The prognosis of occipital encephalocele.

147 cases of occipital cranium bifidum have been followed: 32 had meningoceles and 115 encephaloceles. Females predominated (69%). 90% of the meningocele and 43% of the encephalocele patients survived. Of the former 48% are normal and 16% are both physically and mentally handicapped. Of the latter only 4% are normal and 26% are physically and mentally handicapped. Cerebral tissue in the sac and associated microcephaly are bad prognostic features.
