The use of computed tomography in the evaluation of large multinodular goitres.

Le résumé fourni par la source

This study reports one unit's experience of the value of computed tomography (CT) in the evaluation of 24 patients with large cervical and retrosternal goitres. Of these patients, 17 were thought clinically to have symptoms of tracheal compression, but the CT demonstrated significant narrowing in only 12 cases. In the other five patients, surgery was deferred and other causes for their symptoms sought and treated. Seven patients were asymptomatic and CT failed to reveal any evidence of tracheal compression in six. In the remaining patient, however, CT revealed gross narrowing and urgent surgery was performed. When compared with CT, chest/thoracic inlet radiographs were misleading in 48% of patients, with tracheal narrowing being overestimated and underestimated. We conclude that CT gives useful information about tracheal compression in patients with large multinodular goitres, and is more accurate than chest/thoracic inlet radiographs.
