A 68-year-old man presents for elective parathy-roidectomy.
The patient was diagnosed with parathyroid adenoma after a blood test in
preparation for elective cataract surgery revealed hypercalcemia. Further blood
tests demonstrated an elevated parathyroid hormone (PTH) level, and
technetium-sestamibi scans showed hyperactivity in the right lower gland. The
patient also has a history of well controlled hypertension.
