A combined morphological study using transmission and scanning electron microscopy was carried out on the central zone of the rostral wall of the 111 ventricle from a sample taken during the operation of a patient with a retrochiasmatic craniopharyngioma.
Under the scanning electron rnicroscope, the apical cell wall of the ependymocytes generally appeared folded and lack in ciliae, but with numerous microvilli developed to different extents. The flat surface cells were scarce and were polygonal in shape and limited by 3-7 prominent edges. Ultrastructural analysis revealed the existence of severa1 types of ependymocytes and subependymal epithelial cells arranged in different layers; in both layers the presence of abundant neurofilaments and intercellular junctions was striking.
