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

Abstract

Solid hemangioblastomas of cerebellum are extremely rare in children and may be misdiagnosed as other pediatric intracranial tumors. A 13-year-old girl presented with a 5-day history of cerebellar dysfunction without apparent inducement. A computed tomography scan revealed a well-defined solid isodense lesion in the inferior aspect of the cerebellar vermis with intense homogeneous enhancement. Magnetic resonance imaging demonstrated a well-circumscribed solidly enhancing mass with serpentine signal voids in the periphery. Histopathology revealed a hemangioblastoma after surgical excision. This case draws our attention to a differential diagnosis of hemangioblastomas in children when a solid tumor is found in the cerebellum with hypervascularity and intense enhancement.
