Abdominal computed tomographic examination of a 10-year-old sexually intact female Vietnamese potbellied pig was performed because of ongoing abdominal distention of six months duration. The study revealed a severely expansive well-defined heterogeneously contrast-enhancing mass with a soft tissue to fluid dense parenchyma occupying the majority of the caudal abdomen. The dimensions of the mass were 30 cm craniocaudal × 35 cm lateromedial × 17.8 cm ventrodorsal, and it caused severe dorsal displacement of the colon and small intestines, lateral compression of the spleen, and cranial displacement of the stomach and liver. The left ureter appeared to course through the parenchyma of the mass. While the origin of the mass was not definitely identified in the CT study, the left ovary and uterine horn were the primary considerations. A ventral abdominal laparotomy under general anesthesia was planned for surgical removal of the mass. Upon exploration it was confirmed that the left ureter coursed through the mass. Dissection of the left ureter was not possible so a left nephrectomy was performed after isolating the ureter and associated vessels. The mass had soft tissue attachments to the wall of the caudal vena cava, needing repair after dissecting it free from the mass. The uterine body was transected after stapling with TA 55 3.5 mm staples and oversewn. Histopathology of the mass was consistent with leiomyoma. The patient recovered well from the procedure and was discharged after six days of hospitalization. At one month follow-up, the patient was back to her regular routine.
