Ki-1-positive anaplastic large cell lymphoma is a common form of aggressive non-Hodgkin's lymphoma in children with a wide spectrum of clinical presentations. Uncommonly, it presents as a paraspinal tumour with spinal cord compression. Only a limited number of cases with similar presentation have so far been reported in the English literature. We reported a boy with paraspinal Ki-1-positive anaplastic large cell lymphoma initially presented with paraplegia. The patient achieved complete remission with chemotherapy plus local irradiation and regained full function with no residual neurological deficit.
