There were 36 males and 40 females,with the average age of 47.7 years.36 patients presented with sciatica and perineal numbness,11 patients had painless mass and the other 20 were identified due to other causes.Among 67 benign neurogenic tumors,54 were originated from S1-S3 nerves,3 from S4-S5 nerves and 11 from the presacral space without caudal involvement.Giant cell tumor was found in 60 patients,which included 24 males and 36 females,with an average age of 32 years.Upper sacrum（S1-S2） was involved firstly.There were 56 patients（average,37.7 years） diagnosed as other primary benign bone tumors,which included 24 cases of teratomas,epidermoid cyst or dermoid cyst.Other malignant tumors,including chondrosarcoma （17）,Ewing′s sarcoma/PNET（14）,multiple myeloma（12）,lymphoma（6） and osteosarcoma（6） were found in 64 patients.
