Case Reports
Concomitant Primary CNS Lymphoma and FSH-Pituitary Adenoma Arising Within the Sella. Entirely Coincidental?
Collision tumors are the simultaneous occurrence of more than one type of neoplasm within an anatomic space. In the pituitary sella, collision tumors are exceedingly rare, and not much is known about their etiology and prognosis. ⋯ Four cases of collision tumors of primary pituitary lymphoma and adenoma have previously been reported. This case represents the first combination of an FSH-adenoma and a DLBCL in the literature. Prompt involvement of the hematology-oncology team contributed to the good outcome seen in this case. The putative role played by pituitary hormones in tumorigenesis is reviewed in this case report. The association is either a chance occurrence or due to the induction of lymphoma cell proliferation by the binding of FSH produced by the adenoma to the FSH receptors on the lymphoma cells.

The scope and purpose of this work is 2-fold: to synthesize the available evidence and to translate it into recommendations. This document provides recommendations only when there is evidence to support them. As such, they do not constitute a complete protocol for clinical use. ⋯ We think it is important to have evidence-based recommendations to clarify what aspects of practice currently can and cannot be supported by evidence, to encourage use of evidence-based treatments that exist, and to encourage creativity in treatment and research in areas where evidence does not exist. The communities of neurosurgery and neuro-intensive care have been early pioneers and supporters of evidence-based medicine and plan to continue in this endeavor. The complete guideline document, which summarizes and evaluates the literature for each topic, and supplemental appendices (A-I) are available online at https://www.braintrauma.org/coma/guidelines.

Multicenter Study Clinical Trial
Long-Term Clinical and Angiographic Outcomes Following Pipeline Embolization Device Treatment of Complex Internal Carotid Artery Aneurysms: Five-Year Results of the Pipeline for Uncoilable or Failed Aneurysms Trial.
Early and mid-term safety and efficacy of aneurysm treatment with the Pipeline Embolization Device (PED) has been well demonstrated in prior studies. ⋯ Our 5-yr findings demonstrate that PED is a safe and effective treatment for large and giant wide-necked aneurysms of the intracranial ICA, with high rates of complete occlusion and low rates of delayed adverse events.

Historical Article
A History of the Council of State Neurosurgical Societies.
As neurological surgery evolved into its own subspecialty early in the 20th century, a need arose to create an environment for communication and education among those surgeons working in this burgeoning surgical discipline. As the socioeconomic climate in health care began to change in the United States, an unforeseen need arose that was outside the scope of the American Association of Neurological Surgeons, Congress of Neurological Surgeons, and Society of Neurological Surgeons. The capacity to understand and address the evolving socioeconomic landscape and to offer a platform for advocacy required a new entity. ⋯ The CSNS provides a forum in which state societies can meet to identify, understand, and advocate for policies on behalf of organized neurosurgery. The purpose of this paper is to detail the history of the formation of the CSNS. By understanding this history and the need for the development of the CSNS, it is hoped that its evolving role as a voice for neurological surgeons in the modern era of health care will be made clear.
