Incidence of pyramidal lobe on thyroid scintigraphies

Abstract

Introduction: The pyramidal lobe, an embryological remnant of the thyroglossal duct, extends up anatomically from the lobes or isthmus of the tyroid gland. It is important to know the localization of pyramidal lobe in the cases who will undergo to total thyroidectomy operation. Materials and Methods: The Tc-99m pertecnetate thyroid scintigraphies were performed on 805 patients (616 women, 189 men) aged between 19 to 78 years, in order to determine the incidence of pyramidal lobe on thyroid scans. Result and Discussion: The pyramidal lobe was visualized in 20.8% of cases. The frequency of appearance was slightly higher in males than females. Pyramidal lobe was usually located on the left lobe in both sex. Interestingly in two cases (one woman and one man) it was found that two pyramidal lobes extending from the each lobes of thyroid. Investigating thyroid function studies of the patients with a pyramidal lobe on their scans we determined the high incidence (79.1%) of euthyroidism. Only 12.5% and 8.3% of the patients showed hyperthyroidism and hypothyroidism respectively. All of the patients with hyperthyroidism had the findings of diffuse toxic goitre. Pyramidal lobe should be taken into consideration in patients referred for total thyroidectomy operation. Before thyroid operation, Tc-99m pertechnetate scan will be helpful in the localization of pyramidal lobe, because it is a functional imaging modality.
