapy had no lasting improvement and in one, azathioprine permitted a reduction of the corticosteroids. Five patients had biopsy of the tentorium cerebelli or of the temporal dura mater. In two cases, autopsy revealed extensive pachymeningitis without parenchymal changes. In all instances, microscopic examination of the dura mater showed a cellular infiltrate of polymorphic cells; there were no epithelioid granulomas. Review of the literature discloses seven similar cases. We discuss the relationship of these lesions with inflammatory meningeal masses, the focal pachymeningitis of the Tolosa-Hunt syndrome, and multifocal fibrosis.

  • Article: Neuropathology of the spinal cord in the acquired immunodeficiency syndrome.
    [show abstract] [hide abstract]
    ABSTRACT: The neuropathologic findings in the spinal cord were reviewed in 138 consecutive autopsies of patients with the acquired immunodeficiency syndrome. In all cases both the brain and spinal cord were examined by conventional histologic techniques, and in 63 cases immunohistochemistry was used to detect human immunodeficiency virus (HIV), Toxoplasma gondii, cytomegalovirus, and JC papovavirus antigens. The most common observation was a normal spinal cord (60%). Vacuolar myelopathy (VM) was observed in 23 (17%) cases. Human immunodeficiency virus myelitis was evident in 8% of cases. Human immunodeficiency virus myelitis was associated with HIV encephalitis in 65% of the cases. Opportunistic infections of the spinal cord were uncommon, consisting of cryptococcosis (five cases), cytomegalovirus (four cases), toxoplasmosis (one case), and progressive multifocal leukoencephalopathy (one case), and almost always were seen with cerebral and/or systemic infection by these agents. Malignant lymphoma rarely involved the spinal cord (four cases); all were B-cell lymphomas and were associated with cerebral and/or systemic lymphoma. Other abnormalities rarely observed were Wallerian degeneration of the corticospinal tracts or posterior columns (6%) and focal microinfarcts. Most cases of VM (78%) were not associated with HIV myelitis, and in the five patients with both VM and HIV myelitis, HIV-infected cells were not found in the regions affected by VM. In contrast, 65% of cases with VM were associated with HIV encephalitis. The pathogenesis of VM remains unknown; it is probably not due to direct infection by HIV.

  • Article: Lymphoma-induced polyradiculopathy in AIDS: two cases.
    [show abstract] [hide abstract]
    ABSTRACT: Progressive polyradiculopathy is a rare, well-documented complication of the acquired immunodeficiency syndrome in man. It has been commonly attributed to a cytomegalovirus (CMV) infection. We report two HIV-infected patients with clinical and electrophysiological features of a unique, subacute, progressive polyradiculopathy. Post-mortem examination in case 1 disclosed an infiltration of the leptomeninges, the lumbar spinal cord, and the anterior and posterior roots by a B-cell immunoblastic lymphoma. Immunochemistry for HIV1 and CMV was negative in the peripheral and the central nervous system. Case 2 showed bone-marrow involvement by a Burkitt type lymphoma. Specific chemotherapy was followed by both clinical improvement of the polyradiculopathy and complete remission on a second bone-marrow biopsy. These findings may indicate that a lymphoma must also be considered a possible cause of polyradiculopathy in AIDS.

  • Article: The prevalence of ulcerated plaques in the aortic arch in patients with stroke.
    [show abstract] [hide abstract]
    ABSTRACT: The cause of cerebral infarction is obscure in up to 40 percent of patients with this disorder who are studied prospectively. In this investigation, we determined the frequency of ulcerated plaques in the aortic arch and explored the part they may play in the formation of cerebral emboli. Using an autopsy data bank, we studied the prevalence of ulcerated plaques in the aortic arch in 500 consecutive patients with cerebrovascular and other neurologic diseases who were studied at autopsy. Ulcerated plaques were present in 26 percent of the 239 patients with cerebrovascular disease but in only 5 percent of the 261 patients with other neurologic diseases (P less than 0.001). After we controlled for age and heart weight, the adjusted rates were 16.9 percent and 5.1 percent, respectively (adjusted odds ratio, 4.0; 95 percent confidence interval, 2.1 to 7.8; P less than 0.001). Among the patients with cerebrovascular disease, the prevalence of ulcerated plaques in the aortic arch was 28 percent in the 183 patients with cerebral infarcts and 20 percent in the 56 patients with brain hemorrhage. The prevalence of ulcerated plaques was 61 percent among the 28 patients with no known cause of cerebral infarction, as compared with 22 percent among the 155 patients with a known cause of cerebral infarction (P less than 0.001). After adjustment for covariates, the prevalence was 57.8 percent among patients with no known cause of cerebral infarction and 20.2 percent among those with a known cause (adjusted odds ratio, 5.7; 95 percent confidence interval, 2.4 to 13.6; P less than 0.001). The presence of ulcerated plaques in the aortic arch was not correlated with the presence of extracranial internal-carotid artery stenosis, suggesting that these were two independent risk factors for stroke. Ulcerated plaques in the aortic arch may play a part in causing cerebral infarction, especially in patients in whom cerebral infarction has no known cause.

