Thyroid Cancer Presenting as Aspiration Pneumonia: A Tale of Retrosternal Goiters

Abnormal enlargement of the thyroid gland is called goiter. Structurally, it can be nodular or diffuse. Usually, it presents as an anterior cervical mass; however, less commonly, it presents as a retrosternal mass causing symptoms of compression on the surrounding structures. Most patients with goiter are asymptomatic due to the euthyroid nature of the disease. However, sometimes they can be hypo or hyperthyroid depending on the etiology of the goiter. Here, we present the case of a patient without any previously known goiter who presented to the hospital with shortness of breath and was found to have hypoxic respiratory failure as his first noticed sign of thyroid disease. Diagnostic workup revealed retrosternal goiter causing compression effect on the esophagus and trachea resulting in dysphagia and aspiration. The patient was treated with feeding tube placement, followed by surgical resection of the mediastinal mass.
