Scintigraphy may show diffusely decreased radionuclide uptake or isolated areas of impaired uptake within the gland. The RAIU by the thyroid gland is decreased, usually to < 5%. Ultrasound during the acute thyrotoxic phase demonstrates diffuse hypoechogenicity similar to that of Graves’ disease, but color-flow Doppler imaging shows no increased vascularity, thus differentiating it from Graves’ disease. During recovery, RAIU may rise to elevated levels before returning to normal as the process resolves.
Discussion: The scintigraphic finding of diffuse toxic goiter and an elevated RAIU in a young woman with hyperthyroidism is diagnostic of Graves’ disease. The pyramidal lobe, a remnant of the distal thyroglossal duct, is identified in less than 10% of euthyroid patients but is visualized in as many as 43% of patients with Graves’ disease (Fig. 4 A). The hyperthyroidism of Graves’ disease is often accompanied by exophthalmos and sometimes pretibial myxedema. 1). Clinical history and physical examination combined with serum hormone and antithyroid autoantibody levels, thyroid scintigraphy, and RAIU measurement usually allow identification and differentiation of the various etiologies.
There is no scintigraphic evidence of recurrent MIBG-avid medullary thyroid carcinoma. Pheochromocytomas are catecholaminesecreting neoplasms arising from chromaffin cells. Approximately 10% are malignant, 10% are bilateral, 10% occur in children, and 10% to 20% are extra-adrenal in origin (paragangliomas), usually in the abdomen or pelvis but occasionally in the neck or mediastinum. Bilaterality, extra-adrenal sites and malignancy are more common in children. 28). The sensitivity of 131 I-MIBG for the detection of primary pheochromocytoma, paraganglioma, and metastases is approximately 86%, but it is higher (95%) for 123 I-MIBG.
