28 Mar A case of intrathyroid parathyroid tumor that was difficult to diagnose by ultrasonography
With advances in diagnostic imaging such as ultrasonography (US), computed tomography (CT), and 99mTc-MIBI-sestamibi (MIBI) scintigraphy, localized diagnosis of hyperparathyroidism (pHPT) has become possible with considerable accuracy.
However, even with the use of these imaging techniques, since intrathyroid parathyroid tumors exist as a mass within the thyroid, it is often difficult to distinguish from thyroid masses.
Although there have been various reports on US images of intraparathyroid tumors, we experienced a case with US images that were distinct from previous reports.
Herein we present a case of an intrathyroid parathyroid adenoma (IPA) that was difficult to diagnose, with a main focus on US images.
