External hydrocephalus: radiologic spectrum and differentiation from cerebral atrophy

Prevalence of Subdural Collections in Children with Macrocrania

“…2 Enlarged SS typically normalize by 2-3 years of age in BESS. 2,22,37 The patients with macrocrania and normal SS in our study may be at the later stages of this condition. There are some limitations to this study.…”

“…22 All cases of identified SDC underwent a second chart review, to include dedicated retinal examination, skeletal survey, and child abuse team (CAT) reports. Measurements of the SS were performed after qualitative assessment and after secondary exclusion.…”

Development of hydrocephalus and classical hypothesis of cerebrospinal fluid hydrodynamics: Facts and illusions

“…EH is a rare, but well documented condition in which the cerebrospinal fluid is found in excessive amounts between the dura and the brain, with mild or no brain ventricular dilatation (Anderson et al, 1984;Harbeson, 1939;Kumar, 2006;Maytal et al, 1987). Since the fluid continues to accumulate over the surface of the brain, the cerebral hemispheres are pushed toward the base of the skull (Fig.…”

A novel index in healthy infants and children — subarachnoid space: ventricle ratio

“…Pedersen et al [13] conducted a study in healthy children younger than 3 years of age by using CT and detected that interhemispheric fissure and Sylvian fissure were wider than normal. Maytal et al [10] cited an age-related external hydrocephaly in infants, which returns to normal without treatment up to 2-3 years of age with the opening of cranial sutures. In our study, SAS and VW values increased until 13 months of age and decreased in those older than 13 months of age.…”
