Abstract
OBJECTIVE: The aim of this study is to describe the results of 16 patients with posterior fossa hemangioblastoma, treated with microsurgical techniques.
METHOD: Between June 2005 and December 2015, 16 patients with posterior fossa hemangioblastoma were operated on, underwent microsurgical resection. The sex, age, imaging findings, symptoms, and postoperative results were analyzed.
RESULTS: Eleven patients were men and 5 were women. The average age of the patients was 44 years. The most common form was cystic with nodule (57%); in 31% of the cases the lesion was purely solid. One case (6%) showed a lesion purely cystic, and one case was solid-cystic (6%). The major presenting symptoms were headache and cerebellar syndrome (43%); in 25% of the cases the patients suffered intracranial hypertension syndrome. The total resection was achieved in all the cases; in one patient an embolization was performed before surgery. Regarding postoperative complications: two patients developed ataxia (improved after three months), 1 patient presented a CSF leak (improve with an external spinal drainage). In addition, one patient died because postoperative complications.
CONCLUSION: The major features in patients with posterior fossa hemangioblastoma are a cystic with nodule form, presenting symptoms of headache and cerebellar syndrome. The total resection is possible, with a low morbi-mortality rate.
