BROWN tumor arising in the retroorbital region has not, to our knowledge, been previously reported. We report the case of a woman with chronic renal failure and a rapidly progressive proptosis with loss of visual acuity secondary to orbital brown tumor.
Report of a Case
A 24-year-old woman receiving long-term hemodialysis, with a four-year history of renal failure secondary to glomerulonephritis, was admitted to Montefiore Hospital on July 30, 1976, complaining of rapidly progressive proptosis of the right eye (OD), right-sided headaches, decrease in visual acuity, and right facial numbness. She had a 12-mm proptosis of the right eye, with severe reduction in extraocular motion in all directions. Visual acuity was 20/70 OD, and 20/25 in the left eye. A Marcus-Gunn pupil was present in the right eye. Funduscopic examination showed striking choroidal folds in the posterior pole of the right eye. Hypesthesia was present in the right infraorbital nerve
