Review Case Reports
Usefulness of embolization for iatrogenic dural arteriovenous fistula associated with recurrent chronic subdural hematoma: A case report and literature review.
Refractory chronic subdural hematomas due to iatrogenic dural arteriovenous fistulas (dAVFs) are difficult to treat. We report our experience and propose a guideline on basis of a literature review for the usefulness of embolization of middle meningeal artery (MMA) for the treatment of the same. ⋯ Refractory chronic subdural hematoma with reaccumulation within a short interval should be subjected to digital subtraction angiography of the MMA. Embolization of ipsilateral MMA is safe, effective, and a useful option for the treatment of iatrogenic dAVF and resolution of hematoma.

Review Case Reports
Extremely Delayed Multiple Brain Metastases from Renal Cell Carcinoma: Remission Achieved with Total Surgical Removal.
Late brain metastasis from renal cell carcinoma (RCC), which is generally considered as metastasis occurring more than 10 years after nephrectomy, often occurs as a solitary lesion, and total resection is recommended to achieve remission. ⋯ Total removal of late brain metastasis from RCC, even occurring with multiple lesions, can achieve total remission under specific conditions.

Review Case Reports
Brain Metastasis from Malignant Peripheral Nerve Sheath Tumors.
Metastatic disease is a well-known sequela of malignant peripheral nerve sheath tumors (MPNSTs). Metastic spread to the brain is unusual. ⋯ Brain metastases from MPNSTs are very rare and represent a poor prognosis, with survival after brain metastasis reported to be approximately 10 months. Early and effective initial diagnosis and treatment of MPNSTs likely represent the best opportunity for increased overall survival.

Histologic Evidence for Arteriovenous Malformation-Like Vasculature Occurring within an Intracerebral Schwannoma: A Case Report and Review of the Literature.
The phenomenon of intracerebral schwannoma is exceedingly rare, and its etiology still a matter of debate. No documented cases of intracerebral schwannoma containing vascular elements consistent with those of an arteriovenous malformation (AVM) have been reported. We describe such a case here. ⋯ To our knowledge, this is the first case of an intracerebral schwannoma with AVM-like characteristics to be reported in the literature. We hypothesize that the co-occurrence of this rare pathologic entity is caused by an interrelated etiologic process, with the tumor microenvironment of the schwannoma inciting the development of the vascular malformation.

An overview of the development of neuroendoscopy at the neurosurgery department, Ibn Sina Hospital in Kuwait, is presented with an outline of difficulties and obstacles faced by the field until it reached its current status. The factors and solutions that helped us overcome these problems are also elaborated on. After a modest beginning few years ago, endoscopic skull base procedures, intraventricular neuroendoscopy, and spinal endoscopy are regularly performed in the department. ⋯ Importantly, a multitude of essential facilities should be available to make such a pattern of practice possible. In our experience, this was made possible through continued efforts that have finally paid off and gradually led to a complete shift of the face of neuroendoscopic practice in our department. Our future endeavors aim at further development of neuroendoscopy in the department to create a center of excellence.
