Stereotactic biopsy for XXXX : comparison of approaches and reports of 10 cases.

@entity75 @entity1
BACKGROUND: Stereotactic biopsy for @entity75 offers high diagnostic yield with low morbidity. We compared two modalities of biopsy procedure, frame-based and frameless stereotaxy, either transfrontal or transcerebellar route. The benefits and operation considerations are discussed. METHODS: Ten @entity1 with intrinsic @entity75 diagnosed with stereotactic biopsy from August 2006 to March 2010 were retrospectively reviewed. All procedures were performed under general anesthesia. Six of 10 @entity1 were approached with transfrontal route, whereas the other four @entity1 with transcerebellar route. Frame-based stereotaxy or frameless navigation system was applied. RESULTS: All lesions of the 10 @entity1 were successfully diagnosed with stereotactic biopsy procedure. There was no major morbidity after the procedure. CONCLUSION: A number of approaches are available for stereotactic brainstem biopsy. Surgical approach should be tailored, according to the location neurological function, with special concern for the @entity1 ' safety. In selected condition, frameless stereotaxy biopsy also provides competed diagnostic yield.
