The Probst bundle associated with anomalies of the precommissural separated fornix in an acallosal brain

ABSTRACT

Dissection of the brain disclosed a unique form of the Probst bundle and a rare variation of the precommissural fornix. The latter showed an unusual size, branches and path on the medial surface of hemisphere. Its posterior branch continued to curve parallel with the posterior commissural fornix to follow an abnormal path and end in the hypothalamus. The Probst bundle was intermingled with the separated fornix in an anteroposterior direction as well as in the anterior and posterior parts in an atypical way. Focusing on such morphological abnormalities may help to gain a better understanding of the pathophysiology of brain disorders (AU)
