Abstract

A 77-year-old man with a case of hyperthyroidism with high parathyroid hormone (41 pmol/L), low vitamin D, and normal thyroid-stimulating hormone. The SPECT/CT fused images confirmed the evidence of retrotracheal hyperdense mass approximately 1.0 cm of diameter below the lower pole of the right thyroid lobe with increased uptake, highly suggestive of typical parathyroid adenoma. The most significant point is that there was an incidental finding: high focal uptake in the sellar/suprasellar region corresponding to heterogenous soft tissue lesion suspicious for pituitary adenoma. According to the previous scans, nuclear medicine, CT scan, and the MRI scan indicated pituitary adenoma.
