Fig. 11From: Magnetic resonance imaging of pineal region tumoursPineal lipoma. Sagittal T1-weighted image (a) shows a well-circumscribed high signal lesion (arrow) involving the dorsal portion of the tectal plate extending into the pineal recess. The signal of this lesion is nulled on the axial fat-suppressed T1-weighted image (b) confirming the diagnosis of lipomaBack to article page
