Did you do VZV PCR on spinal fluid?

He also had an episode of aplastic anaemia (spontaneous recovery) along with dysgammaglobulinaemia (now on IVIG) and NK cell dysfunction.

He has evidence of old infarcts on MRI (c. 2 years), suggesting an indolent process, but with normal clinical neurology.  His CSF protein is grossly elevated with a mild lymphocytic pleiocytosis.  We do not yet have EBV PCR from his CSF but he has been consistently negative from other tissues, and nor do we have pre-IVIG EBV serology.

We are treating him initially with steroids and anti-platelet dose aspirin, and if he is shown to be EBV positive we would use rituximab. We are typing him for HSCT, however there is no real guidance in the literature on successful definitive treatments.
