Intractable neuropathic pain following spinal cord injury (NP-SCI) reduces a patient's quality of life. Excessive release of ATP into the extracellular space evokes neuroinflammation via purinergic receptor. Neuroinflammation plays an important role in the initiation and maintenance of NP.

Venous malformation of the orbit(VMO), previously called orbital cavernous hemangioma, has been classified as a vascular malformation according to the International Society for the Study of Vascular Anomalies. Among various surgical approaches for VMO, endoscopic endonasal surgery(EES)has recently been developed, especially for those in the inferomedial quadrant of the orbit. Two 67-year-old and 69-year-old women presented with decreased visual acuity and visual field deficit, respectively.

Objectives: We present a case series of spinal cord cavernous malformations (SCCMs) to describe clinical presentation and outcomes of both surgical and conservative management.

Methods: The clinical courses of patients diagnosed with SCCMs at our institution were retrospectively reviewed. Neurologic symptoms were evaluated using the Modified McCormick Scale.

Article Synopsis
  • Careful consideration of nearby anatomical structures is crucial when accessing deep extracranial schwannomas at the craniocervical junction (CCJ).
  • The study reviews three cases where the anterolateral approach was used for surgical access, highlighting the technique's effectiveness in providing a clear surgical field.
  • Postoperative complications included transient vocal cord partial paralysis and dysphagia, which all improved within a month, indicating that while risks exist, the anterolateral approach remains a viable option for tumor resection in this region.

Neurological deficits following coil embolization of anterior circulation aneurysms due to the toxicity of contrast medium are rare. Here, we describe a patient with mild consciousness impairment and left hemiparesis following coil embolization of a large right middle cerebral artery aneurysm without evidence of ischemia or hemorrhage, who recovered completely with conservative treatment. The patient's clinical course and radiological findings led us to conclude that the neurological deficits were due to the toxic effect of contrast medium used during the coil embolization.

We report a case of intraorbital varix. A 16-year-old girl showed sudden left-sided exophthalmos after vomiting. After several episodes of vomiting, she developed complete loss of vision in the left eye, followed by orbital pain, disruption of eye movement, and periorbital swelling.
