Presentation
Knee pain
Patient Data
There is a mild reduction of the medial femorotibial compartment. The patella shows tiny osteophytes. There are two ossified bodies posterior to the knee joint in the lateral view; which overlie the medial femoral condyle. There is another smaller ossified body in the lateral view which is probably in the joint cavity. There is no fracture, dislocation or bone lesion.
There is a cyst on the posteromedial side of the knee with echogenic ossified bodies in it. The cyst showed a communicating neck between the medial head of the gastrocnemius muscle and the semimembranosus tendon (image not uploaded).
Case Discussion
The case shows ossified bodies on the posteromedial side of the knee in the radiographs. The ultrasound confirms their location in a Baker cyst.
