title: Colic and dyspnea in a dog.
abstract: Volvulus and incarceration of bowel by a hernia may cause a closed-loop obstruction, possibly with associated intramural accumulation of gas and/or blood. Standing lateral projections optimize diagnosis of strangulating obstructions. Accumulation of only fluid in the obstructed loop may resemble a tumor. Radiographic signs of exudation and peritoneal fluid accumulation may develop with closed-loop obstructions.
