Giant Lumbar Dumbbell Extradural Schwannoma in a Child

Completely giant lumbar extradural spinal Schwannomas are a rare subgroup of spinal nerve sheath tumors in the pediatric age group. Single stage, single approach, complete, and safe surgical removal while preserving the spinal stability is the mainstay of treatment of giant lumbar extradural Schwannomas. In the present case, we report a case of a 9-year-old male child studying in 2(nd) standard presented with pain in both thighs and legs for 3 months. Magnetic resonance imaging lumbosacral spine showed lobulated dumbbell-shaped lesion extending from L4 superior endplate to inferior endplate of L5 in intraspinal space displacing the nerve roots. The patient underwent a posterior midline approach, L4 and L5 laminectomy and complete excision of the tumor. Histopathological confirmed the diagnosis of benign extradural dumbbell Schwannoma. Postoperatively, the child was showing gradual improvement in motor power, but his pain was significantly relieved.
