History An 82-year-old right-handed man with myasthenia gravis presented in May 2014 with double vision andright facial numbness and weakness. He was first seen in 1998 with horizontal diplopia. He had anabduction deficit of the right eye, and right nasolabial fold flattening. He was diagnosed withmyasthenia based on a positive acetylcholine receptor blocking antibody. His chest CT scan wasnegative for thymoma. His diplopia and facial weakness resolved with azathioprine and prednisone. Hehad central retinal vein occlusion (CRVO) in the right in 2002, with resultant optic neuropathy andcentral vision loss. He had removal of innumerable squamous and basal cell carcinomas, coronary arterydisease, prostate cancer with prostatectomy and laryngoplasty. In 2009, he first noticed right brownumbness. He had surgery for ectropion OD in April 2013. In May 2013, he developed dysesthesia ofhis right brow. A basal cell carcinoma was removed without benefit. In July 2013, his myasthenia wasstable, but his azathioprine was decreased due to reduced platelets and hematocrit. In September 2013,he developed stabbing pain of his right cheek, with right cheek sensory loss and right facial weakness. AMRI in November 2013 showed a small enhancing intraconal mass, not in an MRI from 2006. In April2014, he had Mohs excision of a poorly differentiated scalp squamous cell carcinoma. In May 2014, hisafferent examination was stable. Eye movements showed new -2 limitation of abduction OD. He hadsensory loss of his right cheek, and right facial weakness. Increasing his prednisone dose did notimprove his eye movements. Repeat brain MRI in May 2014 showed increase in size of the orbital mass.The third, fourth, fifth, sixth, and seventh cranial nerves appeared normal. A diagnostic procedure wasperformed.
