[Primary central nervous system lymphoma in an immunocompetent patient]

Primary cerebral lymphoma is a rare tumour usually seen in immunodepressed patients. The clinical manifestations depend on its localization. Imaging using both magnetic resonance imaging and CT scan leads to the diagnosis that is confirmed bythe histolopathologic exam. Several therapeutic strategies are adopted in this type of tumour associsating neurosurgery, chemotherapy and radiotherapy. A 29 -year- old immunocompetent patient presented to our service with a 2-month history of headaches, vomiting and decrease in the visual acuity. Clinical examination and radiological findings revealed the presence of a cerebral lymphoma localized in the thalamus. Primary cerebral lymphoma is a rare tumour but whatever is the therapeutic strategy used, the evolution is normally rapid and positive

Tuberculoma as expansive process of the cerebellopontine angle; A rare presentation

Central nervous system tubrculoma presenting as a solitary mass in an extrinsic location is rare. Many factors make the diagnosis difficult, necessitating a surgical procedure. A 24-year-old man complained of unstable gait, slurred speech and occipital headache. Examination revealed an alert individual with bilateral horizontal nystagmus, facial palsy in the left and gait ataxia. Radiological investigation showed a growing process in the left cerebellopontine angle. Partial removal of the lesion via a retromastoid sub-occipital craniotomy approach revealed tuberculoma. Antituberculous treatment led to complete resolution of symptoms. This report shows that a mass in the CP angle can closely mimic a tumour radiologically. Histophathological examination confirmed it to be tuberculoma. Awareness of this rare presentation of a solitary tuberculoma in the CP angle is emphasized