  • Article: Human immunodeficiency virus (HIV) leukoencephalopathy and the microcirculation.
    [show abstract] [hide abstract]
    ABSTRACT: We studied the brains of three patients with acquired immune deficiency syndrome (AIDS), all of whom developed subacutely progressive dementia unassociated with opportunistic infection or neoplasm in the central nervous system. Computed tomographic (CT) scans of the head revealed cortical atrophy, ventricular dilation, and diffuse hypodensity of the centrum semiovale. On microscopic examination, the cerebral and cerebellar white matter in all cases showed diffuse and focal, angiocentric regions of myelin pallor, focal vacuolization, and extensive gliosis. Variable axonal loss and axonal spheroids were evident. The microvasculature showed striking changes, including mural thickening, increased cellularity, and enlargement and pleomorphism of endothelial cells with variable numbers of macrophages and multinucleated giant cells (MNGC), which often contained hemosiderin pigment. Human immunodeficiency virus type 1 (HIV-1) antigens were identified immunocytochemically within perivascular macrophages and MNGC and in some microglial cells. We suggest that the morphologic abnormalities of the microcirculation may be associated with an alteration of the blood-brain barrier. The increased vascular permeability could contribute to damage and loss of the white matter including both myelin and axons, and result in subcortical cerebral atrophy. The HIV-1 infected cells present in relation to the microvasculature may play a role in mediating the vascular injury.

  • Article: Neuropathology of the acquired immunodeficiency syndrome.
    [show abstract] [hide abstract]
    ABSTRACT: This review attempts to assess critically the literature on the neuropathology of acquired immunodeficiency syndrome in light of our experience with 172 patients with acquired immunodeficiency syndrome who underwent extensive postmortem examinations of the central and peripheral nervous systems. The neuropathologic manifestations of the disease can be divided into three categories: (1) primary or putative/indirect effects of the human immunodeficiency virus, (2) opportunistic infections, and (3) neoplasms. We discuss the known etiologic agents and postulated pathogenetic mechanisms responsible for the broad range of neurologic diseases observed in patients with acquired immunodeficiency syndrome.

  • Article: The spectrum of changes on 20 nerve biopsies in patients with HIV infection.
    [show abstract] [hide abstract]
    ABSTRACT: Nerve and muscle biopsies were performed on 20 patients with HIV infection and peripheral neuropathy. Nine patients had distal symmetrical peripheral neuropathy (DSPN) (six ARC and three AIDS), six had inflammatory demyelinating polyneuropathy (IDP) (three ARC, one AIDS, and two otherwise asymptomatic patients), one had mononeuropathy multiplex (MM) (AIDS), 1 had mononeuropathy (ARC), one had meningoradiculitis (AIDS), and two had areflexia-associated lymphocytic meningitides (ARC), DSPN exhibited axonal degeneration in four of nine cases and was associated with segmental demyelination in five of nine cases. IDP exhibited segmental demyelination associated with axonal degeneration in four of six cases. Demyelination was more frequent in asymptomatic patients (2 of 2 cases) and in ARC (7 of 12 cases), whereas axonal degeneration was predominant in AIDS (6 of 6 cases). Mononuclear cell infiltration was seen in 1 of 2 asymptomatic patients and in 11 of 12 ARC patients but was exceptionally found in AIDS (1 of 6 cases). Involvement of the walls of small vessels, mostly venules ("subacute microvasculitis"), was found in 1 of 2 asymptomatic patients, in 8 of 12 ARC patients, and never in AIDS. The polyclonal mononuclear cell population was composed mainly of Leu 2 (T8) positive cells in seven cases of ARC. No virions were seen in electron microscopy. HIV was isolated in two cases from the CSF or the nerve biopsy.

