Usefulness of SPECT/CT in the Diagnosis of Intrathoracic Goiter versus Metastases From Cancer of the BreastDümcke, Christine W., MD; Madsen, Jan L., MD, DMScClinical Nuclear Medicine: February 2007 - Volume 32 - Issue 2 - p 156-159 doi: 10.1097/01.rlu.0000252175.44833.49 Interesting Image Buy Abstract Author InformationAuthors Article MetricsMetrics A 77-year-old woman was referred because of local reoccurrence of cancer of the breast. 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.
