title: Maxillary brown tumor and uremic leontiasis ossea in a patient with chronic renal insufficiency.
abstract: Findings of renal osteodystrophy in cranial bones are not uncommon and include osteomalacia, osteosclerosis, erosion of the cortical bone, brown tumors and resorption of the lamina dura. However, massive thickening of the cranial vault and facial bones, called uremic leontiasis ossea, have been reported very rare. In the present article, we describe the case of an uncooperative female patient with a brown tumor, involving the left maxillary sinus and massive thickening of the cranial vault and facial bones, secondary to severe secondary hyperparathyroidism during 8 years of regular hemodialysis treatment.
