# An Uncommon Coexistence of Dural and Intraventricular Meningiomas

## TL;DR

This paper reports a rare case of a patient with both dural and intraventricular meningiomas, highlighting the importance of MRI in diagnosis and treatment planning.

## Contribution

The paper presents a rare clinical case of coexisting dural and intraventricular meningiomas and emphasizes the role of MRI in their diagnosis.

## Key findings

- MRI identified two distinct supratentorial lesions in a patient with chronic headaches.
- Histopathological analysis confirmed both lesions as meningiomas.
- The case highlights the importance of advanced imaging for accurate diagnosis of complex brain tumors.

## Abstract

Meningiomas, originating from the meninges encasing the brain and spinal cord, are the most prevalent primary intracranial tumors, constituting around 40% of all such tumors. These tumors primarily manifest within the dura mater, the outermost meningeal layer, and occasionally in locations such as the ventricular system. However, the concurrent presence of dural and intraventricular meningiomas is exceedingly rare. It could be challenging to tell them apart from metastases. We present a case of a middle-aged female with chronic headaches, where magnetic resonance imaging (MRI) revealed two distinct supratentorial lesions, one dural and the other intraventricular. Surgical excision was successfully performed, and histopathological analysis confirmed the presence of meningiomas in both locations, and subsequent referral was made for comprehensive management, encompassing radiotherapy and chemotherapy. This case underscores the significance of advanced imaging modalities, particularly MRI, in diagnosing and assessing intricate brain tumors.
