A giant schwannoma of cauda equina

A case of giant schwannoma occurring in a woman 23 years of age with deformity of the foot developing at the age of five years is reported. The gross radiological changes of increased interpedicular distance and erosion of the posterior surface of the vertebra suggested the massive size of the tumour (6'' x 21/2'' x 11/2''). Successful surgical excision of such a large size schwannoma has not been reported previously.
