Normal cranial nerve V enhancement is seen as a result of what factors?
Related to: - suboptimal imaging parameters - venous plexus enhancement, or - a combination of the two.
Thin axial T2-weighted images of the cranial nerve V course shows no evidence for vascular compression or mass lesion, particularly on the right side.
Upon contrast administration, avid enhancement of the intracranial right trigeminal nerve from its origin at the pons, at its cisternal segment, to the trigeminal ganglion and likely at the cavernous sinus is appreciated.
There is also abnormal enhancement of the meninges along the right Meckel's cave. The left trigeminal nerve course shows no abnormal signal change or enhancement.
