Computed tomography (CT) and ultrasonography (US) may be used to assist staging in dogs with lymphoma. The imaging features of splenic and hepatic infiltration have never been directly compared in the same population of dogs.
The aim of this retrospective study was to describe and compare the CT and US findings of the liver and spleen in dogs with confirmed hepatic and/or splenic lymphoma and compare imaging and cytological diagnoses.
CT and US studies of 18 dogs with multicentric lymphoma involving the liver and/or the spleen were retrospectively evaluated. US detected abnormalities more frequently than CT in the spleen with lymphoma, whereas CT detected abnormalities more frequently in the liver with lymphoma. The two diagnostic imaging modalities often disagreed in the findings, including the imaging classification of the organ as normal or abnormal.
US and CT often disagree in the imaging findings present in hepatic and splenic lymphoma. The results of this study suggest that cytologic evaluation of both the liver and spleen is advisable regardless of their US or CT appearance for detection of lymphoma.
计算机断层扫描（CT）和超声（US）可用于辅助犬淋巴瘤的分期。在同一批犬中，从未直接比较过脾脏和肝脏浸润的影像学特征。
本回顾性研究的目的是描述和比较经证实患有肝和/或脾淋巴瘤的犬的肝脏和脾脏的 CT 和 US 表现，并比较影像学和细胞学诊断。
对 18 例涉及肝脏和/或脾脏的多中心淋巴瘤犬的 CT 和 US 研究进行了回顾性评估。在有淋巴瘤的脾脏中，US 比 CT 更频繁地发现异常，而在有淋巴瘤的肝脏中，CT 比 US 更频繁地发现异常。这两种诊断影像学方法在发现结果上经常不一致，包括对器官正常或异常的影像学分类。
US 和 CT 在肝和脾淋巴瘤的影像学表现上经常不一致。本研究结果表明，无论肝脏和脾脏的 US 或 CT 表现如何，都建议对其进行细胞学评估，以检测淋巴瘤。
