Pituitary apoplexy is a medical emergency caused by sudden hemorrhage or infarction of the pituitary gland, often occurring in people with pre-existing pituitary tumors. It usually presents with the following symptoms:
- Headache: A sudden and severe headache is commonly observed due to the rapid expansion of the pituitary gland.
- Vomiting: Nausea and vomiting are frequent due to increased intracranial pressure and associated stress response.
- Hypertension: Elevated blood pressure can occur as part of the body's stress response to the acute event, contributing to the clinical picture.
Among the given options, Hypotension is not typically seen in pituitary apoplexy. Patients are more likely to experience hypertension rather than hypotension due to the acute stress and possible adrenal dysfunction. Therefore, the correct answer to the question is Hypotension.
