# A Rare Case of Sphenoid Sinus Hemangioma With Intrasellar and Cavernous Sinus Extension

## TL;DR

This paper presents a rare case of a sphenoid sinus hemangioma that extended into critical brain areas, highlighting the challenges in diagnosing such tumors.

## Contribution

The novelty lies in reporting a rare case with atypical features and emphasizing the importance of considering hemangiomas in differential diagnoses.

## Key findings

- The patient's symptoms and imaging mimicked an aggressive tumor but were confirmed as a hemangioma via histopathology.
- The case underscores the need for careful diagnosis to differentiate hemangiomas from more aggressive pathologies.
- High vascularity and bone remodeling on imaging were key features in this case.

## Abstract

Sphenoid sinus hemangiomas are uncommon and pose significant diagnostic challenges due to their rarity and the complex symptoms associated with their critical anatomical location. This report discusses a woman in her 40s who presented with worsening headaches, diplopia, and a sensation of pressure behind her eyes. Diagnostic imaging revealed a lobulated mass in the sphenoid sinus extending into the cavernous sinus and sella, initially mimicking an aggressive neoplastic pathology. However, histopathological examination following endovascular embolization and partial surgical resection confirmed the diagnosis of a cavernous hemangioma. This case highlights the importance of considering hemangiomas in the differential diagnosis of sphenoid sinus masses, especially when patients present with atypical symptoms and imaging shows features such as high vascularity and bone remodeling. The findings emphasize the need for careful diagnostic and therapeutic approaches to effectively manage such cases and differentiate them from more aggressive pathologies.
