To report the use of the endoscopic transnasal transclival approach to treat tumors involving the clivus region. ⋯ Endoscopic transnasal surgery is an alternative approach to treatment of clivus lesions, and, in expert hands, this technique can obtain good results. Lateral extension and previous treatment were factors that could make the surgery more difficult. Intradural extension did not limit the radicality of the removal.

Intracranial aneurysms are a public health issue with a potential for rupturing, causing significant morbidity/mortality. The prevalence of unruptured intracranial aneurysms, including those that are asymptomatic, varies widely, as it has been determined through autopsy studies as well as conventional angiography. However, computed tomography angiography, a less invasive procedure, has replaced the use of conventional angiography in the recent decades. The objective of the present study is to determine the prevalence of incidental aneurysms. ⋯ The numbers of asymptomatic incidental aneurysms have increased.

In an era of emphasis on disease prevention and its early detection, some have raised the possibility of systematic screening programs concerning brain/cranial disease, namely in search of asymptomatic brain tumors. In this work, the authors enumerate major arguments in favor and against this approach by analyzing the existing literature and conclude there is an absence of evidence sustaining this procedure in terms of clinical and economical advantages, with no clear benefit both to the patient and health systems.
