Benign cervical thymoma masquerading as a malignant thyroid nodule.
A thymoma in the neck region is a rare diagnosis involving a solitary neck nodule that moves with deglutition and is contiguous with the thyroid gland. The authors report an unusual case of a thymoma that accumulated both Tc-99m pertechnetate and Tc-99m MIBI. This is probably the first reported case of a benign neck thymoma concentrating these two radiopharmaceuticals. Thymoma should be added to the gamut of false-positive findings in the neck for thyroidal (with Tc-99m pertechnetate) and malignant (with Tc-99m MIBI) tissue.
