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

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.

A study of the anatomical delamination of posterior renal fascia by CT / 实用放射学杂志

Objective To study the features of anatomical delamination of the posterior renal fascia in CT images.Methods Clinical datas and CT images of 85 patients with acute pancreatitis were collected,the anatomical delamination features of the adult posterior renal fascia were observed and recorded.Results (1) 23 cases showed anatomical delamination of the left posterior renal fascia, 9 cases showed anatomical delamination of the right posterior renal fascia, and 8 cases showed anatomical delamination of bilateral posterior renal fascia.(2) The features of anatomical delamination of the posterior renal fascia were detected in the whole posterior renal fascia or in the lateral part of the posterior renal fascia.Anatomical delamination was detected in the whole left posterior renal fascia in 6 cases, and was detected in the lateral part of the left posterior renal fascia in 17 cases.Anatomical delamination was detected in the whole right posterior renal fascia in 4 cases and in the lateral part of the right posterior renal fascia in 5 cases.Anatomical delamination of the whole part in the bilateral posterior renal fascia were detected in 4 cases and pure delamination of the lateral part in the both sides were 4 cases.Conclusion CT images can show the anatomical delamination of the posterior renal fascia which has two types.The anatomical delamination of bilateral posterior renal fascia is not always the same.
