case_images: Trigeminal neuralgia due to varicella zoster virus reactivation. Brain MRI demonstrated a longitudinal lesion with hyperintense signal on T2-weighted imaging in the left spinal nucleus of the trigeminal nerve, in the coronal (arrow in A) and axial (arrow in B) planes and on an axial FLAIR (arrow in C), associated with gadolinium enhancement in the cisternal segment of the left trigeminal nerve (arrow in D). PCR of a cerebrospinal fluid sample revealed VZV positivity.

case_images: Brain magnetic resonance imaging (MRI) revealed a longitudinal lesion with a hyperintense signal on T2-weighted imaging in the left posterolateral portion of the pons and medulla oblongata along the left spinal nucleus of the trigeminal nerve, associated with gadolinium enhancement in the cisternal segment (Figure 1).