  • Article: [Cerebellar infarction in the area of the posterior cerebellar artery. Clinicopathology of 28 cases].
    [show abstract] [hide abstract]
    ABSTRACT: We report a neuropathological study of cerebellar infarctions involving the territory of the posterior inferior cerebellar artery (PICA) in 28 cases. Fifteen cases involved the PICA territory only. In 13 cases infarctions in the anterior inferior cerebellar artery (AICA) territory and/or in the superior cerebellar artery (SCA) territory were also present. A thorough post-mortem study of the arterial supply of the brain from the heart up to the cerebellar arteries, including the cervical spine segment of the vertebral arteries was performed in 27 cases. The territory of the cerebellar infarcts has been ascertained. In 15/28 cases (54 percent), infarction involved the PICA territory only (17 infarcts). All of these cases had a benign outcome and death was due to another cause. Six of these were recent infarctions. None had evidence of swelling and tonsillar herniation. Infarcts were generally of small size and involved the entire PICA territory in only 2 cases. Most of these cases were unexpected discovered at autopsy. Cerebellar infarction in the territory of the medial branch of the PICA (9/17 infarcts) drew grossly a set square with a dorsal base and a ventral top headed for the IVth ventricle. Five out of these cases were associated with infarction in the dorsal and lateral medullary territories. Retrospective clinical study showed that they had been unnoticed or overshadowed by other neurological disorders (4 cases), or presented as Wallenberg's syndromes (4 cases), or as a pure vestibular syndrome (due to an infarction involving only the cerebellum) mimicking an acute labyrinthine disorder (1 case). Infarctions in the territory of the lateral branch of the PICA (5/17 infarcts) always occurred without medullary involvement. All of them were unexpectedly discovered at autopsy, and were unnoticed during the life (3 infarcts) or were overshadowed by other neurological disorders (2 infarcts). That was also the case in 2 cases of infarction in the whole PICA territory (3/17 infarcts). Thus infarctions strictly localized to the entire PICA territory only were rare. Thirteen/28 cases (46 p. 100) of infarction in the whole PICA territory were associated with infarction in the AICA and/or the SCA territories. This resulted from an association with other infarctions and not from an abnormally large territory of the PICA. Cerebellar swelling with brain stem compression and tonsillar herniation occurred 8/13 cases (62 p. 100). There were other massive median and paramedian brain stem infarctions involving midbrain, pons or medulla in 55 p. 100 of 13 cases.(ABSTRACT TRUNCATED AT 400 WORDS)

  • Article: [Pathologic study of the eye and central nervous system in 25 cases of AIDS].
    [show abstract] [hide abstract]
    ABSTRACT: We have reviewed the clinical and pathologic findings of 25 patients with the acquired immunodeficiency syndrome (AIDS) who had a complete post-mortem examination including a study of the nervous system and of one or both eyes. Cytomegalovirus (CMV) retinitis was the most frequent type of ocular infection observed fundoscopically (9 of 18 cases examined clinically). There were only 3 cases of CMV encephalitis amongst the 8 cases of CMV retinitis documented pathologically. Cerebral toxoplasmosis was found in 12 of the 25 cases and in only one of these could Toxoplasma gondii cysts be demonstrated in the optic nerve. Cotton wool spots were the most frequent lesion observed fundoscopically (10 of 18 cases examined clinically). In the 3 cases where they were observed microscopically they corresponded to cytoid bodies which represented axonal swellings within the nerve fiber layer. The pathogenesis of this lesion in patients with AIDS is not understood. Intraocular lymphoma was present in only one case.

  • Article: [Myelopathy, polymyositis and systemic manifestations associated with the HTLV-I virus].
    [show abstract] [hide abstract]
    ABSTRACT: A case of HTLV-I associated myelopathy in a 51 year-old Haitian woman is reported. MRI showed high signals in the cerebral white matter on T2-weighted images. There also was clinical and electrophysiological evidence of myositis, and a biopsy of the quadriceps muscle showed dense inflammatory infiltrates surrounding several small perimysial blood vessels. The virus was not demonstrated in the muscle. The presence of several systemic abnormalities (polyclonal gammapathy, circulating immune complexes, Sjögren's syndrome) and the vasculitis suggest an immunopathological mechanism for this HTLV-I associated myositis.

