# Case from Ballarat Base Hospital, Victoria - Epididymal cavernous haemangioma mimicking testicular torsion

## TL;DR

A 15-year-old boy's testicular pain was caused by a rare epididymal cavernous haemangioma, mistaken for testicular torsion.

## Contribution

Reports a rare case of epididymal cavernous haemangioma mimicking testicular torsion in adolescents.

## Key findings

- Epididymal cavernous haemangioma can present with acute scrotal symptoms similar to testicular torsion.
- Intratesticular haemorrhage from the haemangioma can lead to testicular necrosis and loss.
- This condition is extremely rare and often misdiagnosed due to its similarity to other testicular pathologies.

## Abstract

Epididymal haemangioma represents a rare aetiology of paratesticular masses. Here, we report a case of a 15-year-old adolescent who presented with acute onset left testicular pain and swelling. The patient underwent urgent scrotal exploration, which revealed a necrotic left testis, leading to subsequent orchidectomy. Pathological examination revealed a diffusely haemorrhagic testis with irregular collection of dilated vessels throughout the epididymis, in keeping with a cavernous haemangioma. This case highlights epididymal cavernous haemangioma as a rare cause of acute scrotal symptoms mimicking torsion.

•Cavernous haemangiomas are vascular malformations where leakage is prone to occur.•There are very few reported cases of epididymal cavernous haemangioma.•The onset of symptoms can be acute or insidious, mimicking various testicular conditions.•Secondary intratesticular haemorrhage can significantly impair the viability of the testis.

Cavernous haemangiomas are vascular malformations where leakage is prone to occur.

There are very few reported cases of epididymal cavernous haemangioma.

The onset of symptoms can be acute or insidious, mimicking various testicular conditions.

Secondary intratesticular haemorrhage can significantly impair the viability of the testis.
