## TL;DR

A rare case of a ruptured vasa corona pseudoaneurysm causing subarachnoid hemorrhage is reported, with successful treatment through direct surgery.

## Contribution

Presents a rare case of vasa corona pseudoaneurysm rupture without associated vascular malformations, highlighting direct surgery as an effective treatment.

## Key findings

- A 51-year-old female had SAH due to a ruptured vasa corona pseudoaneurysm.
- Direct surgery led to recovery without vertebral artery or posterior inferior cerebellar artery anomalies.
- Previous cases involved endovascular treatment for anterior spinal artery dilatation.

## Abstract

Ruptured aneurysms or pseudoaneurysms associated with the vasa corona, in the absence of cerebral arteriovenous malformation or dural arteriovenous fistula, are extremely rare but should be recognized as a possible cause of subarachnoid hemorrhage (SAH). We report the case of a 51-year-old female who presented with SAH due to a ruptured vasa corona pseudoaneurysm, with no associated anatomical abnormalities involving the vertebral artery or the posterior inferior cerebellar artery. She recovered after direct surgery. In previous cases, anterior spinal artery dilatation due to posterior inferior cerebellar artery anomalies prompted endovascular treatment. A thorough assessment remains crucial, and direct surgery can be effective.
