Figure 1

Etiological classification of CDI. Craniopharyngioma: (a) T1WI image showed tumor (white arrowhead); (b) 3D examination showed clearer uniform tumor (white arrow). Intracranial germinoma: (c) T1WI image showed that the upper edge of the pituitary was uplifted, and the posterior high signal was not shown, and the pituitary stalk was thickened (white arrow); (d) the enhanced examination showed that the pituitary stalk and pineal gland were uniformly nodular (white arrows). Langerhans cell histiocytosis: (e) T1WI showed a thickening of the pituitary stalk, showing T1 and other T2 signals, clear edges, pressure in the third ventricle, disappearance of the funnel crypt, slightly increased pressure in the optic chiasm, and no signal in the posterior pituitary; (f) the enhanced scan showed mild even enhancement of the mass, and the anterior pituitary was less clear.
