RESUMEN
A 90 year old male presented with symptoms and signs of right lower cranial nerves palsy. A small mass was found on the right side at the back of his mouth. Light microscopy and histoimmunochemical studies of the biopsy of the mass showed an alveolar soft part sarcoma arising from the right myohyoid muscle. The unusual location and presentation of this rare tumor is discussed

Six patients with cerebral tuberculoma seen over a 2 year period are reported. Their clinical presentations, the result of investigations including radiological findings and their response to medical treatment are discussed and correlated with other reports in the literature. Eighty five% of the patients were above the age of 30 years. All patients had negative past history of tuberculosis and both chest x-ray and erythrocyte sedimentation rate were within normal limits. Five patients presented with symptoms and signs of space occupying lesions but none had papilloedema. Two patients showed paradoxical enlargement or development of new tuberculous lesions during antituberculous therapy. The diagnosis was established by brain magnetic resonance imaging in 3 patients, and was further confirmed by brain biopsy in the other 3. All patients received antituberculous treatment for 12 months, except one who continued medication for 2 years. Four patients normalized with medical treatment. Intracranial tuberculoma must be included in the differential diagnosis of a space occupying lesion. Magnetic resonance imaging is a sensitive, non-invasive method to diagnose cerebral tuberculoma. Paradoxical enlargement or development of new tuberculomas during antituberculous therapy is a documented phenomenon which can be overcome by continuation of antituberculous treatment. Twelve months of antituberculous treatment is considered to be adequate to resolve intracranial tuberculoma
