Herniation of the optic chiasm and third ventricle into a partial empty sella


Herniations into the sella have been described associated either with primary or secondary empty sella. Such as in this case, visual disturbances have been well documented associated with secondary empty sella (medical/surgical therapy of a sellar tumor like marcoadenoma). 

Unfortunately, previous imaging were not available to make a clear correlation with the tumor (documented macroadenoma).
