A 13-year-old neutered female Keeshond-cross was evaluated because of a history of melena, anemia, hematemesis, vomiting, and high serum liver enzyme activities over a 1.5-year period.
Abdominal ultrasonography revealed a hyperechoic mass in the gallbladder. In the gallbladder mass itself, a distinct linear blood flow pattern was detected by use of color flow Doppler ultrasonography.
A cholecystectomy was performed, and clinical signs resolved. Samples of the mass were examined histologically and immunohistochemically, and findings supported a diagnosis of neuroendocrine tumor of the gallbladder.
Tumors of the biliary tree are a potential source of blood loss into the gastrointestinal tract. Color flow Doppler ultrasonography in conjunction with conventional grayscale ultrasonography may be useful in evaluation of the gallbladder in dogs. When echogenic material is detected in the gallbladder, it is important to evaluate the region for blood flow.
一只13岁已绝育的雌性荷兰毛狮犬杂交犬，因在1.5年期间出现黑便、贫血、呕血、呕吐及血清肝酶活性升高的病史而接受评估。
腹部超声检查发现胆囊内有一个高回声肿块。在胆囊肿块本身，通过彩色多普勒超声检测到明显的线性血流模式。
实施了胆囊切除术，临床症状消失。对肿块样本进行了组织学和免疫组织化学检查，结果支持胆囊神经内分泌肿瘤的诊断。
胆管肿瘤是胃肠道失血的潜在来源。彩色多普勒超声结合传统灰阶超声可能有助于评估犬的胆囊。当在胆囊中检测到回声物质时，评估该区域的血流情况很重要。
