Background: Hemangioblastomas are rare, benign, vascular neoplasm. According to the World Health Organization classification of tumors of the nervous system, hemangioblastomas are classified as meningeal tumors of uncertain origin and are Grade I neoplasm. Hemangioblastomas arise either in the setting of von Hippel-Lindau (vHL) disease or more often as solitary sporadic lesions. They account for 1-3% of primary central nervous system (CNS) tumors. The most common location is the cerebellum followed by spinal cord. Supratentorial lesions are rare. Aims: The aim was to study the prevalence of hemangioblastoma. Materials and Methods: A retrospective observational study of 7 years duration was carried out in the department of pathology of a tertiary referral center. The sample received was processed by standard formalin fixing, paraffin embedding method. Serial sections and special stains were studied as and when required. Results: During the period of 7 years, we reported total 679 cases of primary CNS tumors, of which 11 (1.62%) cases were of hemangioblastoma. Ten of them were intracranial, and one was spinal. There were seven male and four female patients that clearly indicate male preponderance. Conclusions: In our study, prevalence of hemangioblastoma was 1.62% (11 cases) out of 679 primary CNS tumors, which is low as per literature. There was a male predominance with male:female ratio 2:1. Cerebellum was the most frequent site (81.8%). No association with vHL disease was noted. |
