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.

The use of magnetic resonance imaging (MRI) in pigmented villonodular synovitis (PVS) has been well described in the literature. MRI has been used predominantly with diffuse PVS lesions. We recently had a patient with an unusual case of localized PVS of the ankle with bone and cartilage destruction. Preoperative MRI was useful in the diagnosis of localized PVS and in the planning for surgery. MRI in a patient with this lesion had not been documented previously, but should be considered whenever PVS, either diffuse or localized PVS, is suspected.

AbstractWe present the case of a 36-year-old woman with pigmented villonodular synovitis (PVNS) of the right hand. The magnetic resonance imaging (MRI) showed that the lesion had spread over an unusually wide area. Despite this, after one single operation, there has been no relapse after 5 years, with both the functional and cosmetic results remaining satisfactory.

AbstractIntra-articular (IA) and peri-articular (PA) tumors of the knee are frequently encountered by orthopaedic surgeons. Nonetheless, due to the possibility of great morbidity and potential mortality, it is important to recognize and differentiate between benign and malignant lesions in a timely manner. Therefore, the purpose of this article is to provide a concise, practical, and updated review of commonly encountered IA and PA tumors including intratendinous gout, synovial chondromatosis, schwannoma, pigmented villonodular synovitis, and synovial sarcoma, and a detailed description of differentiating features to include various imaging modalities.
