[Paraganglioma of the latero-sellar area. Case report].

Paraganglioma of the sellar and latero-sellar area is extremely rare. We report a case of latero-sellar and suprasellar paraganglioma of a 58-year-old women which caused deterioration of visual acuity and left exophthalmia without endocrine dysfunction. Magnetic resonance imaging showed a large tumor in the sellar and parasellar area, which extended to the left cavernous sinus and infiltrated the left orbit, the ethmoid, the sphenoidal sinus and the left pterygomaxillary fossa. Surgery by transcranial, left frontotemporal approach, enabled subtotal removal. Definitive histologic examination revealed a paraganglioma with signs of anaplasis. We report our clinical findings and present a review of literature.

[Cerebellar primary germinoma. Case report].

Germinoma cell tumors account for 1% of all primary cerebral tumors. They occur in pineal and in supra-sellar regions, and rarely, in basal ganglia and thalami. Germinoma cell tumors originating in the posterior fossa are very rare. We report a case of primary germinoma found in the cerebellar hemisphere in a 45-year-old immunocompetent man presented with intracranial hypertension and cerebellar ataxia. The CT scan revealed a heterogeneous mass in the cerebellar right hemisphere with a cystic component. Intense and heterogeneous enhancement after contrast infusion was observed. Two other nodules were identified in the frontal and occipital lobe. The pineal region was normal. Total resection was performed. The histological finding were a germinoma. Extensive systemic examination indicated that the intracranial lesion had not metastasized from a primary extracranial tumor.
