A craniopharyngioma, common in children, is a congenital benign tumor that grows in the pituitary fossa at the base of the skull.
It grows slowly, but it can compress and invade the pituitary gland and hypothalamus, impairing their function and causing abnormal hormone secretion.
Because of its proximity to the optic nerve, it also frequently causes vision problems.
However, what caught Yan Feifan's attention most about this type of tumor was its significant hardness and propensity for calcification.
The incidence of calcification in childhood craniopharyngiomas can be as high as 93%, and nearly all craniopharyngiomas have calcified lesions.
A tumor with these properties is not very suitable for shrinking via absolute ethanol injection, which works by dehydrating and denaturing the tumor's proteins.
Qiu Ge could see Yan Feifan's concern and said softly, "If the tumor were that easy to remove, the patient's family wouldn't be offering a hefty ten-million incentive."
