AI Article Synopsis
- Subacute necrotizing myelopathy (SNM), also known as Foix-Alajouanine syndrome, is a rare neurological disorder caused by a spinal dural arteriovenous fistula (AVF).
- Diagnosis typically involves imaging that shows unusual spinal cord changes, but ring-enhancement can complicate matters, leading to potential misdiagnosis as a tumor.
- A case study highlights how a patient with SNM had to undergo a biopsy due to the confusion with a spinal cord tumor, illustrating the diagnostic challenges of this condition.
Article Abstract
Subacute necrotizing myelopathy (SNM) or Foix-Alajouanine syndrome is a rare disease characterized by progressive neurological dysfunction caused by a spinal dural arteriovenous fistula (AVF). Radiological diagnosis is usually suspected when there is intramedullary nonspecific enhancement and perimedullary flow voids. Ring-enhancement is rarely reported in the scope of AVF, which poses a diagnostic challenge and raises the suspicion of a spinal cord tumor. In such situations, biopsy can be required and delay proper diagnosis. We report the case of a patient with SNM, who underwent biopsy on the assumption of it being a spinal cord tumor.

Background: Spinal schwannomas presenting with an intraspinal hematoma or subarachnoid hemorrhage are extremely rare, and patients often have severe spinal cord compression symptoms. However, the mechanism underlying the bleeding remains unclear.
Case Presentation: We present the case of a 53-year-old Chinese female diagnosed with a T12 schwannoma accompanied by an intratumoral hematoma.

Background: The best open side for unilateral open-door laminoplasty (UODL) to treat inconsistent cervical ossification of the posterior longitudinal ligament (OPLL) needs to be identified.
Methods: Thirty-one individuals with inconsistent OPLL who underwent UODL between January 2016 and December 2018 were retrospectively divided into two groups: when the side of the open door was consistent with the side of the larger ossification occupancy area, patients were placed in the Consistent group; when the side of the open door was contralateral to the side of the larger ossification occupancy area, patients were placed in the Contralateral group. The following parameters were evaluated: neck disability index (NDI) score, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, postoperative laminoplasty opening width and angle, and spinal cord diameter ratio.

Background: Degenerative cervical myelopathy is one of the most common causes of spinal cord dysfunction. Cervical laminoplasty is an excellent surgical procedure that address the underlying pathology along with motion preservation with various advantages over other surgical options. While the advantages are intuitive and are being proven in multiple recent studies, concerns regarding failure still remains precluding wider utilization despite evidence to the contrary.

Exposure to nature is associated with better mental health in the general population, but prior evidence suggests that people living with severe, chronic mobility impairment from paralysis due to spinal cord injury (SCI) may not experience similar benefits. Since many people living with SCI use wheelchairs and other medical devices for mobility, further exploration of how people living with mobility disability experience greenspace is needed to achieve equity in access to all public places. We assessed experiences with accessing greenspace reported in a sample of people living with chronic SCI and the meanings they ascribe to these experiences for their health and quality of life.
