Sagittal T1
2 cm cyst in the posterior intercondylar notch, mainly surrounding the PCL and Humphrey's ligament.
Case Discussion
Ganglion cysts of the knee are rarely found in an exclusively intraarticular location. Cysts in the intercondylar notch are thought to arise from the synovial lining of Hoffa's fat pad or the cruciate ligaments. In this case, there seems to be no association with mucoid degeneration of the cruciate ligaments.
