title: Giant intrasacral schwannoma forming a presacral mass: a report of an unusual cause of lumbosacral radiculopathy.
abstract: Schwannomas are extremely rare tumours deriving from cells within the neurilemma. The authors report a case of giant intrasacral schwannoma presenting in the presacral region. The tumour presented with a lumbosacral pain and it was removed totally by two-stage surgical intervention. When seen five years after the second surgical intervention, the patient was asymptomatic. The rarity of such cases prompted this report.
