Fibro-adipose vascular anomaly, also known as FAVA, is a type of vascular anomaly that is both rare and painful. FAVA is characterized by tough fibrofatty tissue taking over portions of muscle, most often contained within a single limb. FAVA also causes venous and/or lymphatic abnormalities.[1]
Though FAVA has only been recognized as a distinct vascular anomaly, separate from common venous malformations, within the past ten years, FAVA a distinct congenital disorder.[2]
