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 Oct;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

MR imaging features that distinguish spinal cavernous angioma from hemorrhagic ependymoma and serial MRI changes in cavernous angioma.

J Neurooncol 2016 10 16;130(1):229-236. Epub 2016 Aug 16.

Department of Radiology, Spine and Spinal Cord Institute, Gangnam Severance Hospital, Yonsei University College of Medicine, 211 Eonju-ro, Gangnam-gu, Seoul, 135-720, South Korea.

Cavernous angiomas of the spinal cord exhibit imaging characteristics that may overlap with those of hemorrhagic ependymoma. In the present study, we aimed to identify specific magnetic resonance imaging (MRI) findings that could be used to differentiate cavernous angioma from hemorrhagic ependymoma, and to evaluate serial MRI changes in cases of cavernous angioma. We retrospectively evaluated MR images of spinal cord tumors collected at our hospital from 2007 to 2015. Read More

Neuroimaging of spine tumors.

Handb Clin Neurol 2016 ;136:689-706

Dent Neurologic Institute, Amherst, NY, USA. Electronic address:

Intramedullary, intradural/extramedullary, and extradural spine tumors comprise a wide range of neoplasms with an even wider range of clinical symptoms and prognostic features. Magnetic resonance imaging (MRI), commonly used to evaluate the spine in patients presenting with pain, can further characterize lesions that may be encountered on other imaging studies, such as bone scintigraphy or computed tomography (CT). The advantage of the MRI is its multiplane capabilities, superior contrast agent resolution, and flexible protocols that play an important role in assessing tumor location, extent in directing biopsy, in planning proper therapy, and in evaluating therapeutic results.

Quantitative imaging analysis of posterior fossa ependymoma location in children.

Childs Nerv Syst 2016 Aug 27;32(8):1441-7. Epub 2016 Apr 27.

Department of Diagnostic Imaging, St. Jude Children's Research Hospital, 262 Danny Thomas Place (MS 220), Memphis, TN, 38105, USA.

Purpose: Imaging descriptions of posterior fossa ependymoma in children have focused on magnetic resonance imaging (MRI) signal and local anatomic relationships with imaging location only recently used to classify these neoplasms. We developed a quantitative method for analyzing the location of ependymoma in the posterior fossa, tested its effectiveness in distinguishing groups of tumors, and examined potential associations of distinct tumor groups with treatment and prognostic factors.

Methods: Pre-operative MRI examinations of the brain for 38 children with histopathologically proven posterior fossa ependymoma were analyzed. Read More

Lumbar corpectomy for correction of degenerative scoliosis from osteoradionecrosis reveals a delayed complication of lumbar myxopapillary ependymoma.

J Clin Neurosci 2016 Aug 4;30:160-162. Epub 2016 Apr 4.

University of Arizona, Department of Surgery, Division of Neurosurgery, 1501 N. Campbell Avenue, Tucson, AZ 85724-5070, USA.

Osteoradionecrosis is a known complication following radiation therapy, presenting most commonly in the cervical spine as a delayed consequence of radiation that is often necessary in the management of head and neck cancers. In contrast, osteoradionecrosis has rarely been described in the lumbar spine. Here we describe, to our knowledge, the first reported case of lumbar spine osteoradionecrosis, after adjuvant radiation for a primary spinal cord tumor, leading to progressive degenerative scoliosis which required subsequent operative management.
