CISS images show the absence of right Meckel's cave (arrow) in the axial plane (
A
) and coronal plane (
B
). Hypoplastic cisternal segment of the right trigeminal nerve is seen in the coronal plane (arrow) (
C
).

The absence of Meckel's cave with atrophy of the cisternal segment of the trigeminal nerve on the affected side was reported ( Figs. 1 and 2 ).
(
A
) A coronal T2 weighted image demonstrates the absence of Meckel's cave on the right side (arrow). Coronal (
B
) and axial (
C
) reformats of 3D contrast enhanced T1 magnetization-prepared rapid gradient-echo (MPRAGE) show the absence of the right Meckel cave with collapsed enhancing dura without an underlying lesion (arrow).
