To investigate the association between ultraearly hematoma growth (uHG) and clinical outcome in patients with spontaneous intracerebral hemorrhage (sICH) receiving hematoma evacuation. ⋯ uHG is a helpful predictor of unfavorable outcome in sICH patients treated with hematoma evacuation. The optimal cutoff of uHG to assist in predicting unfavorable outcome in sICH patients receiving hematoma evacuation is 8.7mL/h.

Training of intra-axial brain tumor resection using a self-made simple device with agar and gelatin.
Self-made devices composed of agar and gelatin gel were used for resident training in intra-axial brain tumor resection. The mixture gel of agar and gelatin is retractable and can be suctioned. Hardness of the gel depends on the concentration of the solution. Therefore, by changing the concentration, it is easy to make gels of various hardness. ⋯ Our devices with "tumors" of various hardness appear to be suitable for resident training in each surgical skill. For the next step of this study, we will attempt to fabricate more practical 3-dimensional gel models for presurgical simulation.

Focal cortical dysplasia (FCD) is one important cause of drug-resistant epilepsy potentially curable by epilepsy surgery. We investigated the options of using neuronavigation and intraoperative magnetic-resonance tomographical imaging (MRI) to avoid residual epileptogenic tissue during resection of patients with FCD II to improve seizure outcome. ⋯ Excellent seizure outcome after surgery of patients with FCD II positively correlated with the amount of resection, histologic subtype, and the use of intraoperative MRI, especially when intraoperative second-look surgeries were performed.

Keyhole craniotomy is a type of pterional craniotomy that involves a minimally invasive approach for the treatment of cerebral aneurysms. Currently, the minipterional keyhole craniotomy and supraorbital keyhole craniotomy procedures are frequently performed. ⋯ The success solely depends on careful selection of patients and the experience of the surgical team.

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.
