Benign vascular lesions of bone: radiologic and pathologic features

The benign vascular tumors of bone represent a diverse group of tumors that can present with a broad spectrum of clinical signs and symptoms. They can also present a significant diagnostic challenge due to their widely variab le radiographic imaging and histologic features. Some of the tumors manifes t as clearly benign lesions with tissue-specific diagnostic imaging feature s, while others have non-specific imaging features that may simulate malign ant neoplasm. This article will provide a review of the nomenclature and th e characteristic radiographic and pathologic features of the benign vascula r lesions of bone. The information will aid in improving our diagnostic acc uracy and enhance our understanding of the biologic potential of this diver se group of osseous lesions.
