# Diffuse subarachnoid hemorrhage following ventriculo-peritoneal shunt insertion for acute obstructive hydrocephalus from large glomus jugulare tumor: case report

## TL;DR

A rare case of subarachnoid hemorrhage occurred after a shunt was placed to treat hydrocephalus caused by a large glomus jugulare tumor.

## Contribution

This is the first reported case of subarachnoid hemorrhage following a shunt for hydrocephalus caused by a glomus jugulare tumor.

## Key findings

- Subarachnoid hemorrhage is an extremely rare complication of ventriculoperitoneal shunt insertion in patients with glomus jugulare tumors.
- Preoperative CT angiography is recommended to detect vascular malformations in highly vascularized tumors.

## Abstract

Glomus jugulare tumors (GJTs) are rare intra-cranial tumors. Commonly, these lesions present with cranial nerve palsies, headaches, and hydrocephalus. Rarely, GJTs present with spontaneous subarachnoid hemorrhage. However, there has never been a report of diffuse subarachnoid hemorrhage following ventriculoperitoneal shunt insertion in a patient who developed hydrocephalus secondary to any brain tumor in general or glomus jugulare tumors in particular.

The authors presented an extremely rare complication of diffuse subarachnoid hemorrhage following the insertion of a ventriculoperitoneal shunt (VPS) in a 61-year-old female patient who was diagnosed to have both clinical and radiologic features of acute obstructive hydrocephalus secondary to a highly vascular huge glomus jugulare tumor.

Subarachnoid hemorrhage following ventriculoperitoneal shunt insertion for hydrocephalus caused by a mass lesion is an extremely rare complication. Preoperative CT angiography should be strongly considered to look for the associated vascular malformations in extremely vascularized mass lesions. Given the not ubiquitous availability of all therapeutic options for GJTs, especially in low and middle income settings contributes for the poor outcome of GJTs and it fosters a global neurosurgery agenda.
