Match each clinical presentation of an endocrine lesion with its most appropriate diagnostic or surgical management step.
- A 45-year-old woman with a 2-cm thyroid nodule, decreased TSH, elevated free T4, and increased uptake on a radionuclide scan.Surgical resection or radioactive iodine ablation without the need for fine-needle aspiration.
- A 55-year-old man with a 1.5-cm thyroid nodule, normal TSH, and fine-needle aspiration demonstrating intranuclear inclusions and grooved nuclei.Thyroid lobectomy or total thyroidectomy depending on patient factors.
- A 60-year-old woman with asymptomatic hypercalcemia of 11.2 mg/dL, elevated intact parathyroid hormone, and a 24-hour urine calcium of 350 mg.Preoperative localization imaging followed by minimally invasive surgical resection.
- A 40-year-old man with an incidentally discovered 5-cm adrenal mass and significantly elevated 24-hour urine fractionated metanephrines.Preoperative alpha-adrenergic blockade for 10-14 days followed by surgical resection.
Cevap
The correct matches align each specific endocrine pathology (toxic adenoma, papillary thyroid carcinoma, primary hyperparathyroidism, and pheochromocytoma) with its standard diagnostic and perioperative surgical management.
Each matching pair appropriately links the clinical endocrine pathology with the standard of care. Toxic adenomas do not require FNA and are managed definitively. Papillary thyroid carcinomas require surgical excision. Primary hyperparathyroidism is treated with parathyroidectomy after localization. Pheochromocytomas require mandatory alpha-blockade to prevent life-threatening intraoperative hemodynamic instability.
