Giant Melon seed Bodies in Painless Shoulder Swelling

Melon seed bodies are a non-specific manifestation of chronic synovial inflammation associated with various arthritides such as tubercular, rheumatoid, and seronegative arthritis. Characteristic magnetic resonance imaging (MRI) appearance of these bodies differentiates them from other differential diagnoses (such as synovial chondromatosis and pigmented villonodular synovitis). Ultrasonography and MRI, in combination with clinical and laboratory details, can suggest the possible etiology. Medical management of the underlying cause, along with arthroscopic removal of pathognomonic bodies, is the preferred treatment.
