True about MRI/CT appearance of lateral meningocele:

C i.e. Widened neural foramen - Lateral meningocele is non solid, CSF containing leptomeningeal outpouching through widened neural foramen usually into paraspinal, intrathoracic spaceQ. And it is generally associated with spinal deformities like, posterior (dorsal) scalloping, erosion of pedicles, thinning of neural arch & ribs, widening of spinal canal & neural foramen and kyphoscoliosis.
