Lower Extremity Fibro-Adipose Vascular Anomaly-Case Report

Joana Ferreira et al. Ann Vasc Surg. 2020 Jul.

Abstract

Fibro-adipose vascular anomaly (FAVA) is a painful complex vascular malformation, characterized by muscle fibrofatty infiltration, usually in lower limb, associated with contracture of the ipsilateral extremity. This article describes the first case of FAVA reported in Portugal successfully treated with surgery. A 9-year-old female was admitted complaining of a painful mass in the right leg. The MRI scan showed the presence of a 5 × 4 × 4 cm mass in the right leg consistent with FAVA located in the peroneus longus muscle. The patient underwent resection of the involved muscle. She had 6 months of follow-up without any relevant clinical event. The authors also highlight the difference between FAVA and venous malformation. Early surgery is a treatment option that can prevent long-term consequences, as contracture and movement limitation.
