Abstract:
Objective To investigate the radiological features of intracranial white epidermoid cysts(WECs).Methods A retro-spective analysis was conducted on the CT and MRI findings of 7 patients pathologically confirmed with WECs.All patients under-went plain CT and MRI scans,and six patients underwent enhanced MRI scans.Results All cases were solitary lesions,located in the right middle cranial fossa(2 cases),suprasellar area(2 cases),left cerebellopontine angle(1 case),right cerebellar vermis(1 case),and cerebellomedullary cistern(1 case),respectively.The lesions appeared oval or irregular in shape with clear boundaries and no perile-sional edema.The CT scans predominantly showed high density in 7 cases,with calcification in 1 case.On T1WI,7 cases exhibited high signal with mixed signals in some areas;6 cases showed primarily low signal on T2WI and fluid attenuated inversion recovery(FLAIR),with 1 case predominantly showed high signal;all 7 cases demonstrated low signal on diffusion weighted imaging(DWI).The margins of 1 lesion appeared"curly",and another exhibited a"swirl"pattern.5 cases had no enhancement,while 1 case had mild marginal enhancement.Conclusion Intracranial WECs has certain imaging characteristics.When a cystic lesion shows high density on CT,predominantly high signal on T1WI,and mostly no enhancement,considering the possibility of WECs.
