Imaging analysis of meningeal involvement in otogenic lesions
摘要
Abstract
Objective:To analyze the imaging features of meningitis involved by otogenic lesions to improve the imaging diagnostic efficiency of ear lesions.Investigate the risk factors of meningitis caused by ear cholesteatoma.Methods:Imaging data of patients who underwent ear magnetic resonance plain scan plus diffusion and enhancement examination and CT plain scan of temporal bone in our hospital from January 2020 to January 2023 were collected.Imaging and clinical information of patients with otogenetic diseases with meningeal involvement and postoperative pathology were collected and retrospectively an-alyzed,and imaging characteristics of meningeal involvement were retrospectively analyzed.At the same time,the imaging and clinical information of patients with middle ear cholesteatoma with destruction of the tympanic roof on CT but no meningeal involvement on MRI were collected,and the risk factors of meningitis caused by middle ear cholesteatoma were retrospectively analyzed.Results:The neoplastic lesions of the ear involving the meninges are mainly squamous cell carcinomas.There were statistical differences in coronal diameter of thickened and enhanced meninges∕maximum coronal diameter of bone destruction(Rc),sagittal diameter of thickened and enhanced meninges∕maximum sagittal diameter of bone destruction(Rs)and maximum thickness between non-tumor group and malignant tumor group,with Z values of 2.05,2.15,3.09,P<0.05,respectively.As for ear cholesteatoma patients,there were no significant differences in gender and smoking history between the meningeal en-hancement group and non-meningeal enhancement group,χ2 values were 0.50 and 0.42,P>0.05,respectively.There was no significant difference in the mean diameter of cholesteatoma(Rm)and the mean diameterof tympanical roof destruction(Dm)(Z= 1.13,0.89 respectively,P>0.05).The granulation tissue thickness of the damaged tympanic roof was significantly different be-tween the two groups(Z=5.94,P<0.001).Conclusion:The imaging manifestations of meningeal thickening and enhancement caused by malignant tumors and non-neoplastic ear lesions are different.The former has greater membrane thickening,but the range of membrane enhancement relative to the extent of bone destruction was smaller than the latter.The presence of granu-lation tissue around the cholesteatoma in the destruction place of the tympanic roof is a risk factor for meningeal involvement in patients with middle ear cholestatoma.关键词
