Chest x-ray showed a mediastinal tumor with dislocation of the trachea to the right. A Tc-99m pertechnetate scan showed irregular tracer uptake in an enlarged left lobe of the thyroid gland. Ultrasound confirmed the diagnosis of a nodular goiter with intrathoracic growth of the left lobe. A SPECT/CT scan of the mediastinum clearly showed that the soft tissue tumor was the left lobe of the thyroid gland, and not lymphatic metastases. © 2007 Lippincott Williams & Wilkins, Inc.
