Synovial hemangioma, Diagnostic MRI, Arthroscopy, Chronic knee pain


Synovial hemangioma is an uncommon cause of chronic anterior knee pain. The non-specific clinical presentation leads to delay in diagnosis. MRI is diagnostic and should be considered early in evaluation to plan treatment and prevent functional disability. We present a case of unilateral synovial hemangioma of the knee in a child with pain, swelling and restricted knee mobility. Arthroscopy can be diagnostic and therapeutic in such cases.
