Visualization of a parathyroid adenoma with Tc-99m MIBI in a case with iodine saturation and impaired thallium uptake.
A case of a parathyroid adenoma is presented in which the conventional Tl-201 minus Tc-99m subtraction technique failed to localize the adenoma because of prior iodide administration and a low Tl-201 uptake. Ultrasonography and CT could not provide useful data either. However, a Tc-99m methoxylisobutylisonitrile (MIBI) scintigram clearly delineated the adenoma and the thyroid tissue.
