Multiform thyroid cancer-scintigraphic and echographic features.

In a patient with multinodular goiter, one of the three solid nodules harboring follicular carcinoma appeared functional in the 99mTc-pertechnetate image, yet "cystic" in both A-and B-mode echogram studies. The other two nodules corresponded in their image and echogram features and contained papillary and anaplastic carcinomas, and Hashimoto's thyroiditis. Clinical acumen proved to be the best guide in the management of this patient.
