Abstract
We present a case of death likely to be directly due to cyclosporine (CsA) neurotoxicity. To date, there have been no reports of deaths directly due to CsA neuro- toxicity, nor has an associated histological lesion been described independent of confounding processes. A 54-year-old male received an HLA-matched-unrelated BMT for CML. He developed progressive encephalo- pathy and on day +79 had a generalized seizure. All CSF studies were negative for infectious causes. MRI revealed diffuse, symmetrical white matter abnormalities located in the occipital sub-cortex, thalamus, mid brain, pons, and cerebellum which were typical of CsA toxicity. The patient died of central respiratory failure within 72 h of discontinuing CsA. Autopsy revealed diffuse patchy white matter edema and astrocytic injury without evidence of axonopathy, demyelination, microvascular injury, or infectious/inflammatory process. This case demonstrates previously undescribed lethal CsA neurotoxicity and may reveal an associated primary pathological lesion.
