Primary hyperparathyroidism revealed by a pathological fracture is very uncommon. We report a 47-year-old female patient with multiple pathological bone fractures. The diagnosis of primary hyperparathyroidism was made based on these bone changes and the elevated parathyroid hormone level. The histopathological findings confirmed the diagnosis of primary hyperparathyroidism with brown tumor. Patient was discharged in a stable condition with both fractures united six months after the surgery.
