A well-defined, extra-axial lesion in the right quadrigeminal cistern. The lesion is T1 markely hyperintense and FLAIR hyperintense, T2 heterogeneous intensity. Importantly, fat-supressed T1 shows a drop in signal and a prominent chemical shift artefact on gradient echo. On DWI there is profound signal loss, rendering ADC uninterpretable. No mass effect, no hydrocephalus noted. The rest of the brain parenchyma appeared normal. Features were suggestive of lipoma thus no contrast scan was done.
