This report describes the unusual ultrasonography features of chronic hypertrophic pyloric gastropathy intwo dogs - a 12-year-old neutered male Pekingese (case 1) and an 11-year-old spayed female Shih Tzu (case 2) -with chronic vomiting and weight loss. Chronic hypertrophic pyloric gastropathy can be observed as the focal thickeningof the pyloric wall with normal layers on ultrasonography images. However, in case 1, gastric neoplasia could notbe ruled out because of the presence of regional lymph node enlargement; in case 2, an intussusception was tentativelydiagnosed because of a mass within the pylorus, which appeared to be connected to the descending duodenum onthe longitudinal image. In both cases, focally thickened pyloric walls were demonstrated through exploratory laparotomy,and the histopathological diagnosis of chronic hypertrophic pyloric gastropathy was made. Ultrasonography is usefulfor imaging the gastrointestinal tract, and the typical ultrasonographic features of chronic hypertrophic pyloricgastropathy have been reported. However, the possibility, that chronic hypertrophic pyloric gastropathy can presentunusual ultrasonographic findings similar to those of tumors or intussusception, should also be considered.
