Description

<jats:p> Multiple vascular patterns are presented in tumors of the central nervous system (CNS), including microvascular hyperplasia, branching capillaries, numerous capillaries without definite pattern, hyalinized vessels, and angiomatous area. These vascular patterns play important roles in pathological diagnosis of brain tumors. Because of insufficient recognition of the significance of the various vascular patterns, only a few of them have been applied in pathological diagnosis, leading to missed diagnosis and diagnostic errors. Microvascular hyperplasia can present in multiple brain tumors but display different diagnostic values. Otherwise, varied brain tumors characterized by branching capillaries or vascular pattern mimicking branching capillaries should be given careful consideration. Therefore, a familiarity of these tumors and their vascular pattern is essential for general pathologists. This study reviews the value of various kinds of vascular patterns for pathological diagnosis of brain tumors, constructs a framework for better understanding, and provides a novel perspective for general pathologists. </jats:p>
