Maxillofacial Enlargement in Secondary Hyperparathyroidism Successfully Treated by Limited Parathyroidectomy and Paricalcitol = Maxillofacial Enlargement in Secondary Hyperparathyroidism Successfully Treated by Limited Parathyroidectomy and Paricalcitol

다국어 초록 (Multilingual Abstract)

Maxillary enlargement is a rare complication of secondary hyperparathyroidism (SHPT). A 35-year-old Korean man undergoing chronic hemodialysis presented with a painless enlargement involving the maxilla and mandible. Plain radiography and CT scan showed bony expansion at the maxilla and mandible with multiple radiolucency. Serum intact parathyroid hormone (iPTH) was >600 pg/mL. Tc- 99m sestamibi (MIBI) parathyroid scan and neck sonogram were compatible with SHPT. He underwent limited parathyroidectomy and commenced a course of paricalcitol. Fifteen months after surgery, maxillary enlargement and bony resorptions involving both hands markedly improved. Thirty-six months after the surgery, the serum iPTH level was 109.3 pg/mL. This is the first report in Korea documenting a patient with maxillary enlargement in SHPT who was successfully treated with limited parathyroidectomy and paricalcitol.
