What do we mean by an Apoplexy

An Apoplexy when a pituitary tumor spontaneously hemorrhages or bleeds or when it outgrows its blood supply. This loss of blood supply can cause tumor cell death, bleeding and acute tumor swelling. The relatively sudden change in tumor size causes compression of the normal pituitary gland, the optic nerves and the nerves that control eye movements.
All types of pituitary adenomas can be associated with apoplexy, particularly larger tumors2 or macroadenomas. There are no clear predisposing factors2 for developing pituitary apoplexy, although it has been associated with a wide range of disorders and treatment side effects.
Symptoms: Symptoms often include headache, nausea, visual loss and double vision. If bleeding extends into the cerebrospinal fluid spaces, severe headache, neck stiffness and fever may occur. Most patients also have undiagnosed hormone insufficiency.
Apoplexy is bleeding into an organ or loss of blood flow to an organ.
For example: adrenal apoplexy is bleeding into the adrenal glands, pituitary apoplexy is bleeding into the pituitary gland, and so on.
When the word apoplexy with no organ specified is used alone, it often refers to stroke symptoms that occur suddenly. Such symptoms can be caused by bleeding into the brain or by a blood clot in a brain blood vessel. Conditions such as subarachnoid hemorrhage or stroke are sometimes called apoplexy.
Functional apoplexy is when a person appears to be having stroke-like symptoms but there is no brain abnormality.
