title: Evaluation of an aviator with chronic disequilibrium, oscillopsia, and central sleep apnea.
abstract: A case is presented of an aviator with chronic disequilibrium, oscillopsia, and central sleep apnea. History, physical examination, and special studies are presented establishing a diagnosis of epidermoid tumor at the foramen magnum. Differential diagnosis and relation of findings to the lesion are presented. The aeromedical significance of this case is to reinforce the importance of persistence and the team concept in establishing diagnoses when aviators present with confusing or unexplained symptoms.
