Abstract
INTRODUCTION: Primary hyperparathyroidism is a commonly occurring endocrine disorder that is characterized by elevated calcium levels, decreased phosphate levels, and high levels of parathyroid hormone (PTH). The condition can lead to significant bone resorption and pathological fractures. CASE REPORT: We report a case of a 44-year-old female who presented with bilateral thigh pain after a trivial fall at home. Radiological investigations revealed a subtrochanteric fracture of the bilateral femur that was deemed pathological. Biochemical testing indicated severe hypercalcemia and hypophosphatemia with elevated levels of serum PTH and an increased alkaline phosphatase level. Ultrasound and computed tomography scans confirmed a parathyroid adenoma, which was treated through excision and histopathological examination. The patient underwent orthopedic intervention for bilateral subtrochanteric femur fracture, and follow-up investigations showed normal biochemical markers and fracture union within 6 months. CONCLUSION: Primary hyperparathyroidism should be kept in mind when dealing with bone lesions connected to hypercalcemia, even in asymptomatic individuals and individuals presenting with a trivial mode of trauma. The diagnosis of parathyroid adenoma requires a combination of radiological and biochemical investigations, and a multidisciplinary approach is recommended for the best possible outcome.
