Lower Extremity Fibro-Adipose Vascular Anomaly-Case Report

Area of Science:

• Vascular Surgery
• Pediatric Orthopedics
• Medical Imaging

Background:

• Fibro-adipose vascular anomaly (FAVA) is a rare, painful vascular malformation.
• It typically presents with muscle fibrofatty infiltration, often in the lower limb.
• FAVA can lead to extremity contracture and limited mobility.

Observation:

• A case report from Portugal details a 9-year-old female with a painful right leg mass.
• MRI confirmed a 5x4x4 cm mass consistent with FAVA in the peroneus longus muscle.
• The patient presented with symptoms indicative of FAVA.

Findings:

• Surgical resection of the involved peroneus longus muscle was performed.
• The patient experienced a 6-month follow-up with no adverse clinical events.
• This case represents the first successful surgical treatment of FAVA reported in Portugal.

Implications:

• Early surgical intervention for FAVA can prevent debilitating long-term consequences.
• Distinguishing FAVA from venous malformations is crucial for appropriate management.
• Surgical treatment is a viable option for FAVA, improving patient outcomes and function.
