Acquired post-traumatic CSF fistulas in two different patients. Coronal bone (a) and soft tissue (b) CT images demonstrate a tiny bony defect of the right cribriform plate (arrow, a) and abnormal opacification of the right olfactory recess on the soft tissue window (arrow, b). The coronal T2WI MRI image of the same patient confirms herniation of fluid intensity CSF into the right olfactory recess consistent with a meningocele (arrow, c). For comparison, coronal T2WI MRI image of another patient (d) demonstrates herniation of both the gyrus rectus and CSF consistent with a meningoencephalocele (arrow, d)
