# Intracranial Dissemination of a Cervical Sarcoma in a Young Patient With a Ventriculoperitoneal Shunt: A Case Report

## TL;DR

A rare case of a cervical tumor spreading to the brain in a young child with a ventriculoperitoneal shunt is reported.

## Contribution

This case report highlights an exceptionally rare instance of tumor dissemination from the peritoneum to the brain via a ventriculoperitoneal shunt.

## Key findings

- A three-year-old patient with a ventriculoperitoneal shunt developed intracranial dissemination of a cervical sarcoma.
- The tumor spread was linked to the shunt's subcutaneous path and prior hydrocephalus treatment.
- Such reverse metastasis from peritoneal to intracranial sites is exceptionally rare.

## Abstract

Ventriculoperitoneal shunt (VPS) related metastization of intracranial tumors to the peritoneal cavity is an uncommon but a well-recognized complication. Ascending spread of tumors, located in the peritoneum or near the subcutaneous path of the VPS, is an exceptional rare event.

We present a very rare and complex case of intracranial dissemination of cervical tumor in a three-year-old young patient with a past medical history of hydrocephalus-related post-endovascular treatment of Galen vein aneurysm through a ventriculoperitoneal shunt catheter implanted when the patient was five months old.
