Stereotactic Radiation for Treating Primary and Metastatic Neoplasms of the Spinal Cord.

Front Oncol 2020 9;10:907. Epub 2020 Jun 9.

Departments of Radiation Oncology, NYU Grossman School of Medicine, New York, NY, United States.

Stereotactic radiation treatment can be used to treat spinal cord neoplasms in patients with either unresectable lesions or residual disease after surgical resection. While treatment guidelines have been suggested for epidural lesions, the utility of stereotactic radiation for intradural and intramedullary malignancies is still debated. Prior reports have suggested that stereotactic radiation approaches can be used for effective tumor control and symptom management. Read More

Intradural Extramedullary Nonconus Nonfilum Spinal Ependymomas: Report of a Rare Variant and Newer Insights into Their Histogenesis with Proposal of a Classification Scheme and a Management Algorithm Based on a Review of Literature.

World Neurosurg 2020 Feb 1;134:323-336. Epub 2019 Nov 1.

Department of Neurosurgery, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India.

Background: Ependymomas are common intramedullary spinal tumors but there are scattered reports of this tumor presenting with exophytic growth patterns masquerading as intradural extramedullary (IDEM) tumors. Such IDEM ependymomas are seldom suspected preoperatively and it is only during surgery that their existence is revealed. Little is known of such rare growth patterns of an otherwise common intramedullary spinal cord tumor, their characteristics, and their management considerations. Read More

A mini-open transspinous approach for resection of intramedullary spinal cavernous malformations.

J Clin Neurosci 2018 Dec 13;58:210-212. Epub 2018 Oct 13.

University of California San Francisco, Department of Neurological Surgery, San Francisco, CA, USA. Electronic address:

Background And Importance: Advances in minimally invasive (MIS) and mini-open surgical approaches have led to reductions in perioperative morbidity without compromising rates of resection of non-degenerative intradural spinal pathologies. Whether these approaches may be adapted for the surgical resection for intramedullary vascular malformations - such as cavernous malformations (CMs) - has yet to be reported. The authors describe a mini-open transspinous approach to resect a ruptured intramedullary CM of the conus medullaris. Read More

Intradural spinal tumors in adults-update on management and outcome.

Neurosurg Rev 2019 Jun 17;42(2):371-388. Epub 2018 Feb 17.

Department of Neurosurgery, Vivantes Klinikum Neukölln, Berlin, Germany.

Among spinal tumors that occur intradurally, meningiomas, nerve sheath tumors, ependymomas, and astrocytomas are the most common. While a spinal MRI is the state of the art to diagnose intradural spinal tumors, in some cases CT scans, angiography, CSF analyses, and neurophysiological examination can be valuable. The management of these lesions depends not only on the histopathological diagnosis but also on the clinical presentation and the anatomical location, allowing either radical resection as with most extramedullary lesions or less invasive strategies as with intramedullary lesions.

Thoracic exophytic ependymoma masquerading as a benign extra-axial tumor.

J Clin Neurosci 2016 Nov 28;33:221-225. Epub 2016 Aug 28.

Department of Neurosurgery, Massachusetts General Hospital, 55 Fruit Street, Boston, MA 02114, USA. Electronic address:

Spinal tumors are conventionally differentiated based on location in relation to the spinal cord. Benign spinal tumors such as schwannomas and meningiomas are typically extra-axial (intradural extramedullary) lesions, whereas more aggressive primary spinal tumors such as ependymomas are typically intramedullary masses. Rarely, ependymomas can have both intramedullary and extramedullary components (typically referred to as exophytic ependymomas). Read More

The application of surgical cordectomy in the management of an intramedullary-extramedullary atypical meningioma: case report and literature review.

J Spinal Disord Tech 2005 Oct;18(5):449-54

Department of Neurosurgery, Johns Hopkins Hospital, Baltimore, MD, 21287, USA.

Background: The English literature describes only four cases of intraspinal tumors requiring surgical intervention in the form of cordectomy; none of these cases was for meningiomas. Intraspinal meningiomas, typically extramedullary-intradural, require treatment in the form of resection with dural margin excision. The presentation of an intramedullary atypical World Health Organization grade II meningioma is rare. Read More

Spinal cord and intradural-extraparenchymal spinal tumors: current best care practices and strategies.

J Neurooncol 2004 Aug-Sep;69(1-3):291-318

Department of Neurological Surgery, University of California, San Francisco, CA 94143, USA.

The management of patients with intradural spinal tumors differs in many respects from approaches taken for patients with intracranial tumors. Intramedullary lesions are often completely surrounded by normal spinal cord, displacing vital functional tracts eccentrically. Extramedullary lesions can drastically compress the spinal cord and nerve roots, reducing normal tissue to a ribbon-like consistency. Read More

MRI in the diagnosis and treatment of suspected malignant spinal cord compression.

Br J Radiol 2001 Jan;74(877):15-23

Clatterbridge Centre for Oncology, Clatterbridge Road, Bebington, Wirral CH63 4JX, UK.

It remains unclear whether MRI is essential in all patients with suspected malignant spinal cord compression (MSCC), or whether some patients can be treated on the basis of plain radiographic findings and neurological examination. A prospective study was carried out of 280 consecutive patients with suspected MSCC, and the results of neurological examination plus plain radiographs were compared with MRI. 201 patients had MSCC (186 extradural, 5 intradural extramedullary and 10 intramedullary) and 11 patients had thecal sac compression without evidence of spinal cord compression.

Pediatric spinal axis tumors.

Neurosurg Clin N Am 1992 Oct;3(4):947-58

Department of Neurosurgery, Memorial Sloan-Kettering Cancer Center, New York, New York.

Pediatric spinal cord tumors occur in the intramedullary or extramedullary spaces. The extramedullary tumors are further divided into those in intradural-extramedullary or extradural locations. Tumors in the intradural-extramedullary region include nerve sheath tumors, meningiomas, and "embryonal" tumors. Read More

Magnetic resonance imaging of spinal cord hemangioblastomas and arteriovenous malformations.

Acta Radiol Suppl 1986 ;369:730-3

Institute of Clinical Radiology, University of Münster, Medical School, West Germany.

Eight patients with either spinal cord hemangioblastomas (n = 5), spinal arteriovenous malformations (AVM) (n = 2) and intramedullary hematoma (n = 1) were studied by magnetic responance (MR) imaging. All hemangioblastomas, one AVM and the intramedullary hematoma were identified by MR. Compared with other neuroradiologic procedures, MR provided important complementary information in the diagnostic management of spinal hemangioblastomas and proved to be a useful method for noninvasive follow-up in these lesions.

Intramedullary cystic teratoid tumor of the cervical spinal cord in association with a teratoma of the ovary.

Surg Neurol 1984 Sep;22(3):267-72

A 15-year-old black female student came to the hospital because of disturbance of her gait. On examination, there was a dermal sinus in the skin overlying the spine of the seventh cervical vertebra, and myelography with computed tomography scan demonstrated a block to the flow of metrizamide contrast material at T-5 with cephalad extension of an intradural cystic lesion to the C-5 level. An x-ray examination of the abdomen at the time demonstrated a tooth-shaped radiodensity in the left hypogastrium. Read More

Pain in children with spinal cord tumors.

Childs Brain 1984 ;11(1):36-46

Pain in children is generally not accorded the same significance by allied health professionals as pain in adults. To some extent this relative neglect may be the result of a general belief that pain is less of a problem in the pediatric age-group. However, it is the author's experience that the management of pain in children with spinal cord tumors reveals the same significance as in adults. Read More
