Presentation
pain in right knee joint.
Patient Data
There is increased width of body of lateral meniscus, which is seen on more than 3 contigenous saggital images, represent near complete discoid meniscus. Linear intrasubstance hyperintense signal is seen in lateral meniscus on gradient and PD fat sat images, which reaches upto its anterior margin – represents its horizontal tear.
Small fairly well defined lobulated hyperintense area is seen adjacent to the anterior horn of lateral meniscus on T2W and PD fat sat images – probably represent parameniscal cyst rather than part of joint effusion. There is minimal synovial joint effusion.
Case Discussion
These findings represent discoid meniscus with tear.
