case_images: In February 2023 neck ultrasonography showed nonhomogenic thyroid with coarsened parenchyma and one large, approximately 35 mm long, hypoechoic nodule with calcification near the left thyroid lobe (Figure 1).
case_images: Scintigraphy, early phase. Retention of the radiotracer near the left thyroid gland. Two segments merged into one mass can be identified.

case_images: During physical examination before surgery neck size and patient's voice were normal (Figure 4).
case_images: Excised double parathyroid adenoma, which has got two fragments. In total it is 40 mm long (a) and 15 mm wide (b).

case_images: During surgery parathyroid adenoma was recognized and excised (Figure 5).
case_images: Histopathological view of the excised adenoma. Black arrow marks follicles filled with eosinophilic colloid material and vacuolization on its periphery, that shows active resorption of tumor produced product. Green arrow points to large capillary with intralumenal erythrocytes.
