Villonodular Synovitis of the Ankle and MRI : A Case Report
نویسندگان
چکیده
Abtract: Although most common in the hip and knee joints, pigmented villonodular synovitis (PVNS) has also been reported to occur in the ankle. The distinctive appearance of PVNS on magnetic resonance imaging (MRI) has proven to be useful in both the diagnosis and treatment of this pathologic process. The following is the report of a case that illustrates the utility of MRI in determining the extent of soft tissue and osseous involvement of PVNS about the ankle. This information is especially helpful in planning subsequent surgical intervention.

Two main forms include a diffuse form that involves the whole synovial lining of a joint, bursa, or tendon sheath, and a less common localized form. The diffuse form typically involves the large joints, while the localized one typically occurs around the small joints of...
متن کاملPigmented villonodular synovitis (PVS) A case report.
Pigmented villonodular synovitis (PVNS) is benign proliferative disorder of the synovium of unknown origin. PVNS is divided into intra-articular and extra-articular form which may present as i) diffuse or ii) localised/nodular form. It is commonly seen in knee joint but hip, ankle, shoulder, wrist & other joints can be involved. It is usually seen in young adults from 20-50 years of age. It is ...

Pseudoaneurysm of the dorsalis pedis artery is uncommon and is usually associated with a history of trauma to the vessel. Without such a history, the diagnosis may be challenging, because the mass may be confused with other common soft tissue masses in the foot. This case report describes a 67-year-old man with an idiopathic pseudoaneurysm of the dorsalis pedis artery that mimicked pigmented vi...
