The aim of the study was to investigate the diagnostic potential of interleukin 6 (IL-6) and other soluble biomarkers in serum and cerebrospinal fluid (CSF) for early diagnosis of cerebral vasospasm (cVSSAH) and external ventricular drain-associated ventriculitis (VCSAH) and to separate these conditions from aneurysmal subarachnoid hemorrhage (aSAH) without further complication (SAHw/o/c). ⋯ CSFIL-6 is increased after aSAH in patients with cVSSAH or VCSAH. Patients with a CSFIL-6 level higher than a C-OFF of 3100 pg/mL have an increased likelihood for VCSAH; patients with CSFIL-6 levels between 530 and 3100 pg/mL have an increased posttest probability for cVSSAH.

Percutaneous endoscopic removal of a lumbar epidural angiolipoma via interlaminar approach: a technical report.
Although percutaneous endoscopic technique has been routinely used in the treatment of disk herniation, there are few reports on its application in the management of intraspinal tumors. We present a case report of lumbar epidural angiolipoma that was totally removed by percutaneous endoscopic technique. ⋯ This report supports the application of percutaneous endoscopic technique in the surgical resection of noninfiltrating extradural lumbar angiolipoma.

Assessment of White Matter Transgression During Neuroendoscopic Procedures using DTI Fiber Tracking.
Presurgical planning allows anticipating intraoperative difficulties, increasing efficiency, and reducing risks. Neuroendoscopy is a minimally invasive technique whose related complications have been focused on cortical function and surface vessels injury. However, white matter disruption has been insufficiently acknowledged. ⋯ This method using tractography and oriented models of surgical instruments allows assessing white matter transgression, both qualitatively and quantitatively, for a deep brain trajectory. Thus our method permits surgeons to optimize safety and avoid transgression of eloquent tracts during surgical planning. Nevertheless, more studies are necessary.

Pericallosal artery aneurysms (PAAs) are usually rare (2%-5%), and treatment is challenging for both surgical and endovascular modalities. We performed this analysis to determine the outcome and prognostic factors after subarachnoidal hemorrhage (SAH) caused by ruptured PAAs. ⋯ Poor admission status, cerebral infarction, and smoking seem to be crucial factors for unfavorable outcome after SAH from PAA.

Hypophysitis is a rare disease entity mimicking a pituitary adenoma. Despite crucial disease involving a pituitary gland which is a main component of the hormonal axis, there have been minimal researches regarding the hypophysitis. In this study, we described the constellation of the preoperative findings including clinical, radiologic, and endocrinologic features, as well as postoperative outcomes of the hypophysitis. ⋯ In this study, the preoperative clinical manifestations, radiologic and endocrinologic features of hypophysitis were described comprehensively. In addition, we also revealed the long-term outcomes of hypophysitis in the aspect of visual function and endocrinologic outcomes. Preexisting visual field defects were improved in all patients (3 cases). However, all patients presented endocrinologic deficiency in preoperative biochemistry, among them, the 4 patients (50 %) were unchanged and the 4 patients (50 %) were exacerbated after surgery. In conclusion, the visual outcomes were satisfactory, however, the endocrinologic outcomes were vice versa, because the preoperative endocrinologic deterioration was unchanged or even aggravated after surgery in some cases.
