A liver mass was incidentally revealed in a 10-year-old male neutered Himalayan cat on radiographic examination conducted in a local animal hospital. The abdominal distention had worsened over the past five months, along with intermittent vomiting and nausea for two weeks. Serum chemistry was unremarkable, except for elevated alkaline phosphatase and gamma-glutamyl transferase levels. Radiography revealed a round-shaped soft mass in the cranial abdomen. Abdominal ultrasonography showed a well defined, massive, fluid-filled cyst with multiple lobes, and heterogeneous echogenicity in the pancreas. Computed tomography examination revealed hypoplasia of the left lobes of the liver, but the vascular changes and enhancement of the mass were not observed on contrast computed tomography images. The herniation of the abdominal fat through the diaphragm was incidentally observed on sonography and computed tomography scan. The patient was tentatively diagnosed with pancreatic cyst. The laparotomy revealed that the origin was not related to the pancreas, but was suspended from the liver. The mass was multilobular and filled with approximately 120 ml of fluid containing a few white blood cells. The patient recovered from anesthesia, but showed postoperative respiratory depression and died of cardiac arrest 15 hours later. Histopathologically, the mass was definitively diagnosed to be hepatic cellular carcinoma.

Persistent left cranial vena cava (PLCVC) is a remnant vessel connected with the coronary sinus and draining into the right atrium. A 3-month-old intact male Bichon Frise was evaluated for the presence of a mechanical murmur auscultation in the local animal hospital. No significant clinical signs were present on physical examination except mechanical murmur. Patent ductus arteriosus (PDA) was diagnosed in the imaging procedure. During the left thoracotomy, PLCVC was found. The vascular malformation made the surgical process difficult by hiding PDA from the left thoracotomy surgical view. PLCVC and the vagus nerve was carefully dissected and lifted to secure a clear surgical view of PDA. The ductus arteriosus was ligated. Computed tomography angiography (CTA) was performed postoperatively. On CTA, left brachiocephalic vein retaining connection with the coronary sinus draining into the right atrium was observed. CTA is highly recommended for dogs with PDA to provide better postoperative results.
