Mobile Schwannomas of lumbar spine: A diagnostic dilemma

Abstract Mobile Schwannoma is a very rare entity and is reported sparsely in literature, with most of them occurring in lumbar spine region. We present a case of seventy-year-old male patient who had pain in lower back radiating to ipsilateral thigh. A diagnosis of migratory tumour was made based on findings of plain and contrast MRI preoperatively. We did a two level laminectomy and tumour excision. In this report, we intend to discuss various likely causes of tumour migration and various diagnostic methods to tackle this surgical dilemma, we have also attempted to review the sparse literature available till date on migratory lumber schwannoma.
