Epidermoid cyst. On a T2-weighted image (a) a lesion is seen in the left cerebellopontine and prepontine cistern with a slithgly higher signal intensity than CSF. Note vessels running through the lesion. On T1 (b) a slightly increased signal intensity is seen, which is sometimes referred to as “dirty CSF”. The incomplete supression of signal on FLAIR (c) and the diffusion restriction (d) confirm the diagnosis of an epidermoid cyst
