Abstract

The cavernous malformations (CMs) are detected with the help of magnetic resonance imaging (MRI) technique. They appear as heterogeneous, reticulated, “popcorn-like” masses consisting of mixed signal intensities that correspond to intralesional hemorrhage at various stages of evolution with a hypointense rim of surrounding hemosiderin-laden parenchyma. An understanding of the natural history of CMs is paramount in surgical decision-making. The advent of modern MRI has enabled studies of the natural history of CMs by providing a more reliable method to image these lesions. The supratentorial superficial, supratentorial deep, basal ganglia, thalamus and pineal region, corpus callosum, cingulate cortex and ventricular system, insular cortex, infratentorial, and cerebellum and cerebellar peduncles are the regions in which CMs occurs. The chapter explains about these regions and how CMs is found in these regions and the surgical techniques used for treating CMs.
