Manifestation of Intestinal Tuberculosis on Multi-slice Computed Tomography Enteroclysis / 中山大学学报(医学科学版)

ABSTRACT

[Objective] To summarize image manifestations in intestinal tuberculosis (ITB) examined by multi-slice computed tomography enteroclysis (MSCT) and evaluate the diagnostic value of MSCTE in ITB,[Methods] The imaging findings were retrospectively analyzed in 15 cases of ITB that were confirmed by endoscopy or postoperative pathologic examination,including the location,number,shape,edge,surrounding tissue alterations of ITB and other associated changes in the peritoneum,mesentery and solid abdominal organs,and compared with endoscopy and pathology.[Results] In 15 patients,ileocecum was involved in 13 cases (87％),4 cases (27％) showed multi-segmental symmetric intestinal mural thickening,9 patients (60％) showed solid masses,1 case (7％) showed multi-segmental symmetric intestinal mural thickening and solid masses,1 case (7％) showed homogenous enhanced masses and perforation,12 cases (86％) showed enlarged lymph nodes (LNs) with rim enhancement,and 2 cases (13％) showed the comb sign of enhanced mesenteric vessels.Based on enhancement pattern of MSCTE,ITB was divided into three typeshomogenous enhancement type (n=5);target sign type (n=2);caseous necrosis type (n=2).[Conclusion] The imaging features of ITB are diverse.MSCTE can clearly display the shape of intestinal mucosa,the alterations of intestinal wall and the relationship between lesion and adjacent tissues,which provides valuable information for the clinic diagnosis of ITB.
