Figure 1 Parathyroid adenoma on the dorsal of the superior pole of the left lobe of the thyroid gland. A: Ultrasonography shows a hypoechoic nodule on the back of the left lobe of the thyroid gland; B: The nodule was positive on technetium-99 m sestamibi single-photon emission computed tomography/computed tomography; C-F: Magnetic resonance imaging with contrast shows the nodule and is distinct in the coronal (C), axial (D and E), and sagittal positions (F), respectively; G: The correlation between parathyroid adenoma (PA) and the left thyroid lobe is shown, and the PA capsule should be carefully protected during surgery; H: The size of the PA was measured; I: The pathological result confirmed that the nodule was a PA.
