Transverse myelitis caused by herpes zoster following COVID-19 vaccination: A case report

Figure 1 Unilateral multiple crusts on an erythematous base on the right side of the lower back, corresponding to the right T6-9 dermatomes. A: Back; B: Rt. Side buttock.

Figure 2 Magnetic resonance imaging of the patient. A: Whole spine magnetic resonance imaging (T2 weighted sagittal image) shows old compression fractures of T5 and diffuse hyperintensity from T6 to T9 Level (white arrow); B: The axial image shows signal elevation centrally at the T7 Level.

Figure 3 The somatosensory evoked potentials were recorded by alternately stimulating each posterior tibial nerve at the ankle region behind the medial malleolus or the median nerve at the wrist. Two averages of 120 trials were obtained to stimulate each nerve. The somatosensory evoked potentials revealed well-developed cortical peaks for either arm. A: The principal peaks of N20 and P25 were 17 and 21 ms for both MNs; B: The peaks of both P37, N45, and N1 were delayed with the right specific in posterior tibial nerve. No side-to-side latency difference was noted.
