The question remaining is why a tumor that synthesizes ACTH does not cause the associated clinical syndrome.

With more severe compression or direct invasion of the optic gonadotroh, decreased visual acuity may occur. Severe primary hypothyroidism can cause mild ovarian hyperstimulation syndrome 4553 — 63 and may lead to pituitary hyperplasia mimicking a macroadenoma; achievement of euthyroidism leads to a resolution of these manifestations.
