1. Pituitary Apoplexy (뇌하수체 졸중)

뇌하수체는 간뇌의 시상하부 아래에 있으며, 시상하부의 지배를 받아 생명 유지에 필요한 호르몬을 분비한다. 뇌하수체 전엽에서는 성장호르몬(GH), 부신피질 자극 호르몬(ACTH), 갑상샘 자극 호르몬(TSH), 성선자극호르몬(GTH)을 분비하고, 뇌하수체 후엽에서는 옥시토신과 항이뇨호르몬을 분비한다. 뇌하수체 졸중은 뇌하수체 종양이 주변 뇌하수체 조직의 자발적 출혈 또는 경색으로 인해 종양의 갑작스런 증대가 일어나 발생하는 질병으로, 갑작스러운 두통 및 시력, 시야변화, 의식변화 등이 특정적인 증상으로 나타난다. 종양은 크기에 따라 미세선종과 대선종으로 나누고, 임상적인 관점에 따라 과분비성/기능성 선종, 비분비성/비기능성 선종으로 구분한다.

1. Pituitary Apoplexy (뇌하수체 졸중)

Pituitary apoplexy is a rare and potentially life-threatening condition that occurs when there is sudden bleeding or impaired blood supply to the pituitary gland, located at the base of the brain. This can lead to the rapid onset of severe headache, visual disturbances, and hormonal imbalances. Prompt recognition and treatment are crucial, as pituitary apoplexy can result in permanent pituitary dysfunction and even death if not managed appropriately. The pituitary gland is a small, but vital endocrine organ that produces hormones essential for regulating various bodily functions, including growth, metabolism, and stress response. Pituitary apoplexy is often triggered by a pre-existing pituitary adenoma, a non-cancerous tumor in the pituitary gland. The sudden bleeding or infarction (lack of blood supply) can cause the pituitary gland to swell, leading to compression of nearby structures and disruption of normal pituitary function. Symptoms of pituitary apoplexy typically include sudden, severe headache, visual disturbances (such as double vision or vision loss), nausea, vomiting, and altered mental status. Hormonal imbalances, such as low cortisol or thyroid hormone levels, may also occur. Immediate medical attention is required, as pituitary apoplexy can rapidly progress and lead to life-threatening complications, including pituitary insufficiency, cerebral infarction, and even death. Diagnosis is typically made through a combination of clinical symptoms, laboratory tests to assess pituitary hormone levels, and imaging studies, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. Treatment often involves high-dose corticosteroids to reduce inflammation and swelling, as well as hormone replacement therapy to address any hormonal deficiencies. In some cases, surgical decompression of the pituitary gland may be necessary to relieve pressure and restore blood flow. Overall, pituitary apoplexy is a rare but serious condition that requires prompt recognition and management to prevent potentially devastating consequences. Increased awareness and early intervention are crucial for improving outcomes and minimizing long-term complications for patients affected by this condition.
