Lipomatosis of nerve (LN) is a condition of massive peripheral nerve enlargement due to proliferation of fibrous and adipose tissue within the nerve, the natural history of which is currently unknown. We measured the pattern of growth in individuals with long-term radiologic follow-up. ⋯ Serial MRI reveals progressive enlargement of LN. The rate of growth was more profound in youth, but also occurred in early adulthood.

Neurosurgical simulation training is becoming increasingly popular. Attitudes toward simulation among residents can contribute to the effectiveness of simulation training, but such attitudes remain poorly explored in neurosurgery with no psychometrically proven measure in the literature. The aim of the present study was to evaluate prospectively a newly developed tool for this purpose: the Neurosurgical Evaluation of Attitudes towards simulation Training (NEAT). ⋯ NEAT is the first psychometrically evaluated tool for evaluating attitudes toward simulation in neurosurgery. Further implementation of NEAT is required in wider neurosurgical populations to establish whether specific population groups differ. Use of NEAT in studies of neurosurgical simulation could offer an additional outcome measure to performance metrics, permitting evaluation of the impact of neurosurgical simulation on attitudes toward simulation both between participants and within the same participants over time.

To present a case of a cavernous malformation presenting with a subdural hematoma. ⋯ The clinical course, radiologic, and intraoperative findings suggest that the subdural hemorrhage was caused by extralesional hemorrhage of the cavernous malformation.

To present a case of a traumatic fracture of a polymethyl methacrylate (PMMA) patient-specific implant (PSI) for cranioplasty. ⋯ PMMA PSIs are commonly used for large defects and generally have good outcomes with low rates of revision. The case report described involves a shattered PMMA PSI after a traumatic impact, which resulted in hemiparesis. The question arises if this type of complication can be easily avoided with the addition of titanium onlay to restrict displacement in the event of fracture. This onlay represents a minor change of technique that could prevent migration of fracture fragments.

Neurophobia is a well-described phenomenon among medical students in many countries. Little is reported concerning the perceptions of neurosciences among medical students in China. ⋯ The low, but not the lowest ranking of self-perceived knowledge in neurology by medical students in Wuhan, China, differs from findings reported in other countries. In this exploratory study the investigators hypothesize that the well-described phenomenon of neurophobia may exhibit a less pronounced influence in Wuhan, China.
