The causes of osteolytic lesions found in radiological examinations are not quite certain. Therefore, to determine the appropriate treatment method, various approaches and analyzes are required to find the real cause. Hyperparathyroidism is one of the diseases which forms osteolytic bone lesions so-called brown tumor. A 55-year-old woman who had painful osteolytic bone lesions in both hip joint areas was diagnosed as parathyroid carcinoma after serial work-up. She underwent parathyroidectomy and follow-up imaging showed a decrease in brown tumor size and bone consolidation in the subchondral bone destruction area. Proper evaluation of osteolytic bone lesions helps to avoid unnecessary operative treatments and the first choice for the treatment of osteolytic bone lesions caused by parathyroid carcinoma is parathyroidectomy.

Brown Tumor of the Patella Caused by Primary Hyperparathyroidism: A Case Report

et al. 2015

It has been reported that the common sites of brown tumors are the jaw, pelvis, ribs, femurs and clavicles. We report our experience in a case of brown tumor of the patella caused by primary hyperparathyroidism. An initial radiograph and CT showed an osteolytic lesion and MR images showed a mixed solid and multiloculated cystic tumor in the right patella. One month after the parathyroidectomy, rapid bone formation was observed on both radiographs and CT images.

“…Brown tumor, also called osteitis fibrosa cystica, is an advanced form of renal osteodystrophy caused by excessive osteoclastic activity from primary or secondary hyperparathyroidism (HPT). It classically manifests as lytic bone lesions with well‐defined borders, although healing lesions will demonstrate various levels of sclerosis . Brown tumor is reported to occur in 1.5–13% of patients with secondary causes of HPT .…”
