Tuber Cinereum Diverticula in a 28-Month-Old with Xq21 Deletion Syndrome
Figure 5
(a) Parasagittal SPGR T1WI (repetition time msec/echo time msec/inversion time msec, 8/3/450) from a 3-year-old male depicting normal brain anatomy. The lateral portion of the hypothalamic tuber cinereum has a straight outer contour (thick arrow), in contrast to the diverticulum shown in Figure 2. The normal mammillary body (curved arrow) and forniceal column (thin arrow) are partially visible. (b) Axial T2WI (repetition time msec/echo time msec, 3200/111) from a 3-year-old male showing normal hypothalamic anatomy. Hypothalami are visible near midline, marginating the 3rd ventricle (straight arrows). The inner margins of the hypothalami are uniformly straight apart from the rounded contour of the mammillary bodies (curved arrows).
