Abstract

PURPOSE OF THE STUDY

To determine the contribution of magnetic resonance (MR) imaging in the diagnosis of meniscal ossicle.

MATERIALS AND METHODS

Two cases of meniscal ossicle were evaluated by plain radiography and MR imaging. Sagittal and coronal T1-weighted (400/15), proton density and T2-weighted (2,000/20,80) sequences were performed with 0.5 T magnet.

RESULTS

Plain radiography revealed a triangular ossified body in the postero-medial aspect of the knee joint. MR images demonstrated that these ossicles were located within the posterior horn of the medial meniscus. The signal of these ossicles was isointense with that of bone marrow in all sequences.

CONCLUSION

MR findings allow the diagnosis of meniscal ossicle and help to differentiate it from osteochondral loose body.
