# Pre-operative Embolization of a Cerebellar Hemangioblastoma Using Polyvinyl Alcohol (PVA) and Target Tetra 360 Detachable Coil

## TL;DR

A patient with a rare brain tumor underwent pre-surgery embolization using PVA and a detachable coil, leading to successful tumor removal and symptom resolution.

## Contribution

The study demonstrates the effectiveness of combining PVA and Target Tetra 360 coil for pre-operative embolization in hemangioblastoma treatment.

## Key findings

- Pre-operative embolization with PVA and Target Tetra 360 coil enabled complete tumor resection.
- The patient experienced immediate and sustained symptom resolution post-surgery.
- The approach is considered curative for hypervascular hemangioblastoma.

## Abstract

Due to its hypervascularity, hemangioblastoma, a rare primary central nervous system intracranial tumor, has been treated with pre-operative embolization prior to surgical resection. Here, we describe a case treated as such. A 37-year-old male presented with worsening chronic headache and right ear tinnitus was found to have a hypervascular, heterogeneous right cerebellar lesion suspicious for arteriovenous malformation or hemangioblastoma. He underwent polyvinyl alcohol (PVA) and Target Tetra 360 (Fremont, CA: Stryker Neurovascular) detachable coil embolization followed by complete tumor resection. Pathology was consistent with hemangioblastoma. He presented with complete resolution of his symptoms immediately post-operatively and at a two-week follow-up. Our case highlighted the importance of pre-operative embolization to help achieve complete tumor resection which is considered curative in the treatment of hypervascular hemangioblastoma. The Target Tetra 360 detachable coil embolization is another material that can be considered.
