A 62-year-old woman presents to her GP with a 6-month history of increasing fatigue, generalised bone aches, and constipation. She has no significant past medical history and takes no regular medications. Physical examination is unremarkable. Initial laboratory investigations reveal a corrected serum calcium level of 3.1 mmol/L (reference range: 2.1-2.6 mmol/L) and an elevated parathyroid hormone (PTH) level of 180 pg/mL (reference range: 10-65 pg/mL). A 24-hour urine calcium excretion is 12 mmol/day (reference range: 2.5-7.5 mmol/day). She is referred for further imaging, the results of which are shown. Based on the available information, what is the MOST appropriate next step in the management of this patient?
