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.

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.

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.

Bilateral trigeminal neuralgia is a relatively rare disease. Microvascular decompression (MVD) is a safe and effective treatment for unilateral trigeminal neuralgia; however, its utility in bilateral trigeminal neuralgia is unclear. Here, we report our experience with MVD in 13 cases of primary bilateral trigeminal neuralgia. ⋯ Vascular compression plays a causative role in bilateral and unilateral trigeminal neuralgia. MVD appears to be a safe and effective treatment option in patients who are refractory to pharmacotherapy.

To research the early acute response events of facial nerve injury. ⋯ Nissl body dissolution, typical polygonal shape disappearing, cell swelling, facial neuron mortality and apoptosis, and up-regulated expression of caspase-3, LC3, and Beclin1 are the early events of cell death after facial nerve injury, which are the important precursors to facial nerve injury.
