title: Problems in air cisternography.
abstract: False-positive computed tomography with air cisternography is suspected with either air in the lateral internal auditory canal or a flat filling defect. False-negative air cisternography should be suspected if the internal auditory canal has a mottled appearance or if audiometric or auditory brain-stem response deficit progresses.
