Analysis of multi-slice spiral CT features of mediastinal bronchial cysts
摘要
Abstract
Objective To analyze the multi-slice spiral CT(MSCT)imaging features of mediastinal bronchial cysts(MBC)to guide clinical diagnosis and differential diagnosis.Methods A retrospective analysis was conducted on the MSCT features of 31 ca-ses of MBC with complete clinical data and confirmed by surgery and pathology.The location,morphology,density,margin,cyst wall,degree of enhancement,etc.of the lesions in the mediastinum were observed and classified,and compared with previous literatures.Results For the first time,it was found that the anterior mediastinum was a new predominant distribution area of MBC(13/31,41.9%),and the location was significantly correlated with the density(P=0.032),with a low-density proportion of 53.8%(OR=4.08).Three-dimensional morphological analysis showed that 96.8%(30/31)of the cases had a characteristic"ellipsoid-like"mor-phology,and 48.4%(15/31)of the cases showed a"ellipsoid-like-parallel vascular sign"composite sign,with the long axis con-sistent with the course of adjacent vessels.There was no enhancement on enhanced scanning.Conclusions The combination of fea-tures such as anatomical-density association,ellipsoid morphological index and parallel vascular sign can improve the diagnostic accura-cy of MBC.关键词
