The infundibular recess (IR) is a cerebrospinal fluid (CSF) space in the third ventricle floor, and its function remains unclear. We retrospectively evaluated contrast enhancement of the normal IR using heavily T2-weighted 3D FLAIR. The enhancement of IR was the strongest on post-contrast images, followed by 4-h delayed post-contrast images. It was also stronger than that of other CSF spaces. This is the first study to report the enhancement of IR after an intravenous gadolinium injection. Evaluations of the enhancement of IR may clarify substance transport, such as gadolinium or hormones into the CSF.
