Review Case Reports
Primary Malignant Lymphoma of the Trigeminal Nerve: Case Report and Literature Review.
Primary lymphomas of the cranial nerves are extremely rare except for optic nerve lymphoma, and it is difficult to make a correct diagnosis in the initial stage. Here, we report a case of primary malignant lymphoma of the left trigeminal nerve that presented as trigeminal nerve disorder. ⋯ This is a rare clinical presentation of malignant lymphoma of the trigeminal nerve. It is difficult to establish a correct diagnosis of trigeminal nerve lesions during the initial stages without biopsy. Therefore it is important that a sufficient specimen should be taken for biopsy without hesitation in order to diagnose and treat rapidly. The most suitable operative approach must be selected in trigeminal nerve lesions considering functional preservation, operative difficulty, preference of each surgeon, and quantity of specimen to be removed.

Review Case Reports
Primary Meningeal Melanocytoma in the Left Temporal Lobe Associated with Nevus Ota: a Case Report and Review of the Literature.
Primary melanocytic neoplasms of the central nervous system are rare lesions arising from melanocytes of the leptomeninge that are found at highest density underneath the brain stem and along the upper cervical spinal cord. Thus most reported cases of meningeal melanocytomas are located in the posterior fossa and the spinal cord, and presentation of a supratentorial tumor is rare. ⋯ Presentation of meningeal melanocytoma in the supratentorial compartment is rare, and its combination with nevus Ota has been reported in very few cases. Although this lesion is benign, it might behave aggressively. Complete surgical resection of the lesion is the preferred therapeutic option.

Review Observational Study
Audit of the Functioning of the Elective Neurosurgical Operation Theater in India: A Prospective Study and Review of Literature.
Knowledge about the utilization of the operation theater (OT) is essential to improve its efficiency. This study evaluated the neurosurgical operation theater utilization in a neurosciences teaching hospital. ⋯ This study identified the proportion of time spent on each activity in the neurosurgical OT. This knowledge is likely to facilitate better planning of neurosurgical theater schedule and result in optimal utilization.

Flow diversion technologies have gained popularity as a novel endovascular approach to treating cerebral aneurysms. Thus far, the results of treatment with flow diverters has been excellent, with comparable morbidity and mortality to stent-assisted coiling but higher complete occlusion. Currently, published data exists for four different flow diversion technologies. We review and summarize the most recent results for these technologies and review differences in flow diverter designs.

Common to the types of surgery that are effective for the treatment of trigeminal neuralgia (TN) is reactivation of herpes simplex virus (HSV). It is likely that such HSV reactivation following surgery indicates altered trigeminal ganglion neuron function, which was caused by the surgery. ⋯ It is suggested that HSV reactivation is a surrogate marker of ganglion neuron injury. The correlation between effective types of surgery and evidence that they alter ganglion neuron function suggests that altered trigeminal ganglion neuron function may be the basis of the surgical efficacy.
