What is the typical presentation of pituitary apoplexy?

• A. Acute severe headache with visual disturbance and ophthalmoplegia due to hemorrhage into a pituitary adenoma.
• B. Gradual onset of hearing loss.
• C. Chronic headaches with neck stiffness.
• D. Transient ischemic attack.

Answer: (A)

Pituitary apoplexy presents as an abrupt, severe headache with rapid visual changes and eye movement problems caused by hemorrhage or infarction within a pituitary adenoma. The sudden expansion within the sella compresses the optic chiasm, producing acute visual disturbances (often decreased acuity and visual field loss, such as bitemporal fields) and can affect the oculomotor nerves, leading to ophthalmoplegia and diplopia. Patients may also have nausea, vomiting, altered mental status, and signs of acute pituitary hormone deficiency (notably cortisol deficiency), which can cause hypotension. Imaging reveals a hemorrhagic or necrotic pituitary mass. This picture specifically reflects the acute hemorrhagic event in the pituitary, unlike gradual hearing loss, chronic headaches with neck stiffness, or a transient ischemic attack, which do not describe this sudden hemorrhagic and neuro-ophthalmic process.
