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

Cauda equina schwannoma presenting with intratumoral hemorrhage and intracranial subarachnoid hemorrhage.

J Neurosurg Spine 2014 Sep 13;21(3):357-60. Epub 2014 Jun 13.

Department of Neurosurgery, Louisiana State University Health Sciences Center-Shreveport, Shreveport, Louisiana.

The authors report the case of a spinal intradural schwannoma presenting with intracranial subarachnoid hemorrhage (SAH). Cerebral angiography did not show any intracranial lesion; however, MRI revealed two separate tumors in the lower segment of the spinal cord. The proximal lesion arising from the conus medullaris was well circumscribed and homogeneously enhanced, whereas the tumor in the cauda equina revealed hemorrhagic signals on MRI. Read More
