Epidemiological features of popliteal cyst in adults and frequency of associated intra-articular disorders of the knee joint were evaluated in a series of 1001 patients, randomly referring to our Institution, to undergo to magnetic resonance imaging (MRI) of the knee. Images positive for the presence of a popliteal cyst were reviewed by two of us in order to determine the presence of other associated intra-articular disorders. The incidence of popliteal cyst in the study population (4.7%) is lower than reported in previous studies performed with different imaging techniques. A communication with the joint space was almost invariably observed. We found that popliteal cyst was associated with one or more intra-articular MRI detectable disorders in 94% of the cases. The most common pathologies observed were: meniscal lesions (83%) - frequently involving the posterior horn of the medial meniscus -, chondral lesions (43%) and anterior cruciate ligament tears (32%). Although the relation between cystic and intra-articular disease of the knee warrants further investigations, our data suggest that intra-articular disorders may play a fundamental role in the pathogenesis of popliteal cyst in adults.
