# Anterior tibial aneurysm involving the transition to the dorsalis pedis, a therapeutic challenge

## TL;DR

A rare case of a tibial artery aneurysm in a 53-year-old woman was successfully treated with coil embolization.

## Contribution

Presents a novel case of asymptomatic anterior tibial artery aneurysm treated successfully with coil embolization.

## Key findings

- Aneurysm was asymptomatic and detected incidentally during ultrasonography for plantar fasciitis.
- Treatment via coil embolization was effective with no complications.
- Highlights the challenge of diagnosing asymptomatic tibial artery aneurysms before rupture or thrombosis.

## Abstract

An aneurysm of the anterior tibial artery is always a challenge because it does not provoke symptoms and when a pulsating mass is detected, the aneurysm diameter is already enlarged and there is a greater likelihood of rupture or thrombosis. We report the case of a healthy, 53-year-old, female patient diagnosed with an aneurysm of the anterior tibial artery at the transition to the dorsalis pedis artery, which was identified during ultrasonography performed to investigate plantar fasciitis. The aneurysm was treated by coil embolization and there were no complications.

O aneurisma de artéria tibial anterior é sempre um desafio, pois não apresenta sintomas e, quando há a percepção de uma massa pulsátil, o aneurisma já apresenta diâmetro aumentado, com uma maior chance de romper ou de trombosar. Relatamos o caso de uma paciente do sexo feminino, 53 anos, hígida, que apresentou o diagnóstico de aneurisma na artéria tibial anterior na transição com a artéria dorsal do pé, sendo identificado a partir de ultrassonografia realizada para investigação de fascite plantar. O aneurisma foi tratado através de embolização com molas e não apresentou complicações.
