Abstract

Introduction Cavernous malformations (CMs), also known as cavernous hemangiomas, cavernomas and cavernous angiomas, can be classified as arteriovenous malformations (AVM) without shunt, and represent the most common type of angiographically occult vascular malformations [1–4]. These lesions are not generally detected on angiograms because of very slow flow or spontaneous thrombosis, and include AVM with thrombosed arteries, small venous angiomas and capillary telangiectasia [2, 5]. They can be, however, best evaluated by magnetic resonance imaging (MRI) and demonstrate characteristic features. Cavernous malformation can occur anywhere in the central nervous system, but most frequently in the cerebrum. In this chapter, the imaging findings of cranial and spinal cavernous malformations will be presented, with emphasis on MRI and its various sequences that are particularly sensitive for detection.
