Résumé
A 17-year-old man who had repeated pneumonia and presented with intermittent apnoea was described clinically and pathologically. Neurological examination and computed axial tomography revealed a calcified mass over the lower brainstem. Neurological intervention was done with removal of the tumour and the pathological section showed the classical picture of germinoma. The patient was given irradiation treatment afterwards and he was weaned off the respirator within a week. Unfortunately, he died because of recurrent chest infection after a long hospital admission of 92 days. Reviewing the literature showed the rarity of the germinoma at the brainstem location.

The CT appearances in 87 patients with intraventricular mass lesion were analyzed in order to verify the characteristic finding. The pathological diagnoses included medulloblastoma in 27, astrocytoma in 16, craniopharyngioma in 15, ependymoma in 9, meningioma in 7, AVM in 4, choroid plexus papilloma and epidermoid cyst in 2 each. One each had teratoma, ependymal cyst, cysticercosis, cavernous hemangioma and hemangioblastoma. The histologic diagnosis could be suggested by the frequency, location, density, age and sex of the patients. The differential features of each diagnosis are discussed.

CT appearances of 13 patients diagnosed as having CNS lymphoma were reviewed. Eight patients were of primary type and 5 patients had secondary CNS involvement. In primary CNS lymphoma, the median age was 62.5 years. All except one were male. Solitary lesions were observed in 4 patients; multiple lesions in 3 patients and an infiltrative lesion in one. Characteristic CT finding was a hyper-or isodense mass with homogeneous enhancement in the gray matter and corpus callosum. In secondary CNS lymphoma, the median age was 30 years. Two had solitary lesions. Isodense lesions were found in 4 of 5 patients.
