Intramuscular Venous Malformation in an Infant Masquerading as Recurrent Gonarthritis

Vascular malformations, commonly misdiagnosed and mistreated as hemangiomas, are rare congenital abnormalities in the vasculature. Venous malformation (VM) is one of the most common vascular malformations and is easily diagnosed by skin discoloration when it involves the skin or superficial tissue. However, deep-sited VM may only manifest as a subcutaneous mass or can even be asymptomatic.1,2 Particularly in patients with predominantly intramuscular VM, symptoms often develop later in life as physical activity induced pain with no fever or inflammatory responses emerging except in the case of infectious complications.
