Congenital arterial and venous anomalies of the brain and skull base.
ABSTRACT Congenital cerebral vascular anomalies include a spectrum of conditions that result from perturbation of normal developmental processes. Although some of these conditions are asymptomatic and well compensated by collateral circulation, others can cause significant morbidity or produce a range of complications for affected patients. Knowledge of the underlying developmental etiologies and the associated imaging characteristics helps fully elucidate the morphologic and hemodynamic details of these lesions and determine the necessity for any intervention.

ABSTRACT: This article provides a summary of how to approach the imaging analysis of lesions of the anterior, central, and posterior skull base. The primary focus is tumors and tumor-mimickers, and representative examples are shown to differentiate the features of lesions that can occur in the same location.Otolaryngologic Clinics of North America 12/2012; 45(6):1385-404.
