Resumo
Background: Intestinal diverticulum is an abnormality resulting in the formation of a blind-ended saccular pouch that canbe acquired either congenital, true (involving all intestinal layers) or false (involving the mucosa and submucosa), withextraluminal and intraluminal type. In humans, the acquired is more frequent, the colon is the most affected segment followed by duodenum; and majority cases of duodenal diverticula remains asymptomatic, but biliary obstruction, recurrentacute pancreatitis, hemorrhagic ulcer, proximal intestinal obstruction and perforation may occur. The aim of this report isto present a case of a congenital disease in dogs, prone to misdiagnosis due to non-specific clinical signs.Case: An 8-month-old male Boxer was evaluated due to recurrent hyporexia, vomiting, melena and syncope over threemonths with signs of a possible intestinal obstruction. Physical examination showed no abnormalities except for palemucous membranes. Complete blood count revealed anemia and leukocytosis. Platelets and biochemical profiles werenormal. Abdominal ultrasound examination indicated a dilated duodenum, measuring approximately 3.36 cm in diameter,with heterogeneous fluid content and hyperechoic structures with acoustic shadow, peristalsis appeared decreased andnon-progressive. The gastrointestinal positive contrast study was performed to better evaluate abnormalities detected atultrasonography. Images after 30 min of contrast administration demonstrated a marked distension of the duodenum, filledwith contrast and a mildly filled stomach displaced to the left. Sixty min after contrast administration a marked distensionof the entire duodenum, with tortuous aspect and filled with contrast was seen. The caudal duodenal flexure was connectedto a large barium filled saccular structure that measured approximately 7 cm in diameter...(AU)
