Diagnosis value of spiral CT in leiomyosarcoma of abdomen / 肿瘤研究与临床

ABSTRACT

Objective To evaluate the diagnosis value of spiral CT in leiomyosarcoma of abdomen.Methods Both plain and enhanced CT fingdings in 12 cases with pathologic-proved leiomyosarcoma of abdomen were respectively analyzed.Results In all of 12 cases,1 case occurred in colon,1 case in rectum,1 case in small intestine,5 cases in mesentery,4 cases in retroperitoneum,CT positioning accuracy rate was 91.7 ％ (11/12).The volume was comparatively large,the average diameter was 6 cm.The density were uneven,nodosity or lamellar necrosis were found.Delay enhacement were occurred in lower density part in most part of cases (9/12).Conclusion The localization of spiral CT is comparatively accurate to the leiomyosarcoma of abdomen,some characteristics are found in CT image,but the final diagnosis depends on immunohistochemistry.
