This report describes the diagnostic radiographic and CT features of pleuropneumonia in a cat with wet type of feline infectious peritonitis (FIP). In a 1 year-old cat presented with respiratory distress, pulmonary mass, thickened pleural wall with mass-like structures, and a large amount of pleural effusion were identified on radiography, ultrasonography, and CT. About two months later, in addition to the pre-existing lesions, multiple nodules had developed on the intestine and left kidney. The cat was diagnosed with pleuropneumonia caused by FIP through histologic examination and immunohistochemistry. Pleuropneumonia is rarely reported in cats with FIP, and only one cat with non-effusive FIP had pyogranulomatous pneumonia as consolidated lung lobe. In the present case, pleuropneumonia was detected as multiple mass-like lesions on diagnostic imaging.

A 2-year-old, intact male, Persian exotic cat, weighing 2 kg with a history of a palpated abdominal mass was admitted to Veterinary Medical Teaching Hospital, Seoul National University. On routine complete blood count (CBC) and serum biochemical analyses, there were anemia and 0.45 of albumin to globulin ratio. A feline infectious peritonitis (FIP) virus antibody test kit was negative. Radiography, ultrasonography and computed tomography (CT) were performed. A markedly enlarged abdominal mass was found. On cytologic examination of this mass, it was diagnosed as alimentary lymphoma or pyogranulomatous inflammation. Chemotherapeutic treatment for intestinal lymphoma was provided for several weeks, but the mass size was increased and clinical signs were not improved. The cat died six days after discontinuing chemotherapy. On postmortem examination, the definitive diagnosis was FIP. This case describes a cat with FIP in which an abdominal tumor had been suspected clinically.
