IMAGING DIAGNOSIS: THE COMPUTED TOMOGRAPHY FEATURES OF A PLEUROPERITONEAL HERNIA IN A CAT

An 8-year-old female neutered domestic short hair cat presented for investigation of poorly controlled diabetes mellitus. Thoracic radiographs identified a soft tissue opacity in the caudoventral thorax adjacent to the diaphragm. Computed tomography (CT) then characterized a pleuroperitoneal hernia with cranial displacement of a portion of the liver within the hernia. A pleuroperitoneal hernia was confirmed and repaired via exploratory laparotomy. This is the first description of the CT features of a pleuroperitoneal hernia in a cat.
