Patient Data

There is a triangular lesion within the posterior horn of the medial meniscus that follows marrow signal and has a low signal rim on all sequences.

The body of the lateral meniscus is mildly enlarged indicating a discoid morphology.

There is moderate delamination of the articular cartilage of the weight-bearing surface of the lateral femoral condyle. 


There is a triangular ossific density in the posterior aspect of the medial compartment of the tibiofemoral joint. 

Case Discussion

Typical example of a meniscal ossicle, which is a relatively rare ossicle that should not be confused with a fabella, which would be lateral and extraarticular.
