A 4-year-old African American male was referred to the Pediatric Neurosurgery Service for evaluation of new onset seizures and worsening mental status. An MRI of the brain revealed a pineal region mass with diffuse leptomeningeal enhancement and compression of the basilar cisterns. A biopsy of the brain revealed histologic and immunophenotypic findings characteristic of ALK-1+ anaplastic large cell lymphoma (ALCL). ALCL rarely occurs in the central nervous system and poses a significant diagnostic challenge often leading to a delay in the initiation of appropriate treatment. We describe a case of a rapidly deteriorating clinical course in a child with central nervous system ALCL and review the current literature on ALCL occurring in the central nervous system.

    ABSTRACT: Anaplastic large cell lymphoma (ALCL) is a rare T-cell lymphoma composed of CD30-positive lymphoid cells. ALCL arising in the dura matter of the brain is even more infrequent, in which only one case has been reported worldwide so far. We report a case of a 30-year-old immunocompetent male with a dura-based mass, radiographically consistent with meningioma. However, the excised mass via a left parieto-occipital craniotomy was composed of large, pleomorphic lymphoid cells to be immunopositive for CD3, CD30, anaplastic lymphoma kinase protein-1 (ALK-1) and epithelial membrane antigen (EMA), and immunonegative for CD20, CD15 and CD68. Multiple ALK gene fusion signals in the ALK locus were detected by fluorescence in situ hybridization (FISH) analysis. The patient was treated with CHOP chemotherapy and intrathecal methotrexate along with brain radiation therapy, which resulted in a complete remission. In an analysis of 25 previously reported primary CNS ALCLs, ALK-1 positivity was shown to be prevalent in younger age, as ALCL occurs outside the brain. Patient less than 23 years, ALK-1 positivity and unifocal tumor may be associated with a better prognosis. However, sex, dural or leptomeningeal involvement, immune status, and tumor necrosis do not appear to have any influence on survival.

    • "According to a report in 2007, seven of 14 patients with primary CNS ALCL died; two of them had ALK(+)ALCL, three had ALK(-)ALCL and the remaining two did not go through the test for ALK positivity.5 Given the insufficient sample size to be statistically significant, prognosis of primary CNS ALK(+)ALCL compared to ALK(-)ALCL is inconclusive.5,9,11 In addition, there are no statistically significant data on prognosis of primary CNS ALCL compared to CNS lymphomas in general, but the mortality of the former seemed to be greater than that of the latter.5,17 "

    ABSTRACT: A 31-year-old Korean male presented with altered consciousness and severe headache. Brain MRI delineated focal leptomeningeal enhancement without any intracerebral lesions. Diagnosis was made based on a brain biopsy showing anaplastic large cell lymphoma (ALCL), immunohistochemical stains revealing positivity for anaplastic lymphoma kinase (ALK) and an absence of involvement in any other organs; specifically, the primary central nervous system ALK+ALCL. Complete remission was achieved following 5 cycles of systemic chemotherapy with a high dose of Methotrexate and a simultaneous 7 cycles of intrathecal triple chemotherapy. Diagnosis of primary leptomeningeal ALK+ALCL is challenging given its rarity and non-specific symptoms along with non-pathognomonic radiologic findings. We present the first case of primary leptomeningeal ALK-positive ALCL where the clinical course, pathologic characteristics and treatment modality are described as well as a review of literature.

    ABSTRACT: Objective Primary central nervous system lymphoma (PCNSL) is an extremely rare condition in childhood. We report the first case of PCNSL in a child in Iran. Clinical presentation A nine-year-old boy was referred to Mofid Hospital with the history of headache of four months and seizure of 2 months duration. Magnetic resonance imaging of the brain revealed a hyper-intense lesion in left fronto-parietal area with secondary satellite lesions. Biopsy of the brain mass was performed. Pathologic findings showed brain lymphoma and immunohistochemistry confirmed this diagnosis. The treatment started with intrathecal and systemic chemotherapy in combination with radiotherapy.
