In an era of residency duty-hour restrictions, there has been a recent effort to implement simulation-based training methods in neurosurgery teaching institutions. Several surgical simulators have been developed, ranging from physical models to sophisticated virtual reality systems. To date, there is a paucity of information describing the clinical benefits of existing simulators and the assessment strategies to help implement them into neurosurgical curricula. Here, we present a systematic review of the current models of simulation and discuss the state-of-the-art and future directions for simulation in neurosurgery. ⋯ Advances in imaging and computer technology have led to the development of different simulation models to complement traditional surgical training. Sophisticated virtual reality (VR) simulators with haptic feedback and impressive imaging technology have provided novel options for training in neurosurgery. Breakthrough training simulation using 3D printing technology holds promise for future simulation practice, proving high-fidelity patient-specific models to complement residency surgical learning.

Review Case Reports
Spontaneous rapid resolution of acute subdural hematoma in children.
Spontaneous rapid resolution of acute subdural hematoma developing secondary to trauma has been reported in the literature, yet it is very rare in pediatric population. The aim of the present review is to analyze mechanisms, characteristics, and outcomes of pediatric acute subdural hematoma cases with spontaneous rapid resolution in conjunction with an exemplary case of ours. ⋯ Analysis of 12 pediatric patients revealed a mean and median ages of 6.87 and 3.9 years, respectively (range = 8 months-18 years). Causes for ASH development were fall, traffic accident, struggle, and child abuse. Main clinical presentations were with depressed sensorium, coma, stupor, drowsiness, headache, motor weakness, lethargy, and seizure. Close follow-up with conservative treatment should be mode of approach in pediatric patients with ASH, if neurological and radiological findings are favorable. However, if patients' neurological status deteriorates after admission to hospital, surgery should be conveyed with no further delay.

Review Case Reports
Rasmussen encephalitis with dual pathology in a patient without seizures: case report and literature review.
Rasmussen encephalitis without seizures is rare. We report a case of Rasmussen encephalitis and cortical dysplasia without epilepsy as well as describe the imaging, pathology, and clinical course and review the literature to investigate whether this may represent a rare subset of Rasmussen encephalitis. ⋯ To the best of our knowledge, this is the third case of Rasmussen encephalitis diagnosed by both imaging and histopathology that had no clinical or electroencephalographic evidence of seizures and is the only case of Rasmussen encephalitis with cortical dysplasia without epilepsy.

Posterior fossa syndrome (PFS) is a severe, postoperative complication occurring in about 25 % of pediatric patients undergoing surgery for midline tumors in the posterior fossa. In recent years, MRI-based research elucidated the cause of PFS and shed new light on its putative pathophysiology. This review highlights the major advances arising from research of this topic. ⋯ Anatomical and functional MRI techniques are suitable and valuable tools with which to detect structural changes and pathophysiological processes in the development and evolution of PFS and may be key, integral components of future clinical research endeavors.

Three tumors are commonly encountered in the posterior fossa of children: pilocytic astrocytoma (PA), medulloblastoma (MB), and ependymoma. However, a variety of additional tumors may occasionally be appreciated. Appropriate and successful treatment of these less common cases is predicated upon correct pathologic diagnosis. ⋯ A number of pediatric brain tumors have a tendency to occur in the posterior fossa. While far less common than PA, MB, or ependymoma, the entities highlighted herein appear to have a degree of proclivity for the posterior fossa of children and as such warrant due consideration in the clinicopathologic workup of these cases.
