[Use of SPECT with (99m)Tc-Sestamibi in a patient affected by laryngeal carcinoma and parathyroid adenoma].
We report the case of a patient with a laryngeal carcinoma in whom asymptomatic hyperparathyroidism was also detected during the preoperative work-up. A planar (201)Thallium/(99m)Tc-pertecnetate subtraction scintigraphy was performed in order to locate the suspected parathyroid adenoma. The study showed a single area of increased (201)Thallium uptake just above the thyroid isthmus, likely due to the laryngeal tumor. The scintigraphic study was repeated using (99m)Tc-Sestamibi and (99m)Tc-pertechnetate and employing the SPECT technique. Both SPECT studies made it possible to identify correctly the parathyroid adenoma, located inferiorly and in a posterior position to the lower third of the right thyroid lobe. The laryngeal tumor and parathyroid adenoma could be excised in a single surgery session. This case is of interest due to the rarity of the coexistence of two neck tumors and the clear advantage shown by the SPECT technique with (99m)Tc-Sestamibi over the planar technique with 201Thallium.
