발살바 법 이후에 발생한 자발적 갑상선 출혈

Spontaneous thyroid hemorrhage is a rare cause of acute neck swelling. But it is self-limiting in most cases. Symptoms of thyroid hemorrhage are often subtle or not present on initial exam. But it can be rapidly expanding hematoma resulting in airway compromise. We have reported the case who a 21-year old healthy young woman with slowly expanding thyroid hemorrhage without trauma history. There were mild dyspena and swelling of the neck gradually increased. So she underwent hemithyroidectomy for definitive treatment. There had not been reported in the literature regarding spontaneous thyroid hemorrhage in a young healthy female patient with valasalva maneuver. Decision making is based on the patients’s vital signs, symptoms, and the findings on a contrast enhanced computered tomography of the neck. (J Clinical Otolaryngol 2017;28:116-119)
