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%).
对14只猫肠道肥大细胞瘤（MCT）的超声特征进行了回顾性研究。平均年龄为13.4±2.5岁。有16个局灶性肠道肿瘤和1例弥漫性黏膜下浸润。最常见的表现是局灶性、低回声壁增厚，呈非圆周性和偏心性（9/16个肿瘤）或圆周性、不对称性和偏心性（5/16个肿瘤）。9只猫的病变位于空肠或十二指肠，4只位于回盲结肠交界处，1只猫有结肠肿块。6个MCT的肠壁分层改变但未消失，超声检查最常受累的层次是固有肌层。9只猫有腹部淋巴结肿大，7只与转移性疾病有关。超声检查在肝脏（1/4只猫）或脾脏（0/3只猫）中未常规检测到转移性疾病。14只猫中有4只（29%）同时存在小细胞（T细胞）淋巴瘤。
