Craniopharyngiomas are known for causing vision and neuroendocrine deficits due to involvement of which structure?

Craniopharyngiomas arise in the sellar/suprasellar region, right where the pituitary gland sits and just above the optic chiasm. This location means the tumor often compresses or involves the pituitary and the hypothalamic-pituitary axis, leading to neuroendocrine deficits such as hypopituitarism, while also pressing on the optic chiasm to cause vision problems. Because of this dual impact from the pituitary region, involvement of the pituitary gland best explains both the vision and endocrine symptoms. Involvement of the optic radiations would mainly affect vision without endocrine issues, and the third ventricle or carotid arteries don’t account for the characteristic neuroendocrine dysfunction seen with these tumors.
