Characteristic appearance of an epidermoid cyst in the cerebellopontine angle. The lesion has a similar signal intensity to CSF on both T1 and T2 weighted sequences but is 'dirty' on FLAIR. The diagnosis is confirmed on DWI which demonstrates very bright signal with intermediate ADC values similar to brain parenchyma.
