[A case of nasofrontal encephalomeningocele with review of literatures and experiences of 14 cases of cephaloceles (author's transl)].

A case of 2-month-old boy with nasofrontal encephalomeningocele was presented, which was excellently treated via intradural approach, followed by removal of herniated sac. Under the knowledge of reviewed literatures and our experiences of 14 cases of cephaloceles, its symptomatology, diagnosis and policy of treatments were discussed. As rare case was an intracranial meningoencephalocele in our series described, which showed a supracollicular cyst with brain tissue wall, communicating with aqueduct. Other emphases were placed on the differential diagnosis from holoprosencephaly with extracranial dorsal sac, the usefulness of CT-scan as a diagnostic tool and our method of closing dural defects in anterior cranial fossa by reflecting dura on frontal lobe.
