In this study of @entity3976 , the authors have considered the pedunculated or sessile type of cephalocele and also small nonpedunculated scalp defects developing in the vertex midline. Parietal cephaloceles were found in 15 @entity1 (10 @entity1 and five @entity1 ), and accounted for 37.5% of all cephaloceles. They consisted of four @entity3976 , six meningoceles, and five @entity3976 . The clinical and morphological characteristics of parietal cephaloceles were investigated and compared with those arising at other locations. Parietal cephaloceles carried a much less favorable prognosis than those in the occipital region, regardless of the type of cephalocele; they were associated with @entity1779 more frequently and were more severe than occipital cephaloceles. Grave @entity154 were found in 87% of @entity1 with parietal cephalocele, and only two @entity1 (neither of whom had any other @entity600 ) attained normal development. @entity75 were closely related to the site from which the cephalocele issued, and @entity600 was found in eight @entity1 with parietal cephalocele. Two types of @entity3976 were found, each in a different location. The first type was an alopecic lesion occurring in the parietal midline; all five @entity1 with this type had @entity600 and none developed normally. The second type was a nodular lesion developing at the occipital midline, not associated with @entity1779 ; all five @entity1 with this type showed normal development. The pathogenesis of @entity3976 and their associated intracranial @entity600 are discussed.
