Abstract:
Objective To analyze the imaging manifestations of bronchogenic cyst(BC)and summarize the causes of misdiagno-sis,in order to improve the diagnostic and differential diagnostic level for BC.Methods A retrospective analysis was performed on the imaging data of 84 patients surgically and pathologically confirmed BC.All patients underwent plain CT scans,with 66 cases further received contrast-enhanced CT scans and other 12 cases underwent plain MRI scans,6 of which underwent contrast-enhanced MRI scans.Results A1184 cases presented as solitary lesions,comprising mediastinal(n=71),intrapulmonary(n=4)and ectopic(n=9)types.The lesions were predominantly round(69 cases),flattened(5 cases),or irregular(10 cases)in shape.Gas was observed in 4 cases,with one showed air-fluid level.66 cases exhibited soft tissue density,14 cases showed water-like density,and other 4 cases displayed high density.Calcifications,either punctate or arcuate in shape,were found on the lesion margins in 2 cases.Among the 66 cases that underwent contrast-enhanced CT scans,11 showed mild enhancement,with 5 cases only mild annular enhancement of the cyst wall.MRI findings in 12 cases revealed iso-T1 signals and long or slightly long T2 signals,with no enhancement detected on contrast-enhanced scans.The misdiagnosis rate for mediastinal BC was 76.1％(54/71),while all intrapulmonary and ectopic BC were misdi-agnosed preoperatively.Conclusion BC shares similar imaging manifestations with various other diseases,resulting in a high misdi-agnosis rate.Integrating clinical symptoms with multimodal imaging features and enhancing diagnostic awareness and experience are essential for improving the diagnostic accuracy of BC.
