## TL;DR

A rare case of a benign heart tumor in a young, asymptomatic patient was discovered during a routine heart scan.

## Contribution

This case report adds to the limited literature on cardiac hemangiomas in young individuals.

## Key findings

- The hemangioma was found incidentally during an echocardiographic examination.
- The patient showed no symptoms despite the presence of the tumor.

## Abstract

Cardiac hemangiomas are benign neoplasms of extremely rare occurrence and, in
most cases, asymptomatic, commonly detected incidentally during examinations
performed for other clinical indications. To confirm the diagnosis and prevent
potential complications, surgical excision followed by histopathological
analysis is recommended. In this case report, we describe a left ventricular
hemangioma incidentally identified during an echocardiographic examination.
