Dual-energy computed tomography molecular imaging of pigmented villonodular synovitis

Pigmented villonodular synovitis.

Pigmented villonodular synovitis.

Pigmented villonodular synovitis (PVS) is an uncommon, usually monoarticular disorder encountered mainly in adults. A boy and a girl, both 7 years old, were referred because of recurrent knee effusions. Both were medically treated for other rheumatic disorders for five years. PVS was diagnosed by arthroscopy and synovectomy was curative in both cases.

Pigmented villonodular synovitis of the temporomandibular joint - computed tomography and magnetic resonance findings: a case report

Pigmented villonodular synovitis (PVNS) is a benign but locally aggressive and destructive disease originating in the synovial membranes. It is a proliferative disorder of unknown etiology. Involvement of the temporomandibular joint (TMJ) is very rare. Computed tomography clearly reveals areas of lytic bone erosion and sclerosis, and also clearly defines the extent of the tumor which is the foc...

Bilateral pigmented villonodular synovitis of the knee

Pigmented villonodular synovitis is a disorder resulting in a villous, nodular, or villonodular proliferation of the synovium, with pigmentation related to the presence of hemosiderin. These lesions are almost exclusively benign with rare reports of malignancy. Pigmented villonodular synovitis can occur in a variety of joints and at any age but most often occurs within the knee in the young adu...

Localized pigmented villonodular synovitis of the knee.

Pigmented villonodular synovitis (PVNS) is a well-recognized lesion that may affect any joint but is frequently found in the knee. It is a rare condition, especially in the localized form, and is still cause for discussion regarding to its pathogenesis and treatment. We report four cases of localized PVNS each one presenting with different clinical signs and symptoms. In one of our cases, a ped...
