Case report: varicella-zoster virus myelitis--serial MR findings

The authors describe a 32-year-old male in whom herpes zoster of the left upper extremity was complicated by the development of cervical myelitis. Contrast enhancement and abnormal signal intensity on T1 and T2 weighted images was seen at C1-C6 levels in the spinal cord and medulla. There was also slight enlargement of the cord at these levels. On serial MR imaging the degree of enhancement changed from marked to none with corresponding clinical improvement.
