Abstract:
Objective To study the MR imaging features of intracranial epidermal cyst.Methods 18 cases(include 7 male,11 female) epidermal cyst pathology confirmed were analysed.Results The epidermal cyst usually exhibited heterogeneously low signal intensity on T 1WI(88.9%),and only 2 patients showed high signal intensity on T 1WI(11.1%).After contrast medium enhancement 16 cases had no obvious enhancement,only 2 patients had rim light enhancement .Conclusion Typical epidermal cyst commonly show heterogenously low signal intensity on T 1WI. A typcal epidermal cyst has high signal intensity on T 1WI.Differential diagnosis shoud be consider on these kind of epidermal cyst.
