What's Your Radiographic Diagnosis?
A four-year-old intact female Schnauzer was referred to the Iowa State Veterinary Teaching Hospital for cardiac work-up after radiography of the spine indicated an enlarged cardiac shadow. The patient's clinical signs included hind limb weakness and some pain on palpation of the lumbar area. No murmurs were present; heart sounds were faint on auscultation. Thoracic radiographs and a barium shadow were made.
