  • protrusions of the optic nerve head mainly on the right 
  • Partially empty sella turcica
  • enlarged Meckel cave mainly on the left
  • the cerebral venous sinuses are patent on postcontrast sequences with stenosis in distal portions of both transverse sinuses on MRV images
  • No mass lesion at infra-or supra-tentorial regions
