CT manifestations of acute pancreatitis involving the bridging septa and its correlation with EPICT / 实用医学杂志

ABSTRACT

Objective To study the computed tomography(CT)manifestations of involvement of bridging septa in the perirenal space(BSPS)during acute pancreatitis(AP)and its correlation with extrapancreatic inflam-mation on abdominal computed tomography(EPICT)score. Methods 106 patients with acute pancreatitis were included in this study. Emphasis was placed on CT findings of BSPS and the EPICT score in all the patients. Results The EPICT score was 4 to 7 in 67 patients,and the EPICT score was 0 to 3 in 39 patients. BSPS involve-ment was shown in all the patients. The left or right BSPS involved in 102 patients and 98 patients,respectively. Thickening of the BSPS was shown as strip shadow with slightly higher density and hazy border;fluid collection of the BSPS was shown as liquid density with hazy border. The involvement of BSPS showed a statistically significant association with the EPICT score in the AP patients(r=0. 703,P<0.01). Conclusion BSPS involved by acute pancreatitis is shown as a strip shadow with slightly higher density or as liquid density with hazy border on CT images, reflecting the severity of the acute pancreatitis.
