Abstract:
We present a rare case of acute thyrotoxicosis in a man with horse-induced neck trauma. A 60-year-old man presented to our emergency department with a head and neck injury caused by a horse kick. Computed tomography revealed a hematoma in the right thyroid gland. Ultrasonography of the neck revealed a 1.4 cm sized heterogenous hypoechoic lesion with an irregular margin in the right lower pole, suggestive of a thyroid hematoma. A thyroid function test revealed elevated free thyroxine and free triiodothyronine levels and suppressed thyrotropin levels. A Tc-99m thyroid scan showed a mild diffuse decreased uptake in the thyroid gland, especially in the right lower pole. We monitored the thyroid function test results, which took 2 months to recover to the normal range. This case indicates that awareness of thyroid dysfunction and monitoring of thyroid function are vital in patients with neck trauma.
