Magnetic resonance imaging of pigmented villonodular synovitis: a report of two cases. 1987

C E Spritzer, and M K Dalinka, and H Y Kressel

The magnetic resonance imaging characteristics of two surgically proven cases of pigmented villonodular synovitis are reported. On the short TR/TE pulse sequences, the synovium has an intermediate signal intensity. Long TR/TE pulse sequences show the synovium containing areas of increased signal interspersed with decreased signal. Hemosiderin deposition is believed to account for the areas of decreased signal; the increased signal results from fluid and inflamed synovium.

D013586	Synovitis, Pigmented Villonodular	Diffuse outgrowth arising from the SYNOVIAL MEMBRANE; SYNOVIAL BURSA; or TENDON sheath around the joint cavity, with extension to surrounding soft tissue. It is characterized by pigmented HEMOSIDERIN-containing MACROPHAGES; FOAM CELLS; and multinucleated GIANT CELLS. It usually occurs in the hands and feet, and around large joints, such as in the ankle and knee joints.
