# Cystic intracranial solitary fibrous tumor: a case report

## TL;DR

This case report describes a rare cystic intracranial solitary fibrous tumor in a 42-year-old man, highlighting its imaging and pathology features to aid in diagnosis.

## Contribution

The novelty lies in presenting a rare cystic variant of intracranial solitary fibrous tumor with detailed imaging and pathological findings.

## Key findings

- The tumor was initially misdiagnosed as hemangioblastoma but confirmed as ISFT post-surgery.
- MRI showed a multicompartmental cystic lesion with surrounding edema and ventricle compression.
- The case emphasizes the importance of accurate diagnosis for effective treatment planning.

## Abstract

Solitary fibrous tumor (SFT) is a rare spindle cell tumor originating from mesenchymal tissue, and even rarer when it occurs intracranially. This case report described a 42-year-old man who presented with headache and limb weakness for more than 10 days. Magnetic resonance imaging (MRI) showed a well-defined multicompartmental cystic space-occupying lesion in the left occipital region, with surrounding edema and a compressed left lateral ventricle, the mass growing across the cerebellar vermis, which was initially diagnosed as hemangioblastoma. Neurosurgery was utilized to successfully remove the mass, and intracranial solitary fibrous tumor (ISFT) was identified by postoperative pathological analysis. Here, this article describes the imaging manifestations and pathologic features of a case of cystic intracranial solitary fibrous tumor, aiming to improve the understanding and diagnosis of this disease in order to provide an accurate therapy plan.
