Inferior thyroid artery pseudoaneurysm caused by blunt trauma.

Injury to the inferior thyroid artery (ITA) is an extremely rare complication of blunt neck trauma. The subtle initial clinical presentation and the potential life-threatening sequelae make it a diagnostic and therapeutic challenge. We report a case of an ITA pseudoaneurysm caused by seat-belt injury. Imaging findings and successful treatment with coil embolization are described. The role of noninvasive imaging techniques in establishing the diagnosis is emphasized.
