A herniated disc is a condition in which the nucleus pulposus is displaced from the intervertebral space. It usually leads to back pain, thus being the most common reason for it. Patients often describe the first symptoms of a herniated disc as extreme and decisive pain. Unlike the usual mechanical back pain, a herniated disc is often related to a stinging or burning sensation that often spreads to the lower extremities and proves to be continuous at lower temperatures. We present a case of a 58-year-old male patient who visited the Acibadem City Clinic with complaints of pain initially starting from his hip, which in time extended to his left leg (L5 radiculopathy) and a few days later to his right leg (L5 radiculopathy). Before visiting the clinic, he had been treated in Germany with physiotherapy and supplements, which had proved ineffective. After an MRI, which revealed an L4-L5 herniated disc, he underwent conservative treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) and proton pump inhibitors (PPIs) for 14 days in addition to Medrol 4mg tablets (3x1 per day for 10 days). On the third day of the treatment, 60% of the symptoms had subsided. Seven months later, he came in for a scheduled checkup, and 95% of the symptoms were gone. A controlled MRI was done, and the herniated disc had completely vanished. We hope that this type of research will benefit medical professionals, patients, researchers, doctors, and students, among others. Such cases also contribute to the quality of care for such patients and help set regulated factual guidelines regarding their treatment as a whole.

Cervical myelopathy is a compressive spinal cord disease usually affecting individuals 55 and older. Involvement of C5-C7 is typical and classically presents with hand clumsiness, wide-based gait, and paresis. We present the case of a 38-year-old man with a pertinent history of a previous motor vehicle accident who presented to the emergency department for progressive numbness, weakness, and severe spasms in both lower extremities, and eventually developed bowel and bladder incontinence. Lumbar magnetic resonance imaging (MRI) showed moderate L3-L4/L5-S1 degenerative spinal changes; however, cervical MRI demonstrated severe C6-C7 spinal stenosis. The patient did not present with any upper extremity neurological changes. Given the relatively mild changes in the lumbar spine, the patient was concluded to have lower extremity and autonomic neurological issues due to severe cervical spinal stenosis. In this report, we present a relatively common case of cervical myelopathy and myelomalacia in a patient unusually presenting with no upper extremity signs and only lower extremity signs of progressive bilateral leg weakness and neurogenic urinary incontinence. This case emphasizes the importance of considering cervical spine workup in addition to thoracic and lumbar spine and conducting a comprehensive clinical neurological examination in the setting of lower extremity symptoms with progressive bilateral leg weakness and urinary incontinence.

Subacute combined degeneration (SCD) from vitamin B12 deficiency and spinal stenosis from degenerative changes may present similarly with weakness, sensory disturbances, and ataxia but require different treatments. This case report describes a 74-year-old male with suspected SCD who was discharged to an inpatient rehabilitation facility (IRF), did not improve with B12 supplementation, and later developed signs of myelopathy and diffuse joint pain. He ultimately was found to have severe cervical stenosis and pseudogout that were treated with a laminectomy and colchicine, respectively. Following surgical intervention, he returned to the IRF, where he had considerable functional improvement and was safely discharged home. This report shows the importance of recognizing the two conditions, their overlap, and the contrast between Occam\'s razor and Hickam\'s dictum.

OBJECTIVE: Neuromyelitis optica is an autoimmune disease characterized mainly by the involvement of the spinal cord and optic nerve. Clinical studies have identified the disease progression as the most important red flag. Previous researches showed that only 2% of patients with neuromyelitis optica experience a progressive course. On the other hand, neuromyelitis optica is rarely occurred in children. In the present study a case of neuromyelitis optica was reported in a female who suffered from progressive myelopathy in the course of the disease.
METHODS: The patient was a 30-year-old woman who has been affected to the disease at the age of 10 manifesting the quadriparesis. The patient also manifested optic neuritis twice. The disease became progressive at the age of 27. According to the results of the magnetic resonance imaging on spinal cord, severe atrophy was observed in the cervical and thoracic spine cord. The patient\'s antiaquaporin 4 antibody was positive.
CONCLUSIONS: Neuromyelitis optica is an astrocytopathy disease characterized by debilitating attacks. A very small percentage of patients may suffer a progressive course. According to the reported cases, this progressive course may be completely variable symptomatically, including progressive myelopathy, progressive vision impairments, and progressive cognitive impairment.

