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

Spinal cordectomy for the management of thoracic malignant intraspinal tumors in paraplegic or irreversibly, severely paraparetic patients: A technical remark.

J Clin Neurosci 2019 Oct 18;68:308-311. Epub 2019 Jul 18.

IRCCS, "Neuromed", Via Atinense 18, 86077 Pozzilli, IS, Italy.

Background: Malignant Intramedullary Spinal Cord Tumor are a relatively uncommon entity affecting patients whose prognosis is quickly and relentlessly dismal. Since the '50s Spinal Cordectomy' has been advocated for the surgical management of these conditions, but to date, no standard operative protocol has been reported yet.

Objective: Although apparently "easy", burdened by virtually no further risk for the neurological function in paraplegic or severely paraparetic patients, SCt conceals notable pitfalls and surgical problems that are to date not yet completely discussed. 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

Accuracy of intraoperative pathological diagnosis using frozen sections of spinal cord lesions.

Clin Neurol Neurosurg 2018 04 16;167:117-121. Epub 2018 Feb 16.

Department of Orthopedic Surgery, Nagoya University Graduate School of Medicine, 65 Tsurumai Showa-ward, Aichi, Nagoya, 466-8550, Japan. Electronic address:

Objectives: Frozen sections are used to provide gross and rapid microscopic pathological information for guidance on intraoperative management and therapeutic decision-making. Many studies have shown the accuracy of frozen section diagnosis for intracranial lesions, but there are no studies focusing on spinal cord lesions.

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.

Malignant Spinal Cord Compression: Adapting Conventional Rehabilitation Approaches.

Phys Med Rehabil Clin N Am 2017 02;28(1):101-114

Department of Neurology, Rehabilitation Medicine Service, Memorial Sloan Kettering Cancer Center, Sillerman Center for Rehabilitation, 515 Madison Avenue, 5th Floor, New York, NY 10022, USA; Division of Rehabilitation Medicine, Weill Cornell Medical College, 525 East 68th Street, New York, NY 10065, USA. Electronic address:

Spinal tumors are classically grouped into 3 categories: extradural, intradural extramedullary, and intradural intramedullary. Spinal tumors may cause spinal cord compression and vascular compromise resulting in pain or neurologic compromise. They may also alter the architecture of the spinal column, resulting in spinal instability. Read More

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

Surgical management of ventral intradural spinal lesions.

J Neurosurg Spine 2011 Jul 15;15(1):28-37. Epub 2011 Apr 15.

Columbia University College of Physicians and Surgeons, Department of Neurological Surgery, New York, New York, USA.

Objective: Access to the ventral intradural spinal canal may be required for treatment of a variety of lesions affecting the spinal cord and adjacent intradural structures. Adequate exposure is usually achieved through a standard posterior laminectomy or posterolateral approaches, although formal anterior approaches are used to access lesions in the subaxial cervical spine. Modifications of the standard posterior exposure as well as ventral or ventrolateral approaches are increasingly being used for treating intradural spinal pathologies. Read More

Intramedullary spinal cord hemorrhage (hematomyelia).

Rev Neurol Dis 2009 ;6(2):E54-61

Department of Neurology, Mayo Clinic College of Medicine, Rochester, MN, USA.

Intramedullary spinal cord hemorrhage (hematomyelia) is an uncommon cause of myelopathy and can present in an acute, subacute, stepwise, or chronic fashion. Spinal vascular malformations such as intramedullary cavernomas and intradural arteriovenous malformations are the most common cause of atraumatic intramedullary spinal cord hemorrhage based on the existing literature. Additional considerations include warfarin or heparin anticoagulation, hereditary or acquired bleeding disorders, primary spinal cord tumors, spinal cord metastases, Gowers' intrasyringal hemorrhage, or a delayed complication of spinal radiation.
