Miscellaneous vascular malformations (cavernous malformations, developmental venous anomaly, capillary telangiectasia, sinus pericranii)

Abstract

Vascular malformations involving the brain are uncommon lesions that are seen increasingly more often in clinical practice, primarily because of advances in cross-sectional brain imaging. They are typically divided into two main categories: arteriovenous malformations and vascular malformations without arteriovenous shunting, including cavernous hemangioma, developmental venous anomaly, capillary telangiectasia, and sinus pericranii. This latter group is the topic of interest of this chapter. Although all these lesions are clinically relevant, their natural history and prognosis depend on several factors, including lesion type, location, size, and associated conditions. Understanding the associated imaging findings and potential complications of these lesions assists in determining the appropriate treatment options. In this chapter, we attempt to provide a concise review of the imaging methods used in the clinical diagnosis and treatment of the cerebral malformations listed above.
