Prior to tumor resection the spine was instrumented with pedicle screws at T3-T12 on the right side and at T3 T4 T11 and T12 on the left side. Tumor resection was performed along the indicated lines. The en bloc resection was done with serial contralateral lami-notomies at T5-T10 e ipsilateral pedicle osteotomies at T5-T9 and rib osteotomies at T5-T10.
