Abstract
For the first time in veterinary literature, magnetic resonance and arthros copic features of a discoid lateral meniscus in a dog are described. A 15-m onth-old Labrador Retriever with a history of mild intermittent left hindli mb lameness was referred to our clinic. Physical examination revealed mild joint effusion of the left stifle and absence of a cranial drawer motion an d tibial compression test. Survey radiographs demonstrated mild joint effus ion and peri-articular new bone formation. Low-field magnetic resonance tom ography of the left stifle joint demonstrated injury of the cranial cruciat e ligament and a discoid lateral meniscus. Two weeks later, arthroscopy rev ealed a partial tear of the cranial cruciate ligament with mild synovitis. Furthermore. some fibres inserted abnormally cranial to the inter-meniscal and cranial tibial ligament of the medial meniscus. The lateral meniscus wa s discoid in shape. Subsequent arthrotomy confirmed the diagnoses. Discoid meniscus is a rare finding in the dog with unknown clinical relevance where as it is well known in humans.
