Quadrigeminal plate lipoma

Case contributed by Dr Gagandeep Choudhary
Modality: MRI

A mass in the quadrigeminal plate cistern, just below the pineal gland has high T1 and T2 signal and attenuates on fat saturated T1 C+ sequence. Additionally it demonstrates prominent chemical shift artefact on the sagittal T2 and gradient echo sequences. Features consistent with a lipoma. 

Case Discussion

Appearances are typical of an intracranial lipoma. If fat saturated sequences are not available, then presence of chemical shift artefact is helpful in confirming the mass is fatty.
