From the case:
Quadrigeminal plate lipoma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/11418/annotated_viewer_json?lang=us"}
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 artifact 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 artifact is helpful in confirming the mass is fatty.
