Osteolytic lesion of primary hyperparathyroidism masquerading as multiple myeloma: A diagnostic conundrum of multiple pathological fractures

Abstract

Osteitis fibrosa cystica or brown tumor is a rare skeletal manifestation of hyperparathyroidism. Awareness of this condition is imperative to making a correct diagnosis. We present a case with multiple pathological fractures who had undergone extensive workup for malignancy before reaching the definitive diagnosis of primary hyperparathyroidism.
