title: Space-occupying leiomyoma in the pelvic canal of a dog.
abstract: A large space-occupying mass was found in the pelvic canal of an 11-year-old, entire female shih tzu with rectal tenesmus and dyschezia. Computed tomography revealed an extraluminal mass located on the dorsal aspect of the rectum, causing complete rectal obstruction. Histopathological examination of biopsy tissue identified it as a leiomyoma. The tumour was successfully removed by blunt dissection, via a dorsal approach to the rectum, and there were no complications after surgery.
