case_images: Her X-ray examination on chest, thoracic and lumbar vertebrae, left femur and skull were all normal (Fig. 1).
case_images: Color ultrasonography examination. (A) Thyroid color ultrasonography showed multiple nodules with high echo (a 21 mm x 11 mm high echo thyroid nodule was represented by a red arrow). (B) Right kidney stone (a single hyperechoic nodule of 11 mm x 8 mm with acoustic shadow, represented by a red arrow), right kidney cysts (represented by yellow arrow); (C) hysteromyoma (red arrow).

case_images: Color ultrasonography showed thyroid multiple nodules with high echo patterns (right lobe: 20 mm x 13 mm; left lobe: 10 mm x 8 mm; isthmus: 7 mm x 7 mm) and no malignant lesions were found, hysteromyoma, right kidney stone (a single hyperechoic nodule of 11 mm x 8 mm with acoustic shadow), double kidney cysts (left kidney cysts was no shown), and normal breast and heart structures (Fig. 2).
case_images: Thyroid ultrasound image: Sulfur hexafluoride contrast-enhanced ultrasound revealed nodular goitre with no malignant changes. Two thyroid nodules (above: 21 mm x 11 mm; below: 14 mm x 21 mm) were represented by red arrows.

case_images: Serum calcium and phosphate levels after treatment of hyperthyroidism and hypercalcemic crisis. Area confined by 2 short dash lines represented the normal range of serum calcium (between 2.08 and 2.80 mmol/L) and area confined by 2 long dash lines represented the normal range of serum phosphate (between 0.90 and 1.34 mmol/L). Ca = calcium, P = phosphate.

case_images: Her serum calcium level quickly returned to normal after 24 hours of treatment, although it fluctuated at days 4 and 5 (Fig. 4). Eight months later, her calcium (2.47 mmol/L) and phosphorus (1.10 mmol/L), as well as her thyroid function remained normal (Fig. 4).