  • Article: [Neuropathology of human type 1 immunodeficiency virus infection].
    D Hénin, J J Hauw
    [show abstract] [hide abstract]
    ABSTRACT: The nervous system may be affected at any stage in the course of HIV-1 infection. Acute or subacute inflammatory demyelinating polyradiculoneuropathies occur often early and improve spontaneously. Distal symmetrical axonal, predominantly sensory, painful polyneuropathies occur in the late stages of the disease. Microvasculitis is frequent in the early neuropathies. Spastic and ataxic paraparesis associated with vacuolar myelopathy are rare and probably not related only to HIV-1. Aseptic lymphocytic meningitis may occur as the presenting or sole manifestation of HIV-1 infection. The more frequent subacute encephalitis, probably directly related to HIV-1, is late in the course of the disease. Microscopic changes are suggestive but non-specific (microglial nodules, multinucleated giant cells). According to some authors, HIV-1 infection of the central nervous system macrophages may be early and latent until associated pathologies (opportunistic infections, lymphoma) trigger the replication of HIV-1 by infected macrophages.

  • Article: [2 cases of Waldenstrom's disease associated with a glioblastoma].
    [show abstract] [hide abstract]
    ABSTRACT: The association of Waldenström disease and glioblastoma was observed in two patients. Both diseases were diagnosed almost simultaneously. In the first patient the diagnosis of glioblastoma was made on cerebral biopsy. In the second case, the diagnosis was confirmed at autopsy. The association of Waldenström's disease and glioblastoma is rare but it does not seem to be coincidental. The physiopathological problems related to this coexistence are discussed.

    ABSTRACT: Post-mortem study of every patient who died from AIDS in Pitié-Salpêtrire Hospital from June 1984 to November 1985 was performed without regard to the presence of neurological signs and symptoms. Autopsy were performed in 31/48 cases. Patients had been hospitalized in the Departments of Parasitology-Infectious Disease (24 cases) Internal Medicine (4 cases) and Neurology (3 cases). In every case, formalin-fixed material from the brain and the spinal cord were embedded in paraffin (20 samples), stained with hematoxylin-eosin, PAS, Alcian blue, Giemsa, Grocott and Ziehl techniques and Bodian's silver impregnation along with Luxol fast blue, and, in celloïdin (8 samples), stained with hematoxylin-eosin and Loyez' impregnation. There were 30 men (27 caucasian, 1 egyptian, 1 haïtian, 1 senegalese) and one woman (congolese). Twenty eight (28) patients were homosexuals. AIDS was transfusion-associated in two cases. Neurologic complications revealed the disease in 2 cases. Eighteen (18) patients had neurological signs or symptoms before death. Age range at death was 22-58 (mean 38). Brain weight in AIDS (from 1150 gms to 1750 gms-mean 1428 gms) was not statistically different from the mean weight of 100 male patients in the same age range autopsied in the same laboratory during the identical period (mean 1427 gms, standard deviation: 23). Microscopic abnormalities were present in every brain examined. These included non-Hodgkin lymphoma (3 cases), opportunistic infections (21 cases: 13 toxoplasmosis, 4 cytomegalovirus encephalitis, 3 cryptococcal meningitis, 1 infection by mycobacterium avium-intracellulare), and subacute encephalitis (17 cases, 9 isolated, 8 associated with other disorders). The characteristic changes consisted of lympho-monocytic focal infiltrates (so-called microglial nodules) and mild lympho-monocytic perivascular cuffs in 10 cases. Typical giant cells were seen only in one case. Mild demyelinating changes were also seen in only one case. No spinal cord spongiosis, nor Progressive Multifocal Leukoencephalopathy was found. HIV localization was performed on frozen sections utilizing in situ hybridization techniques (2 cases) and immunohistologic techniques (5 cases). HIV, RNA and proteins, was detected in 2 cases with subacute encephalitis. Infected cells were labeled with macrophage markers, and rarely with T4 lymphocyte markers. Infected astrocytes (identified by anti-GFAP serum) or neurons (identified by anti-NSE serum) were never observed. No giant cells were seen in these two cases.
