The meningioma of the sphenoidal plane.

The present paper reports on meningioma of the sphenoidal plane. Four women and two men were investigated. All cases examined presented with impairment of visual acuity, optic atrophy, and visual field defects. The interval between onset of the disease and a noticeable space-occupying growth was 11.5 years. Frequent false diagnoses and the importance of clinical-roentgenological follow-ups at regular intervals are especially emphasized.
