A 12-year-old castrated male miniature pinscher dog presented with right forelimb lameness. An expansile osteolytic lesion of the right humerus was conspicuous on right forelimb radiographs. Thoracic and abdominal radiographs showed multiple lytic bone lesions on the right scapula, ribs, vertebrae, femurs and pelvis. Additionally, an expansile osteolytic lesion was observed in two thoracic vertebrae and two ribs. Many plasma cells were identified on fine-needle aspiration of the right humerus expansile osteolytic lesion, and monoclonal gammopathy consistent with multiple myeloma was confirmed on serum protein electrophoresis. The expansile osteolytic lesion, an extraordinary radiographic feature of multiple myeloma in dogs, should be considered as a possible radiographic finding of multiple myeloma.
