Abstract

Background

The most common type of vascularized tumor located in the posterior incisural space in older patients is the falcotentorial meningioma. Solid hemangioblastomas are rarely found in this particular area of the brain. To the best of our knowledge, the case of only one patient harboring a hemangioblastoma not associated with Von Hippel-Lindau disease has been previously reported in the literature in this anatomic region. Regarding age presentation, it is rare for sporadic hemangioblastoma in any part of the brain to occur in older patients; only two cases have previously been reported, and neither were in this anatomical space. A solid hemangioblastoma represents a surgical challenge because of its high vascularization, very similar to an arteriovenous malformation, and it should be removed en bloc to prevent significant intraoperative bleeding.

Case presentation

We report here the case of a 63-year-old white male patient with a sporadic hemangioblastoma located in the posterior incisural space mimicking a tentorial meningioma. It was completely removed en bloc via an infratentorial supracerebellar approach with an excellent outcome.

Conclusions

A hemangioblastoma should be considered among the differential diagnosis of hypervascularized masses in the posterior incisural space, even in cases of solid tumors, in older patients, or in the absence of Von Hippel-Lindau disease. These tumors located in the posterior incisural space represent a challenge, and the infratentorial supracerebellar approach provides panoramic exposure to allow safe resection.
