His physical examination revealed a blood pressure of 170/110 mm Hg, facial asymmetry with proptosis of the left eye, Lisch nodules in the right eye, normal cardiopulmonary function, and a soft abdomen without hepatosplenomegaly or masses. No bruits were present. His skin showed multiple café au lait spots, axillary freckling, and a neurofibroma on his left ankle.
