[Bacterial cholecystitis with concurrent hypothyroidism in a mixed-breed dog].

A six-year-old, neutered male mixed-breed dog was presented with jaundice, fever, and abdominal pain. A bacterial cholecystitis was diagnosed and subsequently treated with antimicrobials. However, follow-up evaluation showed inadequate disease control. Over time, the dog gained weight and developed dermatological changes indicative of an underlying endocrinopathy. Subsequent diagnostics confirmed hypothyroidism, necessitating levothyroxine supplementation. In the course of the treatment of hypothyroidism the dog developed complete resolution of the bacterial cholecystitis.This case report describes the successful treatment of bacterial cholecystitis in a dog with concurrent hypothyroidism. It aims to demonstrate that the management of associated diseases may contribute to the adequate resolution of bacterial cholecystitis.
