The tuber cinereum and left mammillary body show a small solid mass lesion measuring about 5 x10 mm with hyperintense T1 and T2 / FLAIR signals. The lesion is suppressed on the fat-saturated sequence (T2 fat sat, T1 C+ fat sat) with no significant post-contrast enhancement.
Normal right mammillary body.
The remainder of the brain is unremarkable.
Case Discussion
MRI features were consistent with a small, fat equivalent signal (high on T1/T2) mass lesion with attenuation on T1 fat sat sequences with contiguous with the tuber cinereum diagnostic of tuber cinereum lipoma.
The floor of the 3rd ventricle from the pituitary stalk to the mammillary body is called the tuber cinereum; it should be smooth.
