The authors report a case of recurrent cystic craniopharyngioma managed with chemotherapy. The patient refused adamantly the alternative therapy methods, such as surgery and radiotherapy, initially offered. Eight courses of chemotherapy with vincristine (2 mg/M2, i.v.) on day 1,1,3-bis(2-chloroethyl)-1-nitrosourea (100 mg/M2, i.v.) on day 2, and procarbazine (50 mg, b.i.d., p.o.) on days 3 to 21 were administered at 6 week intervals. The effectiveness of this treatment modality has been evaluated by the unequivocal neurological improvement and by the decreases in size of the cyst using serial computerized tomography. Toxocities were mild and chiefly hematological.

The authors describe a case in which transcatheter embolization was used to treat a large arteriovenous malformation of the scalp (cirsoid aneurysm), with subsequent development of multiple aneurysms at the embolization sites. This previously unreported complication may have far reaching implications in treatment modality selection.

A meningioma demonstrating unusual anatomical and clinical manifestations is described. This intracranial tumor originated in the petrous region and extended into the neck, the patient remaining neurologically asymptomatic for nearly 2 years. The radiological features of this tumor as well as a review of the pertinent literature are presented.

A craniopharyngioma with two unusual manifestations, a dense capsular stain and occlusion of the internal carotid artery, is reported. Neither of these findings appear to have been reported previously. Explanations for these unusual phenomena are offered.
