Lumbar spinal intraosseous schwannoma: a non-operative approach

Intraosseous schwannomas are benign tumours composed of nerve sheath cells, most commonly affecting the mandible and sacrum. Such intraosseous schwannomas in the vertebra can result in spinal instability causing deformity, pain and even neurological compression. Vertebral involvement in the lumbar spine is extremely rare. A case of a schwannoma of the lumbar spine at the level of L3/L4 is presented. It resulted in progressive lower back pain and right lower limb radiculopathy. The clinical findings, radiological reports and histological diagnosis of this case, along with a review of the literature, are presented. The rationale for non-surgical management of this rare benign tumour is also explored.
