A Large Solitary Hemangioblastoma of the Lateral Ventricles: A Case Report and Literature Review

Hemangioblastoma (HB) in the supratentorial region of the brain is rare and only a few cases are reported on intraventricular HB. HB of the lateral ventricles is even rarer. We present a case of a 30-year-old man with generalized tonic clonic seizures. The brain computed tomography showed a 5.5 cm heterogeneous mass extending into both lateral ventricles with partial enhancement. Based on the size and imaging features, we present the fourth documented case of a large solitary intraventricular HB. Our approach to this unique case and some treatment complexities are also described. Considering the rarity of the case and the patient’s imaging features, the present study provides a better understanding of HB and recommends HB to be considered in the differential diagnosis of masses in the lateral ventricles. In addition, some preventable pitfalls in the treatment of such complex cases are described.
