Spontaneous hemorrhage is rarely associated with hemangioblastomas. Intratumoral hemorrhage occurring in cerebellar hemangioblastomas is more rare. A 25-year-old man was admitted to our hospital with headache. We found a round cystic lesion with solid part in the right cerebellum. The lesion was resected. The final pathological diagnosis was hemangioblastomas. The radiological features of this ...

OBJECTIVE To determine whether various clinical factors are related to long-term outcomes of patients with sporadic cerebellar hemangioblastomas. METHODS Subjects included 36 patients (19 men and 17 women) who underwent resection of sporadic hemangioblastoma in the cerebellum. Age at surgery ranged from 17-79 years (mean, 49.7 years). The tumor size, which was defined as the largest diameter ...

BACKGROUND Antiangiogenic treatment has been explored in few patients with hemangioblastoma after failure of surgery and radiotherapy. CASE REPORT We present the first histopathological follow-up study of a bevacizumab-responsive hemangioblastoma that eventually progressed. For a period of 12 months, therapy with bevacizumab achieved a clinical response and radiological stabilization in a pat...

Hemangioblastoma (HB) of the central nervous system may occur sporadically or in association with von Hippel-Lindau (VHL) disease. Disseminated HB means malignant spread of the original primary HB without local recurrence at surgically resected site. It has been rarely reported previously, and rarer especially without VHL gene mutation. We report a case of disseminated HB without VHL disease. A...

Hemangioblastomas are benignWorld Health Organization (WHO) grade I tumors that have been classified under the category of other neoplasms related to the meninges in the fourth edition of WHO classification of the central nervous system (CNS) tumors with an uncertain origin.1 They account for 1.5 to 2.5% of all intracranial neoplasms and 7 to 12% of posterior fossa tumors in adults, with 85% oc...
