ABSTRACT
This is a vascular malformation consisting of variablesized intercapillary spaces, sinusoids, and larger cavernous spaces with no normal intervening brain tissue. Cavernous angiomas are prone to internal thrombosis and haemorrhage, and may present clinically with seizures and focal neurological decits. Angiomas are commonly multiple and have an association with Osler-Weber-Rendu syndrome. A proportion are associated with genetic mutation, and are heritable. They are ‘slow-ow’ lesions and therefore not routinely identied at cerebral angiography. MRI is the imaging study of choice.
