Résumé
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

A 65-year-old woman, harbouring Rosai-Dorfman disease confirmed by biopsy of orbital lesion, presented with a history of headaches. Cerebral computed tomography and magnetic resonance imaging revealed an enhancing left temporal convexity lesion mimicking meningioma, however histological examination was diagnostic of Rosai-Dorfman disease. Rosai-Dorfman disease confined to the intracranial is rare. Only 57 cases have been published. Optimal treatment has not been established but complete surgical resection alone seems effective and allows for histological distinction from meningioma
Résumé
The supratentorial localization of haemangioblatoma is rare. Authors report a case of a 34-yeal-old male with 3-month history of elevated intracranial pressure and visual activity reduction. Computed tomography and magnetic resonance imaging revealed a posterior parietal parasagittal cystic mass with mural nodule at its medical aspect enhanced by contrast. The mass was exposed and removed via interhemispheric approach
