Sellar-parasellar brown tumor: case report and review of literature.
Brown tumors are the end stage of primary or secondary hyperparathyroidism. Such lesions are rare because hyperparathyroidism is now usually diagnosed and treated before they develop. Skeletal bone is most frequently involved, whereas sellar-parasellar involvement is extremely rare. We report a patient with a brown tumor involving the sellar-parasellar region associated with primary hyperparathyroidism. The patient's clinical history and biochemical and radiological tests were used for the diagnosis. Excision of the sellar-parasellar mass enabled histopathological confirmation and surgical decompression of neural structures. After the transsphenoidal surgery, excision of a parathyroid adenoma normalized the patient's metabolic status. Brown tumors are rarely associated with complications but occasionally may compress neural structures such as the optic nerve as they enlarge.
