Fig. 1From: Fibro-adipose vascular anomaly (FAVA) - diagnosis, staging and managementSurgical resection of a FAVA in calf. a-c, A girl was presented with Achilles contracture and a local mass in calf. Venography demonstrated anomalous-dilated veins, and normal orthotopic veins in the affected area. d and e, The soleus was infiltrated by diffuse heterogeneous high signal on MRI. The gastrocnemius atrophy was noted. f, The deep fascia over gastrocnemius was not obviously involved. g. The soleus underlying gastrocnemius was infiltrated by dense fibroadipose tissue and tufted venous component. h. Achilles lengthening was performed following radical resection of lesion because of significant contracture. i. Surgical specimen showed an intramuscular mass with unusually rounded venous nodules intermingled with dense fibrotic tissue and yellow fatBack to article page
