(A and B) Schematic drawing of Hypothalamic stalk CPs, which originate from the junction of hypothalamus and stalk, and can grow along the hypothalamus upward, or along the stalk downward, or both directions. The most common growth pattern is on both directions, and between the two parts, there is a circumferential band surrounded by tight adherence of the hypothalamic remnants (B). (C and D) Intraoperative photographs showing that a large defect at the left side of the third ventricle floor was observed after completely resection of a Hypothalamic stalk CP. The stalk was pushed to contralateral side and connected to the remnants of contralateral hypothalamus. Ps, pituitary stalk; 3rd V., the third ventricle, L.Ht, left hypothalamus, R.Ht, right hypothalamus.
