title: An unusual scintigraphic pattern of benign thyroid nodules. The "fish eye" sign.
abstract: The authors describe three cases of an unusual scintigraphic pattern of benign thyroid nodule with ultrasonographic appearance. A nodule of normal, increased and decreased Tc-99m pertechnetate concentration surrounded by a rim of cold area was noticed in three patients in whom fine-needle aspiration biopsies revealed benign follicular cells.
