In T2-weighted, fat-suppressed coronal MRI, fibro-adipose vascular anomaly (FAVA) is visible as a hyperintense lesion in the left gastrocnemic muscle.
Fibro-adipose vascular anomaly (FAVA) is a variant of a venous malformation located intramuscularly, often progressively associated with connective tissue proliferation. The entire FAVA could be surgically removed in this case. As a result of the substantial manipulation of a nerve that was encased by the malformation, there was postoperative impairment of the nerve. However, it recovered in this patient without further surgical intervention.
In the meantime, the girl has undergone rehabilitation for more than two years, which is not yet completely finished. This shows that a painful and progressive pre-existing condition that has lasted for years cannot easily be fully cured by surgical intervention. Among other things, a long period of pain therapy and intensive physiotherapeutic treatment is necessary.
