Ultrasonographic features of canine abdominal malignant histiocytosis (MH) of 16 dogs are reported. The most common finding was the presence of hypoechoic nodules in the spleen, some of which caused distortion of the splenic margin. The liver was the second-most commonly affected organ. Hepatic ultrasonographic features were highly variable, including hypoechoic, hyperechoic, or mixed echogenic lesions. Other common ultrasonographic abnormalities included hypoechoic nodules in the kidneys and mesenteric and medial iliac lymphadenopathy. The results of this study suggest that the ultrasonographic appearance of canine abdominal MH is nonspecific, and definitive diagnosis requires cytologic or histologic examination.
报告了16只犬腹部恶性组织细胞增多症（MH）的超声特征。最常见的发现是脾脏出现低回声结节，其中一些导致脾脏边缘变形。肝脏是第二常见的受累器官。肝脏超声特征高度可变，包括低回声、高回声或混合回声病变。其他常见的超声异常包括肾脏低回声结节以及肠系膜和髂内侧淋巴结病。本研究结果表明，犬腹部MH的超声表现不具有特异性，明确诊断需要进行细胞学或组织学检查。
