Suspected intrapericardial lipoma in a standard schnauzer

Abstract

A five-year-old, male, neutered standard schnauzer presented for vomiting, diarrhoea and fever. A large intrapericardial fatty mass was identified on advanced imaging. The patient underwent a median sternotomy and exploratory coeliotomy to remove the fatty mass measuring 100 mm x 76 mm x 66 mm, the histopathology of which revealed a large fatty mass with necrosis and inflammation. This is the largest reported intrapericardial fatty mass in the veterinary literature. CT at 28 weeks postoperatively revealed no evidence of recurrence.
