History A 58-year-old man presented for the development of new stabbing headaches and blurry vision in the right eye. Over; several months, his symptoms progressed to 'smudging' of his temporal field in the right eye, difficulty separating similar; colors, and binocular horizontal diplopia worse at near. Medical history was notable for a melanoma resected from the; right arm with negative margins 8 years prior to presentation with normal screening examinations thereafter. His initial; ophthalmic exam showed visual acuities of 20/125 eccentrically OD and 20/40 OS, a trace right rAPD, ⅛ color plates OD and; ⅜ color plates OS. Fundus exam revealed macular edema OD. Automated visual fields showed a complete right temporal; hemifield defect OD with nonspecific defects OS. OCT showed subretinal fluid and choroidal neovascularization OD. An MRI; showed a large mass extending from the sella and superiorly displacing the chiasm, inferior frontal lobes, and cavernous; sinus with osseous erosion of the adjacent bony structures and multifocal hemorrhage within the lesion. He received urgent; transsphenoidal pituitary resection to relieve the compression of his right optic nerve, though the left portion of the lesion; was left untouched due to encasement of the carotid. Pathology showed a gonadotroph adenoma with a markedly elevated; proliferation index of 22.8% and scattered areas of necrosis. He received intravitreal bevacizumab in consultation with the; retina service for his choroidal neovascular membrane. Repeat neuro-ophthalmic examination one month after surgery; showed visual acuities of 20/125 OD and 20/20 OS with a right rAPD, 8/8 color plates OU, and dramatically improved visual; fields. Follow up MRI two months after surgery showed a significant interval increase in the size of his pituitary lesion with; extension into the resection cavity and new multifocal contrast enhancing brain lesions. Additional examination and; imaging was performed.
