title: Case report: lingual thyroid, a cause of neonatal stridor.
abstract: Stridor implies partial airway obstruction, resulting from intrinsic or extrinsic abnormalities of the upper respiratory tract. In a neonate whose airway is small, soft and easily occluded this may be potentially life threatening. Its immediate diagnosis with prompt therapy is a rewarding challenge. When stridor occurs in a neonate with congenital hypothyroidism, surgically amenable cause of obstruction due to an ectopic thyroid or thyroglossal cyst has to be seriously considered. We report a case of neonatal stridor caused by a lingual thyroid, and discuss the imaging approach.
