A Unique Case of Osteitis Fibrosa Cystica with Postoperative Hungry Bone Syndrome and Hypocalcemic Cardiac Failure

Abstract

ABSTRACT Osteitis fibrosa cystica, a manifestation of severe hyperparathyroidism presenting with crippling bone deformities is a rare presentation these days. We report a case of 40-year-old male patient who presented with generalized aches and pains and bony deformities. Radiographs showed diffuse osteopenia, brown tumors and pathological fractures of phalanges but common manifestations associated with hyperparathyroidism like pancreatic calcifications and nephrolithiasis were absent. Serum calcium and parathyroid hormone levels were elevated while ultrasound imaging of neck showed the presence of a left lower parathyroid adenoma and was confirmed by Tc99- sestamibi scan. Large parathyroid lesion along with high calcium levels and severely elevated PTH puts this patient in high-risk category for postoperative hungry bone syndrome leading to severe hypocalcemia postoperatively. Hypocalcemia usually results in neuromuscular irritability manifesting as paresthesia, Chvostek and Trousseau sign, carpopedal spasm and even convulsions in severe cases. However, our patient had none of the common manifestations, but developed hypocalcemic cardiac failure postoperatively. Case history and management of case is presented.
