title: Giant intrasacral schwannoma: an unusual cause of lumbrosacral radiculopathy.
abstract: Sacral schwannoma is a rare lesion (23 reported cases) with a tendency to reach large proportions. Symptoms are back and leg pain, leg weakness, hypoesthesias, paresthesias, constipation, and incontinence. The peak incidence is between ages 30 and 50. Radiographs of the sacrum are abnormal in nearly all cases. Computed tomography and magnetic resonance imaging may reveal large lesions with bony erosion and involvement of the soft tissues. The treatment of this lesion is complete removal, which is curative.
