Children's Hospital of Philadelphia, Department of Neurosurgery, Philadelphia, PA, USA.

Pediatric patients presenting with intramedullary spinal cord lesions often require specific diagnoses to guide their treatment plans. Though results from magnetic resonance imaging and lumbar puncture may narrow the differential diagnosis, these tests cannot always provide a definitive diagnosis. In such cases, spinal cord biopsy may be undertaken to provide a specific histopathologic diagnosis for guiding treatment. Read More

Intradural Extramedullary Spinal Neoplasms: Radiologic-Pathologic Correlation.

Radiographics 2019 Mar-Apr;39(2):468-490

From the Department of Neuroradiology, American Institute for Radiologic Pathology, 1011 Wayne Ave, Suite 320, Silver Spring, MD 20910 (K.K.K., R.Y.S.); Department of Radiology, Mayo Clinic, Rochester, Minn (K.K.K.); Uniformed Services University of the Health Sciences, Bethesda, Md (R.Y.S.); and Department of Radiology, Walter Reed National Military Medical Center, Bethesda, Md (R.Y.S.).

While intradural extramedullary spinal disease varies widely, identification of tumors in this location and their radiologic manifestations greatly facilitates narrowing of the diagnostic considerations. Meningioma and schwannoma are the two most common intradural extramedullary tumors, and both are associated with neurofibromatosis. Meningiomas are most common in the thoracic spine and show a strong female predilection and a clinical manifestation related to compression of the spinal cord or nerve roots. Read More

Intramedullary spinal cord ependymoma and astrocytoma: intraoperative frozen-section diagnosis, extent of resection, and outcomes.

J Neurosurg Spine 2018 10;30(1):133-139

Departments of1Neurosurgery and.

OBJECTIVEThe intraoperative differentiation of ependymomas from astrocytomas is important because neurosurgical strategies differ between these two tumor groups. Previous studies have reported that the diagnostic accuracy of intraoperative frozen sections of intracranial central nervous system (CNS) tumors is higher than 83%-97%, whereas that for spinal intramedullary tumors remains unknown. Herein, authors tested the hypothesis that intraoperative frozen-section diagnosis is the gold standard for a differential diagnosis of intramedullary spinal cord tumors. Read More

Local tumor distribution in the central nervous system depends on age: among adults, ependymomas occur mostly in the spinal cord, whereas among children, intracranial manifestations are more common. To date, there are no prospective studies about treatment strategies for ependymomas. Read More

Risk factor analysis of kyphotic malalignment after cervical intramedullary tumor resection in adults.

J Neurosurg Spine 2017 Nov 8;27(5):518-527. Epub 2017 Sep 8.

Departments of 1 Orthopedic Surgery and.

OBJECTIVE A number of studies have reported that surgery for cervical intramedullary tumors via the posterior approach can result in postoperative sagittal malalignment of the cervical spine; however, the risk factors remain unclear. The purpose of this study was to investigate the changes in cervical spinal alignment after surgery for cervical intramedullary tumors in adults and to elucidate the risk factors for cervical spinal sagittal misalignment. METHODS Data for the period from April 2001 to December 2011 for all adults who had undergone surgery for cervical intramedullary spinal cord tumors at a single institution were retrospectively analyzed to determine the postoperative changes in cervical spine alignment.

Department of Neurosurgery, Oncology Education and Research Hospital, Ankara, Turkey.

Ependymomas are the most common gliomas of the conus and lower cord, with the cervical cord being the second most common location. These tumors can extend upward 3-4 vertebra, and some ependymomas can extend up over 15 segments. Depending on many factors, such as tumor size, lateralization, kyphotic deformity, and lordosis state, there are several posterior surgical options, including laminectomy, laminectomy and lateral mass screw-plate, and laminoplasty.
