Atypical Neurologic Complications Post Autologous Stem Cell Transplantation

Abstract

We describe the case of a patient with high grade, triple hit, Non-Hodgkin’s Lymphoma (NHL) who underwent high-dose chemotherapy and Autologous Stem Cell Transplantation (ASCT) as a consolidation. Patient received BEAM conditioning regimen. She engrafted after usual post ASCT course. However, 2 months post ASCT she developed atypical neurologic symptoms and findings leading to general weakness mainly in the lower extremities with multiple falls, mental status changes and high CSF protein with severe sensorimotor neuropathy. She initially failed treatment with IVIg but responded to high dose steroids. More than one year after transplant, she has maintained her neurological improvement, but unable to walk, while her NHL continues to be in remission.
