Abstract

Fibro-adipose vascular anomaly (FAVA) is characterized by intramuscular vascular malformation with secondary overgrowth of further mesenchymal elements, particularly fibro-adipose tissue. A rare disease complicated by nonspecific, overlapping clinical and imaging features, FAVA is often misdiagnosed, causing a dilemma in its diagnostic and therapeutical management. We present a case of FAVA of the lower extremity.
