CT and MRI Features of a Solid Hemangioblastoma of Cerebellar Vermis in a Child: A Case Report

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% occurring in the cerebellum, including the cerebellar hemispheres and the vermis. They may occur either in sporadic forms or in association with von Hippel–Lindau (VHL) syndrome, to which only 5 to 30% of all cerebellar hemangioblastomas are attributed.2 Most hemangioblastomas occur in young adults of 20 to 40 years of age. However, in children, these tumors are extremely rare, with an incidence of less than 1 per million and accounting for much less than 0.5% of all pediatric brain tumors.3 In this report, we present a rare case of a 13-year-old girl with solid hemangioblastoma in cerebellar vermis without VHL syndrome.
