A 10-year-old girl with M2 acute myeloid leukemia underwent an unrelated cord blood transplantation in refractory first relapse. On day +13, after 48 hours with fever, she showed a measles-like rash, and on day +15, she began experiencing neurologic symptoms (headache, tremors, weakness, nystagmus, mild confusion, speaking, taste, and behavior disturbances, and focal seizures). She also had amnesia for recent events with disability to learn, mimicking Wernicke-Korsakoff syndrome. Computed tomography of the brain and cerebrospinal fluid (CSF) and electroencephalogram were nonspecific. We found human herpesvirus 6 (HHV-6) DNA in CSF and cytomegalovirus in bronchoalveolar lavage using polymerase chain reaction techniques. Treatment with ganciclovir and foscarnet was effective, with total resolution of symptoms.

A 33-year-old woman with Wernicke's encephalopathy (WE) due to poor oral intake after allogeneic stem cell transplantation for acute myeloid leukemia showed a sequential development of bilateral gaze-evoked nystagmus (GEN), rightward gaze palsy, and upbeat nystagmus. Initial MRIs obtained when she had GEN only showed a lesion involving the medullary tegmentum, and follow-up MRIs revealed additional lesions in the pontine and midbrain tegmentum along with development of rightward gaze palsy, and finally bilateral medial thalamus lesions in association with upbeat nystagmus. The evolution of abnormal ocular motor findings and serial MRI changes in our patient with WE provide imaging evidence on relative vulnerability of the neural structures, and on the progression of lesions and ocular motor findings in thiamine deficiency.
