Abstract:
The case of a 38 year-old-man with a mass at the S2 level similar to a benign nerve root tumor (neuroma) is reported. The CT scan examination revealed the mass close underneath but not in connection with a disc herniation at the L5/S1 level. During operation the mass was not encountered as tumor but as free sequestered disc herniation, which was confirmed by histological examination. The reasons for considering the mass a tumor are discussed.
