Brown Tumor of the Orbital Roof as an Initial and Isolated Manifestation of Secondary Hyperparathyroidism

Abstract

Brown tumors appear in advanced stages of hyperparathiroidism. Only 17 cases have been documented in the orbit. We report a case of a young woman with a brown tumor in the orbital roof. Secondary hyperparathyroidism due to chronic renal disease was detected during the preoperative study. The pathogenesis, diagnosis and management of the brown tumor are discussed.
