Reason: assess for cause of L. leg tenderness, assess for soft tissue tumors History: pain in the medial L. leg, H/O Schwannoma The marrow signal intensity of the tibia and fibula is normal. The musculature appears normal and we see no soft tissue mass. Although this study was not protocoled for detailed evaluation of the knee, there appears to be mild osteoarthritis and mild synovial enhancement suggesting mild synovitis. There is a lobulated collection of fluid signal intensity with peripheral enhancement anterior to the lateral meniscus, which may represent a perimeniscal cyst or ganglion.
We see no specific findings to account for the patient's leg pain. Mild osteoarthritis of the knee and possible perimeniscal cyst are not optimally evaluated on this study. If further imaging is clinically warranted, dedicated knee MRI may be considered.
