Intramuscular Arteriovenous Hemangioma of Thigh: A Case Report and Review of Literature

INTRODUCTION: Skeletal muscle hemangiomas are uncommon soft tissue tumors; more than 90% are misdiagnosed initially. They present as chronic pain and swelling in a muscle with or without a history of trauma. Magnetic resonance imaging is the investigation of choice. Many treatment modalities for the symptomatic hemangiomas are available of which surgical excision is the most preferred. CASE REPORT: We present an unusual case of pain, swelling, and restriction of movements in the right knee following an episode of trauma in an 8-year-old boy diagnosed to have intramuscular arteriovenous hemangioma in the vastusmedialis and vastusintermedius for which he was treated by surgical excision and followed for 2 years and found to have no recurrence. CONCLUSION: Skeletal muscle hemangiomas are completely treatable; the knowledge of their natural history, clinical findings, and imaging appearances are of great importance for proper diagnosis and treatment.
