“…Specialized imaging, such as MRI, is invaluable to define a plane of cleavage between the mass and the sacrum, as well as to exclude the presence of sacrococcygeal destruction. 10 Although not available in the presented cases, endorectal ultrasound is a sensitive method for the assessment of the extent of a presacral tumor, the potential infiltration into adjacent organs, as well as for distinguishing solid lesions from cysts. 11,12 Operable lesions do not generally require preoperative biopsy.…”

Presacral tumors are particularly rare in the adult. Schwannomas are neurogenic neoplasms, rarely occurring in the retroperitoneum and the pelvis. Presented herein are the cases of 2 female patients with chronic pelvic pain who were discovered to have presacral schwannomas and were managed laparoscopically. Laparoscopy is a safe and efficient option in approaching benign pelvic tumors and might offer the advantage of better visualization of structures due to the magnification of laparoscopic view, especially in narrow anatomic spaces.

“…These tumors are heterogenous, with mixed hyperintensity and hypointensity on T2-weighted images corresponding to different cellularities, necrotic degeneration, hemorrhage, and cyst formation [5,18,19]. However, it may still be difficult to differentiate giant schwannomas from malignant peripheral nerve sheath tumors and ganglioneuromas based on imaging alone.…”

Giant invasive spinal schwannoma in children: a case report and review of the literature

et al. 2013

IntroductionGiant invasive spinal schwannoma is defined as a tumor that extends over two or more vertebral levels, erodes vertebral bodies, and extends into the extraspinal space disrupting myofascial planes. Because of its rarity, there have been few published reports describing clinical features and surgical outcomes, especially in the pediatric patient population.Case presentationWe analyzed the medical record, pathologic findings, and radiographic studies of a 14-year-old Hispanic boy who presented to Texas Children’s Hospital with a three-month history of progressive spastic paraparesis. Preoperative computed tomography and magnetic resonance imaging reports showed a large mass lesion centered at the left T7-8 neural foramen with intra- and extraspinal extension, resulting in severe spinal cord compression and vertebral body erosion, and protrusion into the retropleural space and descending aorta. Our patient underwent a single-stage posterior approach for complete resection of the tumor with reconstruction and stabilization of the vertebral column. The pathological examination was consistent with schwannoma. At the six-month follow-up, our patient had resolution of preoperative symptoms and remains neurologically intact without any radiographic evidence of recurrent tumor.ConclusionTo the best of our knowledge, our case represents the fourth child with giant invasive spinal schwannoma reported in the literature. We describe our case and review the literature to discuss the aggregate clinical features, surgical strategies, and operative outcomes for giant invasive spinal schwannoma in the pediatric age group.

“…The extent of the spinal mass is seen in sagittal, coronal, axial planes of MRI and relationship of the lesion to the neural and vascular structures is clearly delineated. 1,13,14 Giant cervical schwannomas may extend into the vertebral artery foramen, causing displacement of the vertebral artery. On imaging, delineation of the vertebral artery is required to assess its patency either by means of CT/MR angiogram or if needed, by conventional angiogram.…”

Giant erosive spinal schwannomas can be distinguished from other spinal schwannomas by its growth in myofascial planes and vertebral body erosion. Therapeutic radical tumour excision without neurologic deterioration is possible in the management. Prognosis is good after total tumour removal. In this article, it is aimed to report six patients who were diagnosed as giant erosive spinal schwannomas between 2001 and 2004 according to the criteria of Sridhar et al. Three of the patients were male and three female with the age range of 16-63 (mean age 39.7). Three of the tumours were located in the cervical region, one in the lumbar region, one in the thoracic region and one in the sacral region. Total excision of the tumours was achieved in four patients. However, one additional operation was required in two patients. Follow-up periods ranged from 6 weeks to 7 years (mean follow-up 51 months). Four patients had a good clinical outcome and there were no radiologic signs of instability or recurrence. Our experience and other published literature suggest that giant erosive spinal schwannoma has significant features such as local invasive nature together with vertebral body erosion and large size but benign histology, long duration for clinical presentation, common preoperative misdiagnosis and good prognosis after total excision. These tumours rarely need spinal instrumentation because the disc capsule and ligaments remain intact even if the pedicle and posterior elements are compromised.
