Introduction: The lumbar disc herniations are seen very common than spinal ependymomas in the neurosurgery polyclinic routine.
Presentation Of Case: In our case, both pathologies were seen at the most frequently located levels compatible with the literature. Aim of this case report is, to remind once more that, different pathologies can be found at the same time in a single patient; differential diagnosis must be done very carefully.
Discussion: The routine Computed Tomography (CT) imaging for low back pain can not show the conus medullaris pathology. Spinal tumors or other similar pathologies should be kept in mind for differential diagnosis. A good medical history and a good physical examination must be completed before the final diagnosis.
Conclusion: Viewing of spinal canal with Magnetic Resonance Imaging (MRI) will be useful for the patients who we intend to do disc surgery.

Although intracranial and spinal cord meningioma prognoses have been reported, few studies have evaluated the outcomes and prognoses of orbital and optic nerve meningiomas in dogs. We aimed to evaluate the outcomes of canine orbital meningiomas. The seven dogs included were cytologically or histopathologically diagnosed with meningiomas.

An 8 yr old, male, mixed-breed dog was presented with a 2 mo history of progressive weakness, worsened in the last 2 days before examination. Neurological examination revealed ambulatory tetraparesis, ataxia, and proprioceptive deficits in all four limbs. Menace response was reduced in the right eye and discomfort was detected on neck manipulation.

Background: Spinal ependymomas are typically slow-growing tumors with a favorable prognosis. Recently, a new aggressive subtype has emerged with its own distinct histopathological and molecular features characterized by MYCN amplification. However, this subtype of spinal ependymoma is rare, and studies on its imaging characteristics are limited.

Various mature tissue-resident cells exhibit progenitor characteristics following injury. However, the existence of endogenous stem cells with multiple lineage potentials in the adult spinal cord remains a compelling area of research. In this study, we present a cross-species investigation that extends from development to injury.

Humans can perform movements in various physical environments and positions (corresponding to different experienced gravity), requiring the interaction of the musculoskeletal system, the neural system and the external environment. The neural system is itself comprised of several interactive components, from the brain mainly conducting motor planning, to the spinal cord (SC) implementing its own motor control centres through sensory reflexes. Nevertheless, it remains unclear whether similar movements in various environmental dynamics necessitate adapting modulation at the brain level, correcting modulation at the spinal level, or both.
