Caudal cell mass developmental aberrations: an imaging approach.

Clin Imaging 2018 Nov - Dec;52:216-225. Epub 2018 Jul 21.

University of Rochester Medical Center, Rochester, NY, USA.

The objective of this review is to describe antenatal and postnatal imaging criteria, which allow diagnosis and aid workup, prognostication and treatment of developmental anomalies of the caudal cell mass. The lower spinal cord (conus medullaris), filum terminale and inferior lumbar and sacral nerve roots develop from the caudal cell mass, a remnant of the embryologic primitive streak composed of undifferentiated pluripotential cells. Anomalous caudal cell mass development can manifest as tight filum terminale, caudal dysgenesis, terminal myelocystocele, anterior sacral meningocele or sacrococcygeal teratoma. Read More

Immunophenotype of myxopapillary ependymomas.

Appl Immunohistochem Mol Morphol 2013 Dec;21(6):485-9

Department of Pathology, Rush University Medical Center, Chicago, IL.

Myxopapillary ependymoma (MPE) is a slow-growing tumor occurring almost exclusively in the region of conus medullaris, cauda equina, and filum terminale. On microscopic examination, some of these tumors show solid sheets of cells with an epithelioid morphology mimicking a metastatic carcinoma. Several immunohistochemical studies addressed this issue with discordant results. Read More

Prognosis by tumor location in adults with spinal ependymomas.

J Neurosurg Spine 2013 Mar 11;18(3):226-35. Epub 2013 Jan 11.

Departments of Neurological Surgery, University of California, SanFrancisco, CA 94117 USA.

Object: Ependymomas are primary central nervous system tumors that occur more frequently in the spines of adults than they do there in children. Previous studies consist mainly of retrospective single-institutional experiences or case studies. In this study, a comprehensive literature review was performed on reported cases of spinal ependymoma treated with resection to determine whether tumor location along the spinal axis conveys important prognostic information.
