Ultrasonographic and computed tomographic features of a true gastro-gastric intussusception with concurrent foreign bodies in a dog.

A 2-year-old intact male Cane Corso dog was presented for acute weakness, vomiting, and diarrhea. Abdominal ultrasound revealed the stomach had severe wall edema and a target appearance. Computed tomography was consistent with a gastro-gastric intussusception and concurrent mineral-like gastric foreign bodies. After reduction of the intussusception, bilateral incisional gastropexy was performed to prevent recurrence. True gastrogastric intussusception is a rare condition and should be considered if the stomach has severe wall edema with a target sign on abdominal ultrasound. Computed tomography was useful to confirm this rare diagnosis and screen the entire abdomen for concurrent lesions. Key clinical message: This case highlights the usefulness of a CT examination to confirm this rare diagnosis, to determine the position of gastric compartments, and to detect potential concurrent lesions prior to surgery.
