Serum hyperglycemia and hypophosphatemia have been reported to be common in patients with aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to explore whether admission serum glucose-phosphate ratio was associated with the severity and prognosis of aSAH. ⋯ The study shows that the glucose-phosphate ratio is a potential biomarker that can reflect disease severity and prognosis in aSAH patients.

Spinal epidermoid cysts are very rare tumors, especially in the thoracic spine; they represent 0.8% of all spinal epidermoids. In adult cases, they are often associated with surgical procedures such as lumbar puncture. We report a rare case of spinal epidermoid cyst in the thoracic spine of an elderly patient who had never undergone lumber puncture, thoracic spinal surgery, or trauma. ⋯ Epidermoid cysts must be considered among spinal tumors in elderly patients. Early detection by diffusion-weighted imaging and complete resection may lead to good neurological outcome.

To study the efficacy of lumbar (AL) magnetic resonance imaging (MRI) in patients with suspected lumbar spinal stenosis (LSS), with and without AL compression. Supine MRI is used in the assessment of patients with LSS. However, MRI findings may poorly correlate with neurologic findings because of the morphologic changes of the lumbar spinal canal between upright standing and supine positions. In patients without significant stenosis in routine lumbar MRI, by applying AL, MRI can show significant LSS. ⋯ The use of AL MRI in patients with clinically suspected LSS could reduce the risk of misdiagnosis of stenosis, leading to inappropriate treatment.

Pseudoaneurysms (PAs) of the extracranial vertebral artery (VA) are rare lesions, representing less than 1% of all aneurysms. Although these lesions may resolve spontaneously, they present a high rupture rate, so early preventive treatment is advised. ⋯ The use of flow diverters seems to be a safe and effective therapeutic option for the treatment of PAs of the extracranial VAs.

Extradural benign cysts located in close proximity to the facet joints are called juxtafacetal cysts. Only about 3.5% of such cysts occur in the cervical spine. To our knowledge, there has been no published article on the endoscopic resection of a cervical facet cyst, and this is the first report. ⋯ The findings suggest that ankylosing spondylitis may cause formation of a juxtafacetal cyst at the mobile levels in a relatively less mobile cervical spine. The endoscopic resection of such cysts is a minimally invasive novel procedure that can cure such patients successfully without unwanted fusion surgery.
