title: Association of persistent falcine sinus with different clinicoradiologic conditions: MR imaging and MR angiography.
abstract: Nine pediatric patients are reported with persistent falcine sinuses associated with a variety of clinicoradiologic conditions and disorders. Besides MR imaging studies four patients had MR angiography examinations. Persistent falcine sinus was associated with arteriovenous malformations in three patients. In two cases persistent falcine sinus was an incidental finding. In the remaining four patients persistent falcine sinus was associated with total absence of the corpus callosum, acrocephalosyndactyly (Apert's syndrome), osteogenesis imperfecta, Chiari II malformation. The straight sinuses were either absent or rudimentary or entirely normal in these cases. It can be concluded that a mesenchymal disorder can be the primary cause for an open falcine sinus either in isolation or in association with variable changes in the straight sinus.
