case_images: At 22 months of age, the Neurosurgery and Orthopedic Surgery Oncology teams performed low sacral amputation and en bloc resection of the tumor through a posterior approach (Fig 1).
case_images: Intraoperative photographs. Patient is positioned prone with head oriented to the right. Hash marks on right buttock indicate area that was de-epithelialized and inset into wound (left). Tumor resection resulted in a complex defect with extensive dead space and projection of the rectum into the wound (right).

case_images: The resultant defect was complex: extensive dead space was formed by bony resection, gluteal and other muscles were lateralized by mass effect, multiple exposed nerve roots filled the field, the rectum projected into the wound causing concern for hernia or pseudohernia, and overlying subcutaneous and skin was inadequate (Fig 2).
