Arachnoid cysts represent less than 1% of brain tumors. There are few reports of subarachnoid cysts of the temporal lobe with subsequent remodeling of the orbit, however there are no reports regarding the reconstructive management of the orbital cavity in this pathology. We report the case of a man of 44 years with diagnostic of neurofibromatosis type 1 who presented progressive increase in volume of the left eye of 40 years of evolution, with intermittent retro-ocular pain. A temporal lobe arachnoid cyst was diagnosed invading the orbital cavity and dysplasia of the greater wing of the sphenoid. Drainage and cystocisternostomy of arachnoid cyst was performed, with orbital wall reconstruction with titanium mesh and covered with a flap of pericranium as well as the lifting and repositioning of the eyeball by canthopexies and orbital osteotomy to decrease the volume of the cavity.
