A patient with femoral osteitis fibrosa cystica mimicking bone neoplasm: a case report.

Background: Osteitis fibrosa cystica is a rare, benign and osteolytic lesion attributed to hyperparathyroidism. The high level of parathyroid hormone cause rapid bone loss.Case Presentation: The patient is a 50-year-old male complaining of severe and persistent pain in the right knee joint. Imaging studies were suspicious for a benign tumor in the right distal femur. Biopsy under CT guidance showed numerous osteoclast aggregation and hemosiderin deposition around the bone trabeculae. Blood tests disclosed significantly elevated parathyroid hormone, serum calcium, serum alkaline phosphatase. Parathyroid ultrasonography and CT scan showed a solid mass in front of the trachea at the thoracic entrance plane. After resection of the mass, the clinical symptoms were relieved and the radiological results were significantly improved, which further confirmed the diagnosis.Conclusions: Metabolic diseases-associated bone lesions require a comprehensive diagnosis of multiple inspection items. An interprofessional team approach to the diagnosis and treatment of osteitis fibrosa cystica will provide the best outcome. [ABSTRACT FROM AUTHOR]
