A Case of Substernal Goiter with Acromegaly

Abstract

A case of giant substernal goiter with acromegaly is reported. The patient, a 50-year-old male, had increasing exertional dyspnea and noticed an enlarging neck mass. A CT scan of the neck and chest suggested the presence of a substernal goiter extending inferiorly to the aortic arch and compressing the trachea. Median sternotomy was needed for removal of the goiter, which was completely extirpated, weighing 471g. The histological diagnosis was adenomatous goiter. The postoperative course was uneventful, and CT scan showed marked improvement of tracheal patency.
