ABSTRACT

Diagnosis: Osteochondritis Dissecans, juvenile-type

History: 12y/o female complaining of right medial knee pain for 3 years without a history of trauma

Findings: A/P Radiograph: Area of varied lucency on the lateral aspect of the medial femoral condyle of the right knee; just inferior to this lesion, there is an area of opacity into the knee joint, suggesting chondral or osseous tissue. Both lesions c/w OCD. O/w there is normal mineralization/alignment.MRI (T1W): Area of low signal intensity on the lateral aspect of the medial femoral condyle; surrounding this area within the femur is an area of very low signal intensity c/w fluid; there is also evidence of edema within the lesion, which may suggest an unstable fragment. There is evidence of mild cartilage thinning over the fragment but no tearing. The OCD is therefore nondisplaced.

Ddx: Findings diagnostic of Osteochondritis Dissecans, likely juvenile-type.

Exam: Not Available

No MeSH data available.
