A 50-YEAR-OLD WOMAN presented with a 4-month history of multiple midline, infrahyoid, cystic masses that moved on swallowing. The thyroid radioisotope scan (technetium 99m) (Figure 1) showed that the midline mass was functioning thyroid tissue separate from, and above, the main mass of the thyroid gland, which was irregular in shape and uptake, with most of the functioning tissue in the midline. The results of fine-needle aspiration cytology of the lump were nondiagnostic. Subsequent cytologic examination of a fine-needle aspirate, however, revealed psammoma bodies.
