“…The defined upper limit of the normal interhemispheric fissure width ranges from 6 to 8.5 mm, while the similar spectrum for sinocortical width is 2 to 10 mm [56, 59, 69, 94, 99, 131]. Sinocortical width is defined as the distance from the lateral wall of the superior sagittal sinus to the surface of the cerebral cortex [56, 99].…”

Benign external hydrocephalus: a review, with emphasis on management

et al. 2011

Benign external hydrocephalus in infants, characterized by macrocephaly and typical neuroimaging findings, is considered as a self-limiting condition and is therefore rarely treated. This review concerns all aspects of this condition: etiology, neuroimaging, symptoms and clinical findings, treatment, and outcome, with emphasis on management. The review is based on a systematic search in the Pubmed and Web of Science databases. The search covered various forms of hydrocephalus, extracerebral fluid, and macrocephaly. Studies reporting small children with idiopathic external hydrocephalus were included, mostly focusing on the studies reporting a long-term outcome. A total of 147 studies are included, the majority however with a limited methodological quality. Several theories regarding pathophysiology and various symptoms, signs, and clinical findings underscore the heterogeneity of the condition. Neuroimaging is important in the differentiation between external hydrocephalus and similar conditions. A transient delay of psychomotor development is commonly seen during childhood. A long-term outcome is scarcely reported, and the results are varying. Although most children with external hydrocephalus seem to do well both initially and in the long term, a substantial number of patients show temporary or permanent psychomotor delay. To verify that this truly is a benign condition, we suggest that future research on external hydrocephalus should focus on the long-term effects of surgical treatment as opposed to conservative management.

“…The subarachnoid space in infancy has been measured by computed tomography (Pedersen, et al, 1976), magnetic resonance imaging (McArdle et al, 1987), and ultrasound (Govaert et al, 1989). In children normal standards have been determined (Libicher and Troger, 1992).…”

“…8 A small (nine cases) series of neonates examined with a 10 MHz transducer by Govaert and associates exhibited a range of values for the sinocortical width of up to 2 mm, similar to the results reported here. 1 In the most comprehensive study to date, Libicher and coauthors studied 89 infants, most of whom were older than those in our study (mean age, 105 days; no neonates) with a 5 MHz transducer. 2 Their results suggested 95th percentile measurements of 3 mm for the sinocortical width and 4 mm for craniocortical width.…”

Prominence of the extraaxial space occasionally is encountered in infants referred for ultrasonography to exclude hydrocephalus. The interpretation of this finding can be problematic. We examined the width of the extraaxial compartment in 82 normal newborn infants. Scanning technique was optimized for viewing the near field, and the extraaxial space was measured over the cerebral convexities. Correlation was made with demographic variables. Measurements varied from 0 to 3.3 mm (mean, 1.6 mm), with slight negative linear relationship to gestational age. We conclude that small amounts of extraaxial fluid, up to 3.3 mm in width on scans, are common and normal in newborn infants.
