Variations of Intracranial Dural Venous Sinus Diameters from Birth to 20 Years of Age: An MRV-Based Study

ORIGINAL RESEARCH PEDIATRICS Variations of Intracranial Dural Venous Sinus Diameters from Birth to 20 Years of Age: An MRV-Based Study A.S. Larson, G. Lanzino, and W. Brinjikji ABSTRACT BACKGROUND AND PURPOSE: The role of the dural venous sinus system in cerebrovascular pathology and the understanding of normal developmental patterns and sizes of the dural venous sinus system continue to expand. The purpose of this study was to review MR venograms to elucidate developmental patterns and diameters of the major dural venous sinuses from 0 to 20 years of age. MATERIALS AND METHODS: All available MR venograms of patients 0–20 years of age who presented to our institution were ret- rospectively reviewed. Patient age at the time of image acquisition was noted, and measurements were taken of the diameters of the major dural venous sinuses. The presence of embryonic sinuses including the persistent falcine sinus and the occipital sinus was noted. Dominance patterns of the transverse sinus system were determined. Mean diameters of each sinus were plotted as a func- tion of age. The prevalence of persistent prenatal sinuses and transverse sinus–dominance patterns was compared across ages. RESULTS: A total of 429 MR venograms from 429 patients were reviewed.
