Abstract
Objective To investigate the clinical characteristics of hypothyroidism manifested as pleural ef-fusion in order to analyze the causes of misdiagnosis. Methods The clinical data of 19 cases of pleural effusion caused by hypothyroidism from January 2005 to July 2016 were analyzed retrospectively. Results All 19 cases in this study were admitted to hospital due to pleural effusion and different degrees of dyspnea, including unilateral pleural effusion in 11 cases, bilateral effusion in 8, and pulmonary atelectasis with pleural effusion in 10. At initial visit, 16 out of 19 (84. 21％) cases were misdiagnosed, including heart failure (n=6), tuberculous pleuritis (n=5 ) , suspected malignant pleural effusion ( n=4 ) , and suspected empyema ( n=1 ) . With other causes of effusion excluded, improved relevant examinations revealed thyroid dysfunction, which contributed to the diagnosis of hypot-hyroidism. The effusions resolved in response to solely thyroid hormone replacement treatment, therefore, pleural ef-fusion induced by hypothyroidism was confirmed. No recurrence was reported at 1-year follow-up. Conclusion The clinical symptoms of hypothyroidism-induced pleural effusion are not specific, therefore, careful examinations and differential diagnosis are important to avoid the misdiagnosis.关键词
