Computed Tomography Scan Evidence of Bronchospasm and Its Resolution During Computed Tomography Coronary Angiogram in a Child With Kawasaki Disease: A Case Report.

Bronchospasm in children is common; however, due to its sudden nature, radiographic correlation is uncommon. We planned a computed tomography (CT) coronary angiogram for a 5-year-old child for evaluation of Kawasaki disease. The child started to desaturate during the CT scanning after intravenous contrast injection under conscious sedation. CT scan documented spasm of trachea and bronchi, as well as crowding of ribs and elevated diaphragm during the event. Repeat CT scan documented well-aerated lung fields. The development of acute bronchospasm under anesthesia results in definite changes in the CT scan of the thoracic cavity as evidenced by this incident.
