Unusual presentation of bilateral stifle osteochondritis dissecans in two labrador retrievers

13 Jul 2018

There are few published reports of CT findings for the diagnosis of stifle osteochondritis dissecans (OCD) in the dog. This report describes the radiographic and multidetector CT (MDCT) findings of two cases with bilateral stifle osteochondrosis and OCD lesions. In both cases, radiographs did not provide a complete picture of the pathology and CT was needed for a definitive diagnosis. In case 1, CT showed bilateral defects on the caudomedial part of the lateral femoral condyles with joint mice within the cranial right stifle joint. In case 2, CT showed large bilateral joint mice within the intercondylar fossa originating from the medial aspect of the lateral femoral condyles as well as a defect on the right medial femoral condyle. MDCT provided an accurate diagnosis in both these cases and facilitated surgical planning.
