Abstract
Intussusception is a common surgical disorder in puppies. Double intussusception
(DI) however, is an extremely rare form of this pathology. The authors report a
case of a 3-month-old, Shih-tzu puppy referred to Veterinary Medical Center of
Chungbuk National University, Korea with symptoms of abdominal discomfort,
intermittent vomiting and bloody diarrhea for 5 days. Ultrasonographic
examination of the
left mid-abdominal region
revealed a mass with a ‘triple case’ sign completely different from the classic
‘target sign’. The surgical intervention confirmed it to be an ileocecal DI in
ascending colon. The case emphasizes the rare ‘triple case’ sign as a
descriptive finding on ultrasonography in DI presentations.
