Patient Data

Age: 20 years
Gender: Male

An epidermoid cyst follows CSF on T2W, T1W images (hyperintense on T2W, hypointense on T1W images). It is isointense (higher than CSF) on FLAIR. Diffusion-weighted imaging is important to differentiate an epidermoid cyst from an arachnoid cyst. Epidermoid cyst shows restricted diffusion (bright on DWI, intermediate on ADC) whereas arachnoid cyst do not.
