RESUMO
The authors reports a case of malignant schwannoma of sciatic nerve. Clinically, this tumor was manifested by a progressive tumefaction of the leg, and moderate pain, without functional signs. The origin of the sciatic nerve has been suspected by computed tomography, because its location, the vascular contacts, and the lesion's extension. Biopsy leads to confirm the nerve tumor, and precised the histologic type: malignant schwannoma. Local, regional and general extension did not premise treatment.

We report a case of double primary amoebic brain abscess in a 22 year old man, with signs of intracranial hypertension and deficit. Computed tomography found two hypodense lesions, not suggestive of pyogenic abscesses. Aspiration of one of the two abscesses, revealed the organism, and the two abscesses regressed in response to medical treatment. The authors insist on the rarity of these abscesses, their gravity, and the difficulty of the diagnosis.
