- W2380252495 abstract "Objective To determine the specific imaging criteria for differentiating tuberculosis from lymphoma in abdominal lymph nodes on contrast-enhanced multi-slice spiral CT. Methods Contrast-enhanced multi-slice spiral CT features in 55 patients with tuberculosis (n=20) and lymphoma (n=35) in abdominal lymph nodes were retrospectively assessed for the size, morphology, density, enhancement pattern and location. Results Ninety-five percent (19/20) of the tuberculosis showed peripheral enhancement, as compared with 17.2% (6/35) of lymphoma. Seventy percent (14/20) of the tuberculosis had a mass of multi-locular appearance compared with 8.6% (3/35) of lymphoma. Homogeneous attenuation was more commonly seen in lymphoma (29/35, 82.9%) than in tuberculosis (1/20, 5%). Tuberculosis and lymphoma often involved lesser omental, mesenteric, anterior pararenal, and upper paraaortic lymph nodes. In the determination of tuberculosis, sensitivity (95%), specificity (82.9%), accuracy (87.3%), positive predictive value (76%) and negative predictive value ((96.7%)) were obtained with peripheral enhancement. The specificity was increasing to 91.4% with multilocular appearance. In the determination of lymphoma using a combination of homogeneous attenuation and lower paraaortic lymph nodes, the outcome was sensitivity (82.9%), specificity (95%), accuracy (87.3%), positive predictive value (96.7%) and negative predictive value (76%). Conclusion The contrast-enhanced pattern and anatomic distribution of lymphadenopathy shown on contrast-enhanced multi-slice spiral CT can be useful in differentiating tuberculosis from lymphoma of abdominal lymph nodes." @default.
