Interesting Images

Parathyroid carcinoma is uncommon, and its coexistence with parathyroid adenoma is extremely rare. A 28-year-old woman with hyperparathyroidism underwent dual-phase 99mTc-sestamibi SPECT/CT scan for presurgical evaluation. The images showed intense activity inside the left side thyroid and mild activity inside the right side of the thyroid. The histopathologic findings showed intrathyroidal parathyroid carcinoma on the left side and intrathyroid parathyroid adenoma on the right side.
