Substernal goiter is overall an uncommon disease. Obstructive symptoms can occasionally develop in older patients with a longstanding history of goiter. Here, we describe a rare case of pulmonary embolism presenting as a complication of benign substernal goiter in a young patient without preceding recognized thyroid disease. After three separate biopsies, surgical resection was eventually performed, with pathology confirming the diagnosis of multinodular thyroid with cystic changes. Four months after the surgery, a CT angiogram of the chest was performed, which showed resolution of bilateral pulmonary emboli.
