Abstract
Isolated thyroid gland injury due to blunt neck trauma is uncommon and rarely complicated by thyroid storm in patients without known hyperthyroidism. The aim of this study was to report our experience on blunt thyroid gland injury followed by massive gland hemorrhage, acute airway obstruction, and symptoms of thyroid storm. Among 231 patients with neck trauma, four patients appeared with isolated thyroid gland injury. In two of them, the diagnosis of simultaneous thyrotoxic crisis was made on the basis of clinical findings and confirmed on emergency laboratory tests. The diagnosis of thyroid gland injury was supposed by the history and physical examination and established after neck exploration. Therapy was directed at stabilizing the patients by correcting the hyperthyroid state, followed by operative treatment. Left lobectomy and total thyroidectomy were performed and, along with postoperative medical measures, led to uneventful recovery. This study demonstrates that thyroid gland injury due to blunt neck trauma, although uncommon, may result in potentially life-threatening thyroid storm due to rupture of acini and liberation of thyroid hormones into the bloodstream. This may occur in patients without known hyperthyroidism.
