title: Human botulism (type F)--a rare type.
abstract: An unusual presentation of type F botulism (one of the world's three reported outbreaks) is described. The diagnosis was complicated by the presence of pre-existing Adie's myotonic pupil. There was also a history of self-inflicted small-caliber gunshot wound to the right brain 10 years before the onset of the botulism. Post-traumatic seizure disorder, also present in this patient, was under good control. No offending food was ever discerned, despite exhaustive study.
