“…The potential of identifying a gastric tumour on radiographs depends on multiple variables, including tumour size, discrete mass vs diffuse lesion, and the presence of luminal gas providing spontaneous contrast. 24 While radiography has been largely replaced by ultrasound, endoscopy and, more recently, CT in the diagnostic work-up of gastric neoplasia in veterinary patients, 25 our results support its value as a screening tool. Conventional radiography is inexpensive, widely available and should be considered a valid initial test when gastric neoplasia is clinically suspected, especially in clinical settings where US evaluation is not readily available.…”

Objectives The purpose of this study was to describe B-mode and colour Doppler ultrasound (US) features of gastric lymphoma in cats. Methods Cats with histopathological or cytological confirmation of gastric lymphoma that underwent abdominal US were included in this retrospective study. Clinical signs were recorded and radiographs reviewed when available. Gastric lesions were ultrasonographically evaluated for location, distribution, wall layering, echogenicity and thickness. Colour Doppler assessment was based on vessels, location and direction. Results Forty-five cats were included. All presented with vomiting, 7/45 (15.5%) with haematemesis. Radiographs were available in 27/45 cases, and demonstrated a gastric mass in 19/27 (70.4%) cases. The most common US appearance was transmural wall thickening with absent layering 42/45 (93.3%) and hypoechogenicity 39/45 (86.7%). Median maximum thickness was 2.1 cm. Ulceration or erosion was suspected in 23/45 (51%) cases, two of which perforated. Colour Doppler images were available in 33/45 cases. The most common Doppler finding was transmural vessels coursing perpendicularly to the lumen in 14/33 (42.4%). Abdominal effusion was uncommon (n = 11/45; 24.4%). Regional lymphadenopathy was frequent, observed in 44/54 lymph nodes reviewed on US, and US suspicion of splenic, hepatic and intestinal lymphomatous infiltration was reported in 24/45 (53.3%) cases. Conclusions and relevance The most common US appearance of gastric lymphoma was transmural hypoechoic segmental wall thickening with layering loss. Location and distribution were variable. Colour Doppler displayed increased blood supply with a predominant pattern of perpendicular vessels, possibly representing aberrant arteries originating from subserosal and submucosal plexus. Lymphomatous infiltration of lymph nodes and other abdominal organs was frequent, confirming local and distant aggressiveness of gastric lymphoma in cats. Vomiting and haematemesis were frequently associated with the suspicion of ulcer on US. Perforation was a rare occurrence.

“…[15][16][17] Pyloric adenocarcinomas are usually annular and stenosing. 14 In this study, adenocarcinomas were found to form thickening lesions that involved the outer layer. In previous report, gastric adenocarcinomas display diffuse or segmental wall thickening lesion.…”

“…Adenomas are polypoid masses composed of moderately atypical glandular epithelium surrounded by lamina propria. 14 Adenomas present features of nonneoplastic lesions that include hypertrophic gastritis and hyperplastic polyps. 14 In dogs, adenocarcinoma is malignant and epithelial in origin, infiltrates submucosal areas, and is often located in small curvatures and pylori.…”

“…In this study, GISTs were found to form a mass lesion that involved the outer layer. Canine GIST are indeed of smooth muscle origin, 14 and CT makes it possible to identify the layered structure of the gastric wall. 8 The involved area and lesion shape may help differentiate GIST.…”

Pyloric outflow obstructions can be caused by several types of lesions. When a thickened gastric wall and pyloric mass are detected, malignant neoplasia must be differentiated from chronic hypertrophic pyloric gastropathy. CT can characterize gastric tumors. However, based on the authors’ review of the literature, there is limited information about the CT findings of pyloric lesions. The purpose of this retrospective case series study was to assess the CT findings of canine pyloric lesions. The following CT parameters were recorded: anatomical area, involved area, lesion shape, growth patterns of wall thickening lesions, enhancement pattern of the lesion in the early and delayed phases, lymphomegaly, and pulmonary metastasis. Seventeen dogs were included in this study and had the following final diagnoses: hyperplasia (five dogs), adenoma (five dogs), adenocarcinoma (three dogs), gastrointestinal stromal tumor (GIST; two dogs), polyposis (one dog), and pyogenic granuloma (one dog). Hyperplasia, adenoma, and polyposis formed mass lesions that involved the mucosal layer. Lymphomegaly was detected in two Jack Russell terriers with hyperplasia; however, the causes were unknown because we did not perform biopsies. All adenocarcinomas formed wall‐thickened lesion that involved the outer layer, with lymphomegaly. All GISTs formed mass lesion that involved the outer layer. The pyogenic granulomas formed symmetric wall‐thickened lesion that involved the mucosal and outer layers. CT facilitated the characterization of canine pyloric lesions using contrast enhancement, based on the involved area and lesion shape. However, polyposis may require caution in diagnosis based on CT findings alone.
