A 12-year-old, castrated male, mixed dog presented with a history of gradual abdominal distention for a year and anorexia recently, with abdominal radiographs showing a gastric pylorus distention. A solitary, pedunculated, heterogeneous mass arising from the mucosal layer in the pylorus with intact wall layers was identified during ultrasound and computed tomography. The gastric muscular layer was evenly thick. After surgical excision of the mass, histological examination confirmed hypertrophic pyloric gastropathy with polypoid growth and Helicobacter spp. infiltrating the gastric mucosal epithelium. This is the first reported diagnostic imaging case of hypertrophic pyloric gastropathy with Helicobacter spp. in a dog.

GE Healthcare, United Kingdom). The patient was positioned in ventral recumbency on the CT table under general anesthesia, having scanning parameters of 120 kV, 85 mA, and 0.6 mm slice thickness. Contrast study was performed after intravenous administration of 600 mgI/kg iohexol (Bon- orex 300 Inj.
6 mm slice thickness. Contrast study was performed after intravenous administration of 600 mgI/kg iohexol (Bon- orex 300 Inj.; Daehan Pharm, Korea) injected for 20 seconds using autoinjector (A–60; Nemoto Kyorindo Co., Japan), obtaining delayed phase postcontrast CT images 90 seconds after injection. A narrow-based, polypoid mass (13.
In the same study, dogs with grades 1 or 2 show at least a 4-mm-thick muscular layer in the pyloric area on ultrasonography [1]. This study shows hypoechoic pyloric muscular layer thickness of 4 mm and confirms cystic hyperplasia of the gastric mucosal epithelium and chronic inflammatory cells through ultrasound and histopathology, respectively. The results show that the present case is a grade 3 hyperplastic pyloric gastropathy.
대상 데이터
Hypertrophic gastropathy is described as a condition of unknown origin but associated with Helicobacter pylori in 90% of patients in human medicine [3]. The breeds included Maltese, Shih-Tzu, Yorkshire Terrier, and Chihuahua with mean age at presentation of 8.8 years, ranging from 3 to 15 years [1, 2]. Approximately twice as many male as female dogs are affected [1], presenting with clinical signs such as chronic vomiting, weight loss, polydipsia, depression, lethargy, anorexia, and abdominal pain [2].
이론/모형
CT examination was performed using 32-multislice CT (Revolution; GE Healthcare, United Kingdom). The patient was positioned in ventral recumbency on the CT table under general anesthesia, having scanning parameters of 120 kV, 85 mA, and 0.
성능/효과
In conclusion, an ultrasound of the gastric wall is useful for differentiating hypertrophic pyloric gastropathy from the other pyloric disease. The sonographic and CT features of hypertrophic pyloric gastropathy are intact wall layer and focal wall thickening.
