title: Thirteen-And-A-Half Syndrome.
abstract: We describe a 50-year-old man who developed eight-and-a-half syndrome associated with an ipsilateral trigeminal nerve palsy because of a post-transplant lymphoproliferative disorder. This case widens the spectrum of eight-and-a-half syndrome to include a thirteen-and-a-half syndrome.
