“…Rasmussen et al reported that of 140 meningiomas, 130 were intradural (93%) and 10 (7%) were both intradural and extradural. 12 None was exclusively epidural. In their review of 367 cases of spinal meningiomas, Haft and Shenkin found 92% to lie intradurally; 3.5% were primarily intradural with an extradural extension, whereas only 3.5% were almost exclusively epidural.…”

“…[1][2][3] Diagnosis of schwannomas in the spinal canal is difficult because of their late growth, 4 often resulting in extensive bony destructions. Unless the integrity of the pelvic ring is restored, the patient will have difficulty in maintaining an upright posture, which will necessitate a reconstruction of the pelvic ring over time.…”

A case of pelvic ring reconstruction with a vascularized pedicle iliac bone graft for removal of a huge sacral schwannoma is reported. It is necessary to reconstruct a pelvic ring when its integrity is impaired. Spinal instrumentation is essential for a temporary stability of the pelvic ring in the course of complete healing, which at times results in instrumentation failure. Several cases of pelvic ring reconstruction using vascularized fibular bone grafts have also indicated positive results attributable to their good blood circulation, but techniques with them are relatively complicated. We applied a vascularized pedicle iliac bone graft to the pelvic ring reconstruction after resection of a huge sacral schwannoma. When a stable pelvic ring was regained by using a lumbosacral instrumentation technique, a tricortical iliac bone graft with its vascular pedicle was harvested, transported into the dead space, and tied to the right residual sacrum and the left ilium. The vascularized graft healed rapidly, and continuity of the pelvic ring was regained. This method is effective for pelvic ring reconstruction in that it does not require microvascular techniques and rapid bone healing can be obtained.

“…Within the cranium they account for 5% to 6% of all brain tumors. 2,4,7,9,10 Primary ependymomas distant from these sites are postulated to arise from the coccygeal medullary vestige or from ectopic ependymal tissue (in the case of sacrococcygeal extradural ependymomas and in the two reported cases of spinal nerve root ependymomas). 1,6,10 Either direct, hematogenous, or cerebrospinal fluid drop metastases are responsible for the reported cases of secondary ependymoma.…”
