Arthrographic Findings in Meniscal Cysts

Abstract

Meniscal cysts have definite pathologic characteristics which may be visible on arthrography. Medial cysts usually present as masses. The more common lateral cysts show irregular meniscal tears and puddling in the cystic spaces. These cysts simulate popliteal cysts which require simple excision. Meniscal cysts require meniscectomy and, therefore, preoperative diagnosis by arthrography can be important.
