Abstract

Abstract:

Objective　To evaluate multiple-slice computed tomographic (MSCT) features of colonic carcinoma involving the transverse mesocolon (TM) and its anatomic basis. Methods　The MSCT images of 28 cases with colonic carcinoma were compared with surgical and pathological findings, retrospectively. Results　Among the 28 cases, the sensitivity, specificity and accuracy of judging TM infiltration by mass forming, nodular and wedge-shaped shadow, short bars and increased fat density in the TM were 16.7%，61.1%，5.6%，33.3%; 100%，80%，30%，50%; 46.4%，67.9%，14.3 %，39.3%. Five cases showed enlarged lymph nodes in the TM.　Conclusion　The involvement of TM by colonic carcinoma can show some special CT features. MSCT images are helpful for preoperative imaging evaluation of TM involvement and lymphatic spread.
