MSCT findings and clinical diagnostic value of acute primary epiploic appendagitis / 实用放射学杂志

ABSTRACT

Objective To analyze the MSCT characteristics in patients with acute primary epiploic appendagitis(PEA)and to explore the clinical diagnostic value.Methods The complete MSCT examination data,surgical pathology and follow-up results of 1 2 patients with acute PEA in our hospital were analyzed retrospectively.Results In 1 2 cases of acute PEA,the locations of lesion werebeside the sigmoid colon in 5 cases,beside the descending colon in 4 cases,beside the ascending colon in 2 cases and beside the cecum in 1 case;the lesion morphologies wereround or oval in 9 cases,lobulated changes in 3 cases;the lesions were all lipid density;1 2 cases showed a ring-shaped high-density shadow on the edge;1 1 cases of lesions showed high-density shadow in the center,1 case of lesion showed no high density shadow in the center;in 8 cases,there were stripe-shaped high-density exudation shadow around the fat space;only 2 lesions showed thickening of the adjacent colon wall;and in two cases,the edges of lesions in the enhanced scanning showed annular enhancement.Conclusion Acute PEA has characteristic features in the examination of MSCT (oval or ring-like fat density mass,central punctate high-density shadow,high-density marginal ring sign with or without peripheral inflammatory exudation changes). Combining the multiplanar reconstruction(MPR),it can clarify the diagnosis and show conditions of the surrounding tissue,providing important value for clinical treatment.
