A RARE CASE OF GRAVES' THYROTOXICOSIS WITH CONCOMITANT PULMONARY ALVEOLAR PROTEINOSIS
1Presbyterian Medical Center, Division of Endocrinology, Department of Internal Medicine, Jeonju, Korea.
Background:
Graves' disease results in various clinical cardio-pulmonary manifestations such as tachycardia, atrial fibrillation, and pulmonary edema.
Clinical Case:
A 62-year-old woman presented with palpitations and dyspnea. Laboratory and radiologic examination revealed markedly elevated free T4 (4.79 ng/dL), T3 (4.42 ng/mL), lowered TSH (0.01 uIU/mL), atrial fibrillation and multifocal lung haziness. She was initially diagnosed with atrial fibrillation with pulmonary edema, which subsequently changed to pulmonary alveolar proteinosis by further evaluations such as computed tomography and bronchoscopic biopsy.
Conclusion:
Pulmonary alveolar proteinosis is a rare lung disease. Clinicians should carefully assess lung lesions in thyrotoxicosis patients as they can be easily mistaken for pulmonary edema in clinical practice.

Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
