Acute appendicitis with associated trichobezoar of feline hair

A trichobezoar is an accumulation of ingested hair that forms a mass within the gastro-intestinal tract. Thrichobezoars usually consist of human hair and are known to cause obstruction and even perforation of gastrointestinal organs. There have been approximately seven reported cases of acute appendicitis with association trichobezoars found at the time of appendicectomy. We report a unique case of acute appendicitis with an associated trichobezoar of feline hair. A 15-year-old male presented with a 24-hour history of abdominal pain. A computed tomography scan demonstrated features of appendicitis with several hyperdensities within the base of the appendix. At the time of appendicectomy, the appendix was found to be perforated at the base. Faecoliths were identified containing numerous short, light-coloured hairs. Following the procedure, the family confirmed that they have a pet cat with short, light-coloured hair. The patient had an uneventful recovery.
