  • Abstract
  • Look Inside

A 51-year-old female had noted proptosis of her left eye 11 years before. She had lost vision in the af-fected eye a few years later. She visited us for further progression of proptosis. Her visual acuity was 1.0 right and no light perception left. The proptosis was 12mm right and 31mm left by Hertel. Her left eye showed optic atrophy. There were no signs of cranial nerve involvement. Computerized tomography (CT) showed a well-defined tumor fill-ing the left orbit. The orbital walls showed hypertrophy and no destruction. The tumor extended to the cavernous si-nus, meningeal sinus and the area around the brain stem. Biopsy of the orbit led to the diagnosis of meningothelioma-tous meningioma. The orbital tumor was surgically removed by lateral approach of Krönlein. The eyeball was kept in-tact. After surgery, proptosis improved dramatically together with lagophthalmos. It appears that the megingioma origi-nated intraorbitally without involving the optic nerve to later extend posteriorly through the superior orbital fissure or the optic canal.
