Suprasellar cistern lipoma

Discussion:

MRI features are consistent with a fat-containing intracranial lesion at the interpeduncular cistern projecting into the suprasellar cistern with no enhancement and lobulated contour consistent with intracranial lipoma. Considering the anatomical location, features are in keeping with tuber cinereum lipoma (hypothalamic lipoma). Differential diagnosis includes tuber cinerium hamartoma but usually of no fat content, presenting in children with precocious puberty.