Perimedullary fistulae of the spinal cord are rare vascular lesions that can present with different clinical patterns: hemorrhage, progressive myelopathy due to arterial steal and/or venous congestion, or symptoms due to compression of neural structures by engorged vessels. Treatment consists of surgical excision, endovascular embolization, or a combination of the two. If complete obliteration of the nidus exposes the patient to undue risk of permanent neurological deficits, incomplete obliteration with reduction of the vascular supply is a reasonable compromise to improve clinical symptomatology. Partial devascularization may also alter the natural history by decreasing the risk of further growth and bleeding. In this video we illustrate the case of a patient with a perimedullary fistula of the conus treated with surgical disconnection of the main fistulous component. Partial devascularization resulted in resolution of MRI signal changes and symptoms with documented good clinical and radiological outcome and progressive regression of the residual nidus over six years of follow-up.

To report progressive motor impairment from a critically located central nervous system (CNS) demyelinating lesion in patients with restricted magnetic resonance imaging (MRI)-lesion burden.
We identified 38 patients with progressive upper motor-neuron impairment for >1 year, 2-5 MRI CNS-demyelinating lesions, with one seemingly anatomically responsible for progressive motor impairment. Patients with any alternative etiology for progressive motor impairment were excluded. A neuroradiologist blinded to clinical evaluation reviewed multiple brain and spinal-cord MRI, selecting a candidate critically located demyelinating lesion. Lesion characteristics were determined and subsequently compared with clinical course.
Median onset age was 47.5 years (24-64); 23 (61%) women. Median follow-up was 94 months (18-442); median Expanded Disability Status Scale Score (EDSS) at last follow-up was 4.5 (2-10). Clinical presentations were progressive: hemiparesis/monoparesis 31; quadriparesis 5; and paraparesis 2; 27 patients had progression from onset; 11 progression post-relapse. Total MRI lesions were 2 ( n = 8), 3 ( n = 12), 4 ( n = 12), and 5 ( n = 6). Critical lesions were located on corticospinal tracts, chronically atrophic in 26/38 (68%) and involved cervical spinal cord in 27, cervicomedullary/brainstem region in 6, thoracic spinal cord in 4, and subcortical white matter in 1.
Progressive motor impairment may ascribe to a critically located CNS-demyelinating lesion in patients with highly restricted MRI burden. Motor progression from a specific demyelinating lesion has implications for understanding multiple sclerosis (MS) progression.

Posterior cervical laminectomies and laminoplasties are common treatments for cervical spondylotic myelopathy. However, recent studies demonstrated that positional spinal cord compression occurred after cervical laminectomies and caused postoperative progressive myelopathy. Although there were no such reports after laminoplasties, we report two cases in which symptomatic extraordinary positional spinal cord compression occurred after laminoplasties in this paper.
This study included two patients who showed progressive myelopathy: one case after a laminectomy following failure of a single-door laminoplasty and one case after a double-door laminoplasty without interlaminar spacers.
The MRIs showed mild cord compression in the neutral position in both cases. However, the patients could not extend their necks, because it triggered severe neck pain and numbness. Therefore, the positional CT myelography (CTM) was taken in the flexion and extension positions, and it showed severe spinal cord compression only in the extension position. Posterior instrumented fusions were performed for both patients, which improved their symptoms.
This paper demonstrates that postoperative positional spinal cord compression during neck extension caused a progressive myelopathy even after laminoplasty. When myelopathy symptoms worsen after laminoplasties, we recommend positional CTM/MRI evaluation, even though there is no apparent cord compression in the neutral MRI.
