[Goiter: a rare cause of childhood dyspnea].

We report the case of a patient who presented dyspnea due to a large intrathoracic goiter. This patient had congenital hypothyroidism due to thyroid enzyme deficiency. He came to a pediatric emergency department for dyspnea. At home, he had inspiratory and expiratory dyspnea with a stridor. No signs of respiratory distress were observed. The neck was deformed by a large goiter. The patient indicated that he did not follow the recommended L-thyroxine treatment. Chest and neck radiography showed tracheal compression. A cervical CT scan showed a 60% reduction of the tracheal caliber. To our knowledge, only one case report of goiter with tracheal compression due to congenital hypothyroidism has been reported in the literature. In the case of retrosternal goiter, dyspnea is more common than respiratory distress. Absence of tachypnea or use of accessory muscles does not exclude an anatomic compression. In the case of dyspnea, the search for a goiter is recommended.
