# Exceptional localization of intramuscular hemangioma: Insights from a 66-year-old case

## TL;DR

A rare case of a benign muscle tumor in a 66-year-old patient is reported, showing how it developed over ten years in the calf muscle.

## Contribution

The novelty lies in the detailed clinical and diagnostic description of an intramuscular hemangioma with a long progression timeline.

## Key findings

- The tumor originated from the flexor hallucis longus muscle and caused progressive swelling and pain.
- MRI was used to accurately characterize the lesion, supporting the diagnosis of intramuscular hemangioma.
- Surgical resection is highlighted as the recommended treatment for such cases.

## Abstract

Intramuscular hemangiomas are rare benign vascular tumors, accounting for less than 1% of all hemangiomas. They often present with subtle symptoms that gradually worsen over time. Magnetic resonance imaging (MRI) is the gold standard for diagnosis, providing detailed lesion characterization. Surgical resection remains the preferred treatment. We report the case of a 66-year-old patient with a painful swelling in the calf that had progressively increased in size over ten years, originating from the flexor hallucis longus muscle.
