Syncope in a patient with spontaneous hemorrhage into a thyroid nodule.

概要
BACKGROUND
Spontaneous hemorrhage into a thyroid nodule occurs exceedingly rare and rarely a neck hematoma can develop. We report a case of syncope due to spontaneous hemorrhage into a thyroid nodule during anticoagulant and antithrombotic therapy.
METHODS
A 64-year-old man was transferred to the emergency department of our hospital because of syncope. His physical examination revealed a 7 x 5 cm hard and painless mass at the left neck region. The neck MRI confirmed a heterogeneous, hyperintense mass in the left lobe of thyroid compressing the trachea and left common carotid artery, internal jugular vein, and vagus nerve bundle. He did not require a surgery in the follow-up. As the hematoma underwent subtotal shrinkage, he remained well without syncope.
CONCLUSIONS
Hemorrhage into a thyroid nodule should always be considered in patients presenting with neurally mediated syncope.
