Scrotal hernia with irreducible small intestine in an intact ferret (Mustela putorius furo)

Background: Scrotal hernia is an inguinal hernia, in which the visceral organs protrude through the inguinal ring into the scrotum. No clinical report of a scrotal hernia in a ferret has been documented based on the literature search. Case Description: A one-year-old intact male ferret was presented with a history of several months of slowly progressive, right, cord-like scrotal swelling. On physical examination, a scrotal hernia was suspected and the protruding contents were unable to be reduced. Radiography and ultrasonography revealed a herniated small intestinal loop inside the swollen scrotum which confirmed the diagnosis of irreducible scrotal hernia. Following reduction of the small intestine into the abdomen, inguinal herniorrhaphy and castration were performed. Recurrence and other clinical abnormalities were not identified during post-operative follow-ups at 3 months and 1 year. Conclusions and Case Relevance: This case involved a scrotal hernia in an intact male ferret with an irreducible herniated small intestine. This report describes the diagnostic findings and surgical treatment with a successful outcome. Scrotal hernia should be considered in ferrets with scrotal swelling.
