Hemangioblastomas: achados clínicos, epidemiológicos e anatomopatológicos em 14 casos

We report the clinical, epidemiological and pathological findings of 14 patients with haemangioblastoma. Sixty-four percent occurred in males, with ages ranging from 16 to 60 years, with an average of 34,4 years. Most of the tumours were confined to the cerebellum (n=9). The most frequent symptoms were headache (n=7) and dizziness (n=7), with a mean duration of 70 days. Von Hippel-Lindau syndrome (vHL) was diagnosed in 3 patients. Eleven patients were submitted to total surgical removal and in 3 the tumour was partially ressected. A relapse rate of 28% in 3 years of follow-up was found. The patients with vHL showed recurrence in 66% of the cases. These findings corroborate those in current medical literature, showing an increased morbidity of this tumor when associated with vHL.
