  • Title: Scintigraphic diagnosis of thyroid cancer. Correlation of thyroid scintigraphy and histopathology.
    Author: Oommen R, Walter NM, Tulasi NR.
    Journal: Acta Radiol; 1994 May; 35(3):222-5. PubMed ID: 8192956.
    Abstract:
    Scintigraphy is part of the routine examination of thyroid disease, yet there are few published reports on its utility and pitfalls. Out of 2025 consecutive thyroid examinations after excluding 230 cases of proven thyroid malignancies, 403 patients who underwent surgery were studied for histopathologic correlation. There were 232 with cold nodules, 143 with multinodular goiters (MNG) and 28 with uniformly increased uptake suggestive of toxic goiter. Malignancy was reported in 72 of the 232 cold nodules (31%). In solitary nodules, the examination was useful in selecting cases for surgery and, in cold lesions, for planning of surgery. In the majority of patients with MNG or thyrotoxicosis who were operated on, scintigraphy provided no additional information. MNG requires scintigraphy only in selected cases where there is strong suspicion of malignancy. Contrary to reports in the literature, papillary carcinoma was found to be associated with MNG in our patients.
