TLDR
The sonographic features of intestinal mast cell tumors (MCT) were reviewed in 14 cats and the most commonly affected layer on ultrasound examination was the muscularis propria.Abstract:
The sonographic features of intestinal mast cell tumors (MCT) were reviewed in 14 cats. The mean age was 13.4 ± 2.5 years. There were 16 focal intestinal tumors and one diffuse submucosal infiltrate. The most common pattern was focal, hypoechoic wall thickening that was noncircumferential and eccentric (9/16 tumors) or circumferential, asymmetric, and eccentric (5/16 tumors). Nine of the cats had lesions in the jejunum or duodenum, four were at the ileocecocolic junction, and one cat had a colonic mass. Six MCTs had altered but not loss of wall layering, and the most commonly affected layer on ultrasound examination was the muscularis propria. Nine cats had enlarged abdominal lymph nodes, and seven were due to metastatic disease. Metastatic disease was not routinely detected by ultrasound in the liver (1/4 cats) or the spleen (0/3 cats). Concurrent small cell (T cell) lymphoma was present in four of 14 cats (29%).read more

TL;DR: The evidence supporting this review is grade II, III and IV, derived from prospective studies, retrospective case series, reviews, extrapolation from other species, pathophysiological justification and the combined clinical experience of those working in the field.

Clinicopathological and ultrasonographic features of cats with eosinophilic enteritis.
TL;DR: In this paper, the authors evaluate the clinical and ultrasonographic findings in cats with histologic evidence of eosinophilic inflammation on gastrointestinal biopsy and conclude that the presence of a prominent intestinal muscularis layer and palpably thickened intestines can serve as biomarkers for the presence in cats of chronic intestinal signs.

Ultrasonographic measurement of the relative thickness of intestinal wall layers in clinically healthy cats.
TL;DR: The normal sonographic thickness of the individual layers (ie, mucosa, submucosa, muscularis and subserosa-serosa) of the intestinal wall was evaluated in 20 clinically healthy cats to provide baseline information that might be useful in evaluating intestinal disorders affecting preferentially some of theestinal layers.

TL;DR: Four cats with feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) are described and FGESF should be considered as a differential for intestinal masses in cats.

Ultrasonographic evaluation of gastrointestinal diseases in small animals
TL;DR: Sonographic findings of 18 dogs and four cats with gastrointestinal (GI) diseases were reviewed and Ultrasonographic appearance of gastrointestinal neoplasms, gastrointestinal obstruction, ileus, intussusception, inflammatory GI diseases, and congenital disorders are discussed.

Diagnostic value of ultrasonography in differentiating enteritis from intestinal neoplasia in dogs.
TL;DR: A multivariate analysis showed that loss of wallLayering alone was an excellent predictive factor in differentiating intestinal tumor from NSE and dogs with loss of intestinal wall layering were 50.9 times more likely to have a tumor than enteritis.

Ultrasonographic evaluation of the muscularis propria in cats with diffuse small intestinal lymphoma or inflammatory bowel disease.
TL;DR: The ultrasonographic pattern is associated with histologic infiltrates in the mucosal and submucosal layers of small intestine and older cats with muscularis layer thickening are more likely to have T-cell lymphoma than IBD.

TL;DR: The results of this study indicate that ultrasonography is a valuable tool for the diagnosis of feline alimentary lymphosarcoma and that biopsies can be obtained under ultrasonographic guidance.

Ultrasonographic diagnosis of gastrointestinal smooth muscle tumors in the dog
TL;DR: It is concluded that ultrasonography is more sensitive than survey radiography in the detection of GI smooth muscle tumors, and may present specific features to distinguish smoother muscle tumors from other types of GI tumors.
