Basal encephalocele associated with suprasellar epidermoid cyst.

A 27-year-old woman suffered from multiple congenital defects, including transsphenoidal encephalocele. Recent progressive visual loss was at first attributed to this encephalocele, but was later proved to be caused by a suprasellar epidermoid cyst. Its removal was followed by improvement of vision. To the best of our knowledge, the association of basal encephalocele and epidermoid cyst has not been previously described.
