Comprehensive review of fibroadipose vascular anomaly cases at a multidisciplinary vascular anomalies center

Year: 2025

Type: article

Abstract: Background: Fibroadipose vascular anomaly (FAVA), was first described in 2014 by Alomari.This is an intramuscular lesion predominantly affecting the lower extremities; and histologically, this is characterized by dense fibrous tissue, abundant adipose content, and dilated venous channels within muscle.We described our experience with these rare anomalies.Methods: This retrospective study reviewed 29 patients diagnosed between 2013 and 2023, including clinical, imaging, histopathological, and genetic assessments.results: The cohort comprised 10 males and 19 females aged 6-45 years.Lower limb involvement occurred in 20 cases (13 gastrocnemius, seven thigh), upper limb in six, and trunk in three.No cutaneous involvement was observed, though all cases presented with limb or segmental enlargement; two showed phleboliths on MRI.Histopathology demonstrated fibroadipose tissue with dilated venous vessels.Conclusions: FAVA diagnosis is straightforward when clinical, radiologic, and histopathologic findings are integrated.Increased awareness may reduce misdiagnosis.Surgical resection remains an effective therapeutic option, providing pain relief and potential cure in selected cases.
