Localization and Amount of Thyroid Remnant in Totally Thyroidectomized

Objective:To determine the frequency, localization and amount of thyroid remnant in extracapsular thyroidectomized patients.Methods:We postoperatively evaluated the thyroid bed of 38 totally thyroidectomized patients using thyroid scintigraphy, a thyroid uptake study and bilateral neck ultrasonography (US) to determine the extent of residual thyroid tissues.Results:In scintigraphic assessment, thyroid remnant was not seen in the thyroid bed in 13 cases, minimal thyroid remnant was detected in 15 cases, and visible uptake was seen in 10 cases. Ultrasonographic findings revealed the presence of remnant in 12 cases. However, US did not detect all remnant tissues diagnosed by TS.Conclusion:This study demonstrates that minimal thyroid remnant is left in the majority of cases, even after extracapsular total thyroidectomy, especially in the upper and middle zones

A Case with Non-Small Cell Cancer in the Left Lung Diagnosed Following Observation of Bilateral Diffuse Lung Uptake of Tc-99m-MDP on Bone Scintigraphy

Extraskeletal accumulation of Technetium-99m methylene diphosphonate (Tc-99m-MDP) can be seen in bone scintigraphy both in benign and malignant lesions. In malignant lesions, this phenomenon is usually associated with microscopic calcifications due to the abnormal calcium metabolism, and occurs most frequently in the lungs. In this case report, we present a patient with a non-small lung cancer diagnosed following observation of incidental bilateral lung MDP accumulation in bone scintigraphy. Therefore, the tracer distribution in the soft tissues needs to be carefully examined on bone scans and any unexpected visible soft tissue activity should be stated on the scintigraphy report
