Transverse pre and post contrast T1-weighted images of the brain in patients 1-3 from rostral to caudal. Note variable severity meningeal contrast enhancement in all three patients. (A) Images at the level of the orbital fissure show intense contrast medium uptake within the orbital fissure (thin arrows). (B) Images at the level of the round foramen show increased contrast medium uptake of the maxillary branch of the trigeminal nerve bilaterally in all cases and subjective enlargement in cases 1 and 2 (red arrows). (C,D) Images at the level of the mesencephalon show enlargement and increased contrast enhancement of the trigeminal nerves (red arrows). (E,F) Images at the level of the metencephalon show increased contrast medium uptake of the facial (white arrow) and vestibulocochlear (red arrow) nerves. Note the focal left sided extraaxial lesion (corresponding to the origin of cranial nerves VII and VIII) with adjacent meningeal thickening ("dural tail sign") in case 3 (F).

Following contrast medium administration there was variable degree contrast enhancement of the orbital fissure (oculomotor, trochlear, and abducens nerves) and the optic, oculomotor, trigeminal, facial, and vestibulocochlearnerves (Figure 1, Case 3).
Sagittal post contrast t1-weighted images of the brain in case 1 (A) and case 3 (B). Both images show small contrast enhancing lesions in the cervical spinal cord (thick arrows), and evidence of meningeal enhancement (thin arrows).

There was mild multifocal meningeal contrast enhancement as well as multifocal intramedullary and meningeal enhancement associated with the cranial cervical spine (Figure 2B).
