Thyroid nodule seen on chest CT. Weight loss. RIGHT LOBE MEASUREMENTS: Best measurement of 6.2 x 2.0 x 3.1 cm, though the inferior aspect of the right lobe is substernal and incompletely visualized.LEFT LOBE MEASUREMENTS: 6.1 x 2.7 x 0.7 cm.ISTHMUS MEASUREMENTS: 4 mm in AP dimension.RIGHT LOBE: A large heterogeneous minimally hypoechoic nodule is noted extending from the inferior pole. The inferior margin is not visualized due to substernal extension, though this approximately measures 3.0 x 2.3 x 2.8 cm. The echotexture of this nodule along with areas of comet tail artifact suggest this to be an intrathyroidal nodule. A large cystic nodule inferior and posterior to this nodule is also incompletely visualized due to substernal location, though measures approximately 2.9 x 2.2 x 1.8 cm. This does not appear to arise from the thyroid gland. An additional homogeneous 9 mm minimally hypoechoic nodule is noted in the midpole.LEFT LOBE: Two large heterogeneous minimally hypoechoic nodules in the inferior pole measure 3.3 x 2.8 x 1.4 cm and 3.8 x 3.0 x 3.2 cm.ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: Not visualized.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Multiple large thyroid nodules in the inferior thyroid poles bilaterally, extending into the superior mediastinum on the right.2. Cystic nodule adjacent to the right thyroid lobe inferior pole is incompletely visualized though appears to be extrathyroidal extending into the superior mediastinum.
