What Is Cushing's Disease?
5. Cushing’s Disease Symptoms in Patients with Large Tumors
In the rare instance that a person has a large tumor, other complications can occur because the tumor compresses surrounding structures. Loss of peripheral vision happens when the tumor grows up into the brain cavity and presses on the optic nerves where they cross. If the growth instead extends forward and compresses on an optic nerve at that location, blurry vision results.
When the pituitary gland itself is pressed upon, hormone production potentially diminishes for sex hormones or the follicle-stimulating hormone. It might also lead to a loss of menstruation in women due to an increase in prolactin.
