OBJECTIVE: The objective of this study was to evaluate the characteristics and surgical outcome of the @entity5 . METHODS: We retrospectively reviewed 26 @entity1 who underwent surgery for @entity5 from August 1986 to July 2007. We analyzed clinical manifestation, preoperative MRI findings, extent of surgical resection, histopathologic type, adjuvant therapy, and outcomes. RESULTS: There were @entity424 (13), @entity279 (3), @entity362 (3), @entity816 (3), primitive @entity4969 (PNET) (2), mature @entity44 (1), and @entity8702 (1) on histopathologic type. @entity158 was the most common symptom and was seen in 80.8% of @entity1 . @entity158 or sensory change in the saddle area was seen in 50% of @entity1 and 2 @entity1 had severe @entity158 in the perineum and genitalia. Gross total or complete @entity5 resection was obtained in 80.8% of @entity1 . On surgical outcome, modified JOA score worsened in 26.9% of @entity1 , improved in 34.6%, and remained stable in 38.5%. The mean VAS score was improved from 5.4 to 1.8 among 21 @entity1 who had @entity615 and @entity158 . CONCLUSION: The surgical outcome of @entity5 mainly depends on preoperative @entity16 and pathological type. The surgical treatment of @entity5 needs understanding the anatomical and functional characteristics of @entity5 for better outcome.
