Case Discussion
The clinical context and the MRI features in a patient known for pituitary macroadenoma are highly suggestive of pituitary apoplexy.
Pituitary apoplexy is an acute clinical condition caused by either hemorrhagic or non-hemorrhagic necrosis of the pituitary gland.
An existing pituitary macroadenoma is present in 60-90% but has been reported in healthy pituitary glands in a few isolated cases.
