The experience with Woven EndoBridge (WEB) device is still limited. The aim of this study is to discuss the efficacy of this new device, focusing on any anatomical and procedural factors influencing aneurysm occlusion. ⋯ Endovascular treatment with WEB is a safe treatment for unruptured cerebral aneurysms, also resulting in a good AO rate in aneurysms that would otherwise require complex assisted coiling techniques. However, results are less favorable in cases of very large aneurysmal neck. Nevertheless, further series with larger patient populations and longer follow-up will define the role of WEB in the treatment of aneurysms.

Stereoelectroencephalograpy (SEEG) is a diagnostic method involving 3-dimensional exploration of brain structures using depth electrodes for locating epileptogenic foci in patients with drug-resistant epilepsy. A variety of frame-based, frameless, and robotic stereotactic systems have been designed for the accurate placement of depth electrodes. ⋯ The patient-customized platforms are comparable in terms of safety, accuracy, and simplicity of use to the existing robotic devices for implantation of depth electrodes in patients undergoing SEEG investigations.

To evaluate safety and effectiveness of supraorbital keyhole approach to the sella and anterior skull base via a forehead wrinkle incision. ⋯ The supraorbital keyhole approach via a forehead wrinkle incision was safe and effective. This approach provided a sufficient visual field for lesion resection and satisfactory cosmetic results for patients.

Noniatrogenic pituitary abscess remains a rare clinical entity, and is the indication for surgery in <1% of transsphenoidal approaches. Correct diagnosis of this rare entity is often delayed. Without timely treatment, morbidity and mortality are high. Of the 200 cases reported to date, less than one-half have identified a causative organism. We report the second case of a pituitary abscess caused by Candida species, and also provide an intraoperative video showing the endoscopic management of this pathology. ⋯ With timely management, including a combination of surgical drainage and appropriate antimicrobial therapy, neurologic outcomes are good in most cases of pituitary abscess; however, endocrinopathy often does not improve. Although most reported cases with identified causative organisms speciate bacteria, some cases are of fungal etiology and require different antimicrobial agents. This further underscores the importance of identifying the causative agent.

Although a subdural fluid collection frequently is observed, diagnostic methods that differentiate between the subdural collection caused by external hydrocephalus and that caused by subdural hygroma have not been established. Here, we report a case of external hydrocephalus caused by Gliadel-induced eosinophilic meningitis that has been previously reported in only 1 case and can be diagnosed by time-spatial labeling inversion pulse magnetic resonance imaging (time-SLIP MRI). ⋯ In the present case, time-SLIP MRI was a useful and noninvasive method for diagnosing external hydrocephalus which was caused by eosinophilic meningitis because of Gliadel-induced eosinophilic meningitis.
