Abstract:
Objective To summarize the features of multi-slice spiral computed tomography (MSCT) examination of acute primary epiploic appendagitis,and investigate the clinical value of MSCT.Methods The clinical data of 19 patients with acute primary epiploic appendagitis who were admitted to the Yangzhou No.1 Hospital from December 2009 to March 2014 were retrospectively analyzed.All the patients received MSCT examination,and the data were transported to the work station for multiplanar reconstruction.The location,shape,size,density,peripheral performance and peritoneal thickening were observed.Results The foci of the 19 patients were located adjacent to the colon.One focus was adjacent to the cecum,4 were adjacent to the ascending colon,1 was adjacent to the hepatic flexure of the colon,6 were adjacent to the descending colon,and 7 were adjacent to the sigmoid colon.The shapes of the foci were similar to the oval or ring in 14 cases and similar to the flame in 5 cases.The diameters of the foci were 0.8-3.7 cm.The results of CT plain scan showed that the density of the foci was similar to that of the fat,and the CT value was-101--34 HU.The central density of the foci was lower,while the limbic density was higher.The results of CT enhanced scan showed a ring-like enhancement region in the foci,and the lesion was surrounded by slightly high-density inflammation.Point or linear slightly high-density shadows were detected at the center of the foci in 9 patients.The peritoneum was locally thickened in 14 patients.The colonic wall was locally thickened in 1 patient,and the pelvic effusion was detected in 5 patients.The results of CT reexamination of 4 patients showed that the inflammatory regions were reduced or disappeared,the mass shrank,nodulized or calcified.Conclusions MSCT examination can provide a specific features of primary epiploic appendagitis.It could accurately diagnose acute primary epiploic appendagitis when combined with multiplanar reconstruction.
