title: Intra-articular hemangioma of the knee as a cause of knee pain.
abstract: We report the case of a young patient with knee pain, limited range of motion, and swelling due to an intra-articular hemangioma. Clinically, the symptoms and findings were similar to those of a meniscal lesion. The diagnosis of an intra-articular tumor was made using magnetic resonance imaging. The tumor was excised, and the definitive diagnosis was made histologically. After tumor excision, the patient was pain free.
