Diagnostic Implication and Clinical Relevance of Dermatomal Somatosensory Evoked Potentials in Patients with Radiculopathy: A Retrospective Study.

Pain Res Manag 2021 1;2021:8850281. Epub 2021 Jun 1.

Department of Physical Medicine & Rehabilitation, Jeonbuk National University Medical School, Jeonju 54907, Republic of Korea.

Objective: Dermatomal somatosensory evoked potentials (DSEPs) are used to evaluate abnormalities of the somatosensory tract. There have been some studies on the diagnostic value of DSEP in radiculopathy, but it is still controversial. The purpose of our study is to evaluate the diagnostic implication and clinical relevance of DSEPs in patients with radiculopathy by comparing DSEP findings to radiculopathy symptoms and intervertebral foramen (IVF) or spinal canal stenosis in lumbar magnetic resonance imaging (MRI).

Brain Nerve 2021 Jun;73(6):715-724

Department of Neurology, Teikyo University School of Medicine.

Magnetic resonance imaging (MRI) is widely employed in the diagnosis of lumbar spine disorders, such as lumbar spinal stenosis or lumbar disc herniation. However, incomplete specificity is a definite drawback, given that MRI abnormalities are frequently identified in aged control subjects. Relying solely on MRI without considering clinical symptoms/signs or electrodiagnosis may lead to misdiagnosis. Read More

[Early Diagnosis of Spinal Dural Arteriovenous Fistula].

Brain Nerve 2021 Jun;73(6):685-696

Department of Neurology, Anjo Kosei Hospital.

Spinal dural arteriovenous fistulas (SDAVF) are rare and most commonly affect men aged >50 years. Patients with SDAVF develop an abnormal vascular dural shunt between the dural branch of a segmental artery and a subdural radicular vein that drains the perimedullary venous system, leading to venous hypertension and secondary congestive myelopathy. Most SDAVFs are located in the thoracolumbar region, and usually patients present with slowly progressive paraparesis and urinary disturbances. Read More
