title: Unusual knee swelling: a diagnostic dilemma.
abstract: Haemangioma is a common benign soft tissue tumour. Intramuscular haemangiomas are rare but pose quite a diagnostic challenge. An intramuscular haemangioma can be confused with other soft tissue swellings including abscess. We present a case report of swelling around the knee in an adolescent patient, which was ultimately diagnosed and treated as intramuscular haemangioma of the quadriceps muscle.
