Since the difficulty associated with surgical planning of craniosynostosis is mostly due to the inadequate possibilities for simulation of surgery, a new technique for constructing a precise reproduction of a patient's malformed skull has been developed.
CT scans of ten malformed skulls on a scale of 1:1 and with 1-mm slices have been used to recon...
The clinical evaluation of hindfoot pathologies can be difficult but in recent years has been improved due to contribution of diagnostic work-ups such as ultrasonography, bone scan radionuclide imaging, CT, tendon sheath-CT, arthro-CT and MRI. In this paper, we evaluated the incidence of hindfoot pathologies in a population of 1310 athletes practic...
Traction, mechanical compression and impingement of the sciatic nerve may occur in certain anatomopathological situations at the origin of the hamstrings on the ischial tuberosity. The nerve, in fact, passes through a crossway formed of the quadratus femoris, the gluteus maximus and the common tendon origin of the long head of the biceps femoris, t...
Background:
The use of vasoconstrictors (e.g. dihydroergotamine, indomethacin) for the treatment of increased intracranial pressure (ICP) secondary to brain trauma is controversial. In particular, it has been suggested that vasoconstrictors be employed only for intracranial hypertension secondary to hyperemia, when venous jugular bulb saturation (...
Just like the lung, the brain and the spinal cord are target organs for opportunistic infections and tumors in immunocompromised patients. HIV infections and AIDS-related conditions represent the most common cause of immunodeficiency: other causes are hemoproliferative disorders and organ transplantation, but especially long-term drug and radiation...
The growing interest in shoulder joint imaging comes from the ever-increasing demand for such an examination in orthopedics. Since more complete and detailed imaging of bone, capsuloligamentous and musculotendinous compartments is always needed, CT arthrography has necessarily become a widely used method. In this study, 282 patients were investigat...
Clinical and radiographic follow-up was done on a group of patients with atraumatic patellofemoral joint disorders who had been treated surgically by realignment of the extensor apparatus at the authors' institution from 1985 to 1989. The preoperative radiographic examination in the 65 patients treated (for a total of 74 realignments) evaluated the...
The present study describes a case of AIDS with asymptomatic intracranial focal lesions. The DDD-enhancement CT technique detected the lesions as inflammatory or neoplastic. A subsequent MR demonstrated the vascular nature of the intracranial findings. MR in the neuropathology of AIDS can be of primary importance in the detection of the intracrania...
The authors report on a case of conspicuous retroperitoneal haematoma with haemoperitoneum due to rupture of the lower pancreatico-duodenal vessels appearing at onset of an acute oedematous pancreatitis. After stressing the rarity of this event, the authors go on to discuss a number of aetiopathogenetic, diagnostic and therapeutic aspects.
The results are described of a retrospective multicentric CT/MR study of 141 neuro-AIDS patients (IV group CDC classification); 114 patients were drug addicted, 13 homosexual, 8 polytransfused, and 6 had other risk factors. The mean age was 29.6 years. The pathologic agent was identified in 47 cases by c.s. fluid examination, biopsy, autopsy or spe...
Vengono esposti i risultati di uno studio retrospettivo multicentrico di 52 pazienti, affetti da Neuro-AIDS, con lesioni TC encefaliche focali, di cui 24 a patogenesi nota, mediante esame del liquor, biopsia, autopsia e/o criterio ex iuvantibus (11 toxoplasmosi, 3 criptococcosi, 5 HIV, 4 Tbc, 1 Papovavirus). La sintomatologia neurologica era preval...
Results are reported of a multicenter analytic-statistical CT study on 128 postoperative lumbar herniated disk (HD) cases (50 at L4-L5, 64 at L5-S1, 2 at L3-L4, 12 multiple). CT was performed from 10 days to 204 months (47.7 months of mean) after surgery, in 51 patients without and in 77 with intravenous contrast medium (42 in bolus, 35 in perfusio...
The high incidence of cruciate ligament injuries as a result of acute knee trauma with hemarthrosis and abuse of diagnostic arthroscopies call for a suitable radiological imaging of the central pivot. Computed Arthrotomography (CAT) was used to examine the knee joint in 20 cases of clinically suspected chronic cruciate ligament injury. The images w...
The results of a retrospective study of 10 cases of lipomyelomeningocele (LMML) and 4 cases of spinal lipoma in reoperated LMML observed over a 4-year period are reported. Patient's age ranged from 4 months to 12 years; a slight female predominance was noted (8:6). All patients underwent myelography, followed by CT-myelography in 11. MRI was perfor...
Oto-palato-digital (OPD) or Tyabi syndrome is a familiar, X-linked bone dysplasia with intermediate expression, in females or autosomal dominant with more severe manifestations in males. In the past both the clinical features (flat face with sunken and broad nasal bridge, antimongoloid slant of palpebral fissures, palatoschysis, conductive deafness...
In acute subarachnoid hemorrhage a ruptured cerebral aneurysm can be detected by Computed Angiotomography (Angio-CT). In a hyperdense cistern by extravasal blood, a round low-density defect on plain CT which turns into high-density nodular mass with afferent and efferent arteries, is an important finding of ruptured aneurysm. The inverting-density...
Authors report a case of 58 year-old woman suffering from a "clepsydra" shaped dermoid tumor spreading from the middle cranial fossa to the left posterior cranial fossa. The diagnostic importance of computed cysternotomography and the minor diagnostic value of other techniques such as angiography and pneumoencephalography is emphasized. The clinica...
The role of neuroradiological examinations in the diagnosis and in the therapeutical indication of intracranial aneurysm are analyzed and discussed on the basis of a large review of the literature. Skull X-rays, Ct scan with and without intravenous contrast enhancement, magnetic resonance imaging and angiographic have different role and different t...
Two cases of posterior inferior cerebellar artery aneurysms are reported. The diagnosis was made by dynamic multiplanar computerized tomography and afterwards confirmed by angiography and surgery. The role of CT in the diagnosis and follow-up of subarachnoid hemorrhage is discussed. Intracranial posterior fossa aneurysms are nicely demonstrated and...
A case of transient stenosing ureteritis in a boy presenting with the clinical features of Henoch-Schoenlein purpura (diffuse articular swelling, petechiae, abdominal pain) complicated by macroscopic haematuria with blood clots is reported. On urography the right collecting system and the right ureter up to the distal lumbar portion were dilated ow...
The authors describe the CT findings in 57 patients suffering from various non-neoplastic disease of the larynx: chronic laryngitis, pseudotumor, paralysis, post-traumatic lesions, laryngocele, cyst. CT is usefull in evaluating site and extension of the disease, as well as its relations with the surrounding tissues. The densitometric evaluation and...
A systematic investigation was carried out on 93 patients suffering from laryngeal tumours who underwent computed tomography and xeroradiography. A comparison is made between CT, xerographic, clinical and endoscopic findings. The value is stressed of functional informations obtained from CT performed during quiet breathing and phonation. The outsta...
