SPHENOID SINUS BROWN TUMOR IN PRIMARY HYPERPARATHYROIDISM- A CASE REPORT

Brown tumors are expansile osteolytic lesions of bone, occurring in hyperparathyroidism. Skeletal involvement in primary hyperparathyroidism secondary to parathyroid adenoma is very uncommon and brown tumor has become extremely a rare clinical entity. Brown tumors occur most commonly in ribs, mandible, clavicle, and pelvis, and are uncommon in the facial bones. We report a rare case of primary hyperparathyroidism presenting with brown tumor in the sphenoid sinus and the relevant literature is reviewed.
