There were some really challenging cases at KCC this week. Here are a few summaries;
Case 1
11 year old Golden Retriever, lame on the right hind limb. Here’s a link to the case; imagine you are in the hot seat and give an oral description, list of differentials, and next steps.
Case 2
8 year old Boxer with mass on the right thorax. On thoracic raidographs, there was increased soft tissue opacity in the cranial mediastinum causing the cardiac silhouette to be displaced caudally. The carina was between the 7th and 8th ribs. There was also pleural effusion in the right hemithorax, and a lytic rib with associated body wall and pleural mass. Several sternebrae were lytic and collapsed. Differential diagnoses for mediastinal mass and multiple aggressive bone lesions included primary bone neoplasia with metastasis, hemangiosarcoma, round cell tumor and chemodectoma. Diagnosis: Lymphoma.
Case 3
3 year old female neutered cat with tachypnea. There was pleural effusion in the left hemithorax with retraction of the lung lobes and pleural thickening. The left caudal lung lobe had increased opacity and an irregular gas opacity visible on both projections. Differentials were pyothorax and lung abscess with secondary pyothorax. Further diagnostics could have included ultrasound or a horizontal beam radiograph to look for a fluid-gas interface. Diagnosis: pulmonary abscess with secondary pyothorax.
