Neurosurgeons are faced with the challenge of planning, performing, and learning complex surgical procedures. With improvements in computational power and advances in visual and haptic display technologies, augmented and virtual surgical environments can offer potential benefits for tests in a safe and simulated setting, as well as improve management of real-life procedures. This systematic literature review is conducted in order to investigate the roles of such advanced computing technology in neurosurgery subspecialization of intracranial tumor removal. The study would focus on an in-depth discussion on the role of virtual reality and augmented reality in the management of intracranial tumors: the current status, foreseeable challenges, and future developments.

Review Case Reports
Sudden neurological deterioration due to repeated intratumoral hemorrhage in a patient with a vestibular schwannoma.
Vestibular schwannomas (VS) are the most common tumors involving the cerebellopontine angle (CPA) and the internal auditory canal (IAC). These tumors are usually slow-growing and commonly present with cranial nerve dysfunction such as hearing loss. Repeated intratumoral hemorrhage (ITH) is extremely rare with only four cases previously reported. ⋯ A summary of these cases is presented and the features of ITH are discussed. Patients affected by repeated ITH present with sudden headache and ataxia. Rapid worsening of cranial nerve dysfunction such as hearing loss or facial nerve palsy is suggestive of ITH.

Review Case Reports
Surfer's myelopathy: A rare presentation in a teenage gymnast and review of the literature.
This article describes a novel setting for a rare nontraumatic spinal cord injury referred to as Surfer's myelopathy. The patient is a 16 year-old female cheerleader who presented following a gymnastics practice where she was repeatedly performing back handsprings. She demonstrated progressively worsening midthoracic back pain and evolving paraplegia and hypesthesia of the lower extremities. ⋯ The clinical and radiologic findings for this patient are consistent with previous case reports of Surfer's myelopathy. The authors also provide a summary of the current literature describing Surfer's myelopathy, which to date includes 64 reported cases. The diagnosis of nontraumatic spinal cord injury, referred to as Surfer's myelopathy, in a gymnast highlights the importance of greater physician and patient awareness of this rare condition.

Refractory chronic subdural hematoma (CSDH) is rare but remains a difficulty for neurosurgeons, and no consensus on treatment procedures has been established. To discuss effective surgical procedures for refractory CSDH, we analyzed our surgical procedures and outcomes for refractory CSDH. We defined patients with refractory CSDH as those who presented with two or more recurrences. ⋯ When selecting a surgical procedure, assessing whether the CSDH is organized is crucial. Embolization of the MMA may be considered as one of the optional treatments for refractory CSDH without organized hematoma. On the other hand, for refractory cases of organized CSDH, hematoma evacuation and outer membranectomy with large craniotomy or mini-craniotomy assisted by an endoscope may be suitable, as previous reports have recommended.
