[Vacuolar myelopathy after allogeneic bone marrow transplantation in a patient with acute lymphoblastic leukemia].

ABSTRACT

Vacuolar myelopathy (VM) is known to be a neurological complication in patients with acquired immunodeficiency syndrome (AIDS). In autopsy-based studies, VM was reported in approximately 20-50% of patients with AIDS. It manifests in various says, mainly presenting as a painless spastic paraparesis with a sensory ataxia. We present a rare case of VM after bone marrow transplantation (BMT) in a patient without AIDS. A 50-year-old man developed weakness in the lower legs, leg muscle atrophy, and difficulty in walking 86 days after BMT. The patient died from septic shock on day 309. The autopsy revealed intralamellar vacuolation in the spinal white matter, which was compatible with VM.
