Focal necrotizing brain stem encephalopathy and cranial radiculopathy in a kidney transplant recipient.
A 48-year-old female patient developed sensory and motor palsy of the V-Xth cranial nerves immediately after kidney transplantation due to terminal uremia. A second exacerbation followed about 4 weeks later. After 46 days post transplantation she died from bronchopneumonia. Autopsy showed multiple acute and subacute necrotic foci in proximal portions of the cranial nerves as well as a discontinuous necrotizing encephalopathy localized mainly in the subpial zone of the brain stem. The mechanism by which lesions of the nervous system were produced remains speculative. A possible neurotoxic role was attributed to the drugs administered after transplantation. Herpes virus hominis antigen could be demonstrated in the cells of the pons and of the trigeminal ganglion, but its presence was thought to be coincidental and probably not causally related to the described lesions.
