ABSTRACT

Hemangioblastomas are benign, highly vascular neoplasms of the central nervous system (CNS WHO grade 1), most commonly found in the cerebellum. Despite their low-grade classification, these tumors can recur following incomplete excision. We present the case of a 45-year-old female who had undergone two previous posterior fossa tumor resections (in 2008 and 2014) and re-presented in 2025 with recurrence. A repeat suboccipital craniotomy was performed, and the lesion, which appeared vascular and fibrous with dural attachment, was excised piecemeal with dural repair. Histopathological analysis confirmed recurrent hemangioblastoma (CNS WHO grade 1). This case highlights the surgical challenges, recurrence potential, and long-term follow-up considerations in re-operation in recurrent posterior fossa tumors.
