Supratentorial Neurenteric Cysts: Systematic Literature Review and Case Report.
Neurenteric cysts (NC) are uncommon congenital lesions with histopathologic properties derived from the gastrointestinal or respiratory tract. They are typically located in the intradural extramedullary compartment but rarely seen in the supratentorial region. The occurrence of supratentorial NCs (S-NC) presents an interesting quandary regarding their embryopathogenesis. ⋯ If surgically resected, the cyst wall specimen should be sent for pathology review, because of the potential risk for malignancy. If conservatively managed, serial imaging is warranted to track for changes that may indicate transformation. The embryopathogenesis of these rare congenital lesions remains incompletely understood, but the most comprehensive theory involves enteric cell migration to the neuroectoderm during embryogenesis.

Surgical techniques to treat tumors of the spine often require extensive tissue dissection and bony removal, predisposing patients to elevated risk for perioperative morbidity and mortality. When indicated, minimally invasive surgical techniques may be preferred as they result in less collateral damage and quicker recovery times. Full endoscopic spine surgery (FES) represents an ultra-minimally invasive approach that further minimizes tissue damage. The advantages to the application of FES to treat spinal tumors remain unclear. ⋯ The utility of FES in spinal oncology is not well understood. Literature results of this technique show promise. Further study is needed to draw definitive conclusions on FES efficacy and safety in spinal oncology.

Although small unruptured aneurysms rarely rupture, many patients with subarachnoid hemorrhage (SAH) have ruptured small, especially very small intracranial aneurysms (VSIAs; <3 mm) in clinical practice. We aimed to clarify the proportion and clinical features of patients with SAH with ruptured VSIAs. ⋯ Small unruptured aneurysms rarely rupture; however, many patients with SAH have ruptured VSIAs in clinical practice. We observed that VSIA rates among ruptured aneurysms were fairly high. Age, posterior circulation location, and preferable outcome may be important clinical characteristics of ruptured VSIAs.

The purpose of this study was to analyze whether the type of preoperative pain affects the improvement in postoperative pain intensity in patients with a lumbar degenerative disease (LDD). ⋯ Although LLIF was useful for relieving all types of preoperative pain in LDD patients, the NRS scores for preoperative pain were higher in the NeP group than those in the NocP group, and the postoperative NRSLBP and NRSLP score was significantly higher in the NeP group. Thus, controlling preoperative NeP may improve therapeutic efficacy.

We sought to analyze the rate of utilization of methods of cerebrospinal fluid diversion over time in a nationally representative cohort of patients admitted with aneurysmal subarachnoid hemorrhage (aSAH). ⋯ Our results show the temporal trends in utilization of temporary and permanent methods of cerebrospinal fluid diversion and catheter cerebral angiography among patients with aSAH in the United States. The underutilization of VPS following EVD and the differences in EVD and VPS utilization depending on race and hospital size deserve further exploration.
