BACKGROUND Normal displacement of the conus medullaris with unilateral and bilateral SLR has been quantified and the "principle of linear dependence" has been described. PURPOSE Explore whether previously recorded movements of conus medullaris with SLRs are i) primarily due to transmission of tensile forces transmitted through the neural tissues during SLR or ii) the result of reciprocal move...
Adolescent idiopathic scoliosis (AIS) is a structural 3-dimensional deformity the spine, which is occurring between 10 years of age and skeletal maturity and it mostly affects prepuberbal girls. The etiology of AIS remains unknown and seems should be multifactorial. According to the theories, there could be a shorter spinal cord or a higher location of the conus medullaris and disproportionate ...
Intravascular large B-cell lymphoma (IVLBCL) is a rare non-Hodgkin lymphoma with variable clinical manifestations. Although neurological symptoms are common in patients with IVLBCL, isolated cauda equina-conus medullaris syndrome is rarely reported. We herein report a case of IVLBCL whose initial presentation was cauda equina-conus medullaris syndrome with neither dermatological nor hematologic...
Figure 1 Lumbar sagittal T2-weighted (A) and post-contrast fat-suppressed T1-weighted (B) imaging shows a heterogeneous intradural mass within the conus medullaris, with a central bright signal on T2-WI and lack of contrast enhancement. Note, at the same T12—L1 level, the herniated disc that is contiguous with the mass. Figure 1 Coupes sagittales pondérées en T2 (A) et en T1 après pidermoid-cys...
To date, only a few reports described the potential factors influencing the position of conus medullaris. One previous study revealed no significant change of conus locations in patients with idiopathic scoliosis; however, the effect of ankylosing spondylitis (AS)-related thoracolumbar kyphosis on conus position remains unexplored. Therefore, we aimed to investigate the variation of conus medul...
PURPOSE In the current report, we describe a case of an extramedullary ependymoma involving a lumbar nerve root near conus medullaris. Spinal ependymomas commonly present as intramedullary tumors in the cervical or thoracic cord or as tumors arising from the conus medullaris or the filum terminale. In this case, we showed an extramedullary conus ependymoma involving a lumbar nerve root with fil...
A 47-year-old female patient who experienced urinary urgency after having stretching exercises of her legs is presented. Stretching of the legs are thought to be responsible for conus medullaris tethering which in turn causes urinary complaints. What is interesting in this case is that her complaints about urinary urgency stopped as she quit stretching exercise movements of her ...
BACKGROUND Prenatal magnetic resonance (MR) imaging demonstration of the normal spinal cord and the conus medullaris location has not been well studied. We compared balanced fast field echo (bFFE) with single-shot turbo spin-echo (SSh-TSE) MR sequences for visualizing the normal spinal cord and position of conus medullaris in fetuses. METHODS This retrospective study was approved by the Insti...
Absent F wave in the stage of spinal shock has been described in cases of traumatic spinal cord injury. The role of F wave in predicting prognosis after conus medullaris infarct has not been described. We describe herein a middle aged-man with a conus medullaris infarct. Both tibial and peroneal F waves were absent on day 4. The left tibial F wave reappeared in the following study on day 18. Al...
