ANOMALOUS COMMISSURE OF THE THIRD VENTRICLE (ABERRANT DORSAL SUPRAOPTIC DECUSSATION): A REPORT OF EIGHT CASES

Abstract

Abstract An examination was made of the third ventricle in 371 human brains removed at autopsy at the Cincinnati General Hospital. In 8 instances an anomalous commissure connecting the lateral walls of the third ventricle was observed, making an incidence of approximately 2.15 per cent. Grossly, these brains, fixed in a solution of formaldehyde, present a yellow thread about 1 mm. in diameter traversing the third ventricle and joining its walls. In sections from the frontal lobe the structure is found in the plane which passes between the anterior commissure and the posterior portion of the optic chiasm. In a ventrodorsal aspect of the third ventricle in this plane it lies at slightly varying distances from a middle level. In one instance the commissure was composed of two fine filaments (fig. 1). For microscopic study, 6 of the specimens were sectioned serially in the frontal plane. Of these, 3 were prepared References 1.
