Encephaloceles are congenital defects in the skull through which menings and brain tissues herniated. Basal encephaloceles are found in 1 in 40,000 live births. Transsphenoidal basal encephaloceles are very rare, accounting for only 5% of all basal encephaloceles. Currently, most encephaloceles are diagnosed antenatally and present at birth. Postnatally, infants may present with CSF rhinorrhea, recurrent meningitis, headache, hypothalamic- pituitary dysfunction. Some, particularly trasnssphenoidal encephaloceles are often clinically occult and diagnosis of the disease may be postponed up to adulthood. Surgical indications and approaches for transsphenoidal encephaloceles have been remained controversial. We report a case of CSF rhinorrhea and recurrent meningitis caused by transsphenoidal encephalocele.
