“…In humans, lymphomas demonstrate a “fish flesh” appearance on gross specimen examination, with necrosis being infrequently present . Therefore, homogeneous enhancement is more commonly seen in lymphomas, and 17% of lymphomas demonstrate heterogeneous enhancement . In this study, enlarged lymph nodes of the lymphoma cases and lymph nodes of adenocarcinoma cases showed similar enhancement patterns.…”

In humans, computed tomography (CT) is a widely performed technique for the diagnosis and staging of gastric tumors. The purpose of this retrospective case series study was to describe CT findings in a group of dogs with confirmed gastric tumors. For each included dog, the following CT parameters were recorded: gastric tumor location, tumor shape, gastric involvement pattern, tumor enhancement pattern in early and late phases, presence and location of lymphadenopathy, gastric tumor attenuation values, attenuation values of enlarged lymph nodes, maximum short-axis diameter (mm) of enlarged lymph node, maximum long-axis diameter (mm) of enlarged lymph node, and short-axis diameter to long-axis diameter ratio (short axis/long axis). A total of 16 dogs met inclusion criteria and had the following final diagnoses: five lymphoma, six adenocarcinoma, three inflammatory polyps, and two leiomyoma. In the early- and delayed-phase postcontrast images, the mean CT attenuation value for lymphoma was lower than that of other gastric tumors. Lymphadenopathy was widespread in lymphomas and regional in adenocarcinomas. Lymphadenopathy was not detected in leiomyomas. Lymph node measurements in lymphoma were larger than lymph node measurements in adenocarcinoma. Although there were overlapping findings for the different types of gastric tumors, contrast-enhanced CT provided helpful information for characterizing gastric tumors based on the following criteria: early and late enhancement patterns, the site of origin of the mass lesion, and extent of local invasion and distant metastases. Lymphoma should be considered for canine gastric tumors with low mean attenuation values during early- and delayed-phase postcontrast images, and widespread, bulky, and rounded lymphadenopathy.

“…Differentiation of malignant from benign mediastinal lymphadenopathy in children is essential for treatment planning and for prediction of prognosis [1,2]. CT scanning is commonly used for assessment of mediastinal nodes in children, but it cannot accurately differentiate malignant from inflammatory nodes [3][4][5]. Recently, dual-energy CT [6,7] and CT perfusion [8] have been used for assessment of lymph nodes in different regions of the body, but they are associated with exposure of children to radiation.…”
