Background: The occurrence of spinal drop metastasis in patients diagnosed with glioblastoma multiforme (GBM) is rare. In previous reports, this diagnosis occurred after surgical resection of GBM, which was believed to increase the likelihood of tumor seeding. Diagnosis of spinal drop metastasis prior to surgery remains rare.
Case Description: We report a 57-year-old woman with a brief history of confusion, altered behavior, and agitation without any other significant past medical history. Computed tomography and magnetic resonance imaging (MRI) of the head demonstrated an intra-axial lesion of the right temporal lobe as well as evidence of leptomeningeal disease around the medulla. A spine MRI scan revealed spinal drop metastases at the level of C1 and T6/T7. Subsequent biopsy confirmed WHO-2016 grade IV GBM.
Conclusions: The awareness of the possibility of spinal drop metastasis prior to surgical resection of GBM is important. The use of routine MRI of the whole neuroaxis in patients diagnosed with GBM can aid in prognosis and management options.

In clinics, physical injuries to the spinal cord cause a temporary motor areflexia below lesion, known as spinal shock. This topic is still underexplored due to the lack of preclinical spinal cord injury (SCI) models that do not use anesthesia, which would affect spinal excitability. Our innovative design considered a custom-made micro impactor that provides localized and calibrated strikes to the ventral surface of the thoracic spinal cord of the entire CNS isolated from neonatal rats.

The mechanical properties of brain and spinal cord tissue have proven to be extremely complex and difficult to assess. Due to the heterogeneous and ultra-soft nature of the tissue, the available literature shows a large variance in mechanical parameters derived from experiments. In this study, we performed a series of indentation experiments to systematically investigate the mechanical properties of porcine spinal cord tissue in terms of their sensitivity to indentation tip diameter, loading rate, holding time, ambient temperature along with cyclic and oscillatory dynamic loading.

Background Context: Spinal cord injury (SCI) causes neural circuit interruption and permanent functional damage. Magnetic stimulation in humans with SCI aims to engage residual neural networks to improve neurological functional, but the detailed mechanism remains unknown.
Purpose: This study evaluates functional recovery and neural circuitry improvements in rodent with double-target (brain and spinal cord) magnetic stimulation (DTMS) treatment and explores the effect of DTMS on the modulation of glial cells in vivo and in vitro.

Background: The analysis of epidural procedure utilization has revealed several notable trends over recent years. Utilization increased significantly until 2004, then rose minimally until 2011, followed by gradual declines up to 2019 in the Medicare population. The COVID-19 pandemic led to a marked 19% decline in usage from 2019 to 2020.

There are few published descriptions of the MRI appearance of canine intracranial or spinal cord ependymoma. In this multicenter, retrospective, secondary analysis, case series study, three veterinary radiologists independently reviewed and recorded imaging characteristics of MRI studies in six dogs with histopathologically confirmed ependymoma (three intracranial and three spinal cord cases). A consensus was reached when there was disagreement on specific features.
