==Overview==
[[Cavernous angioma]] is usually a [[benign]] course since it is a [[low-flow]] and [[low-pressure]] [[lesion]]. Patients with [[cavernous angioma]] have variable [[signs and symptoms]], with [[seizure]] as the most predominant [[symptom]], followed by [[hemorrhage]] and [[focal neurologic deficit]].


==Complications==
==[[Natural History]]==
The risk of hemorrhage is not well established, but it is estimated to be 0.2-2% per lesion per year. This risk is increased in patients with established prior hemorrhage.
Once patients become [[symptomatic]], 40-50% present with [[seizures]], 20% present with [[focal neurologic deficits]], and 10-25% present with [[intracerebral parenchymal hemorrhage]].<ref name="pmid32524542">{{cite journal| author=Vercelli GG, Cofano F, Santonio FV, Vincitorio F, Zenga F, Garbossa D| title=Natural History, Clinical, and Surgical Management of Cavernous Malformations. | journal=Methods Mol Biol | year= 2020 | volume= 2152 | issue=  | pages= 35-46 | pmid=32524542 | doi=10.1007/978-1-0716-0640-7_3 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=32524542  }} </ref>


==Prognosis==
==[[Complications]]==
The lesions do not usually produce life-threatening hemorrhages because most hemorrhages associated with the lesions are small and of low pressure.  
*The [[risk]] of [[hemorrhage]] is not well established, but it is estimated to be 0.2-2% per [[lesion]] per year.
Cavernous malformations can occur at any age, but they are most likely to become clinically apparent in patients aged 20-40 years.
*This [[risk]] is increased in patients with established prior [[hemorrhage]].
*The clinical consequences of [[hemorrhage]] vary such that [[location]] becomes important.
*Small [[hemorrhages]] in critical locations can have more severe effects, and thus, they are more likely to produce [[symptoms]] (e.g. [[brainstem ]]involvement).
*Progressive [[neurologic deficits]] are more often associated with [[cavernous]] [[malformations]] in the [[infratentorial space]] and with [[lesions]] that demonstrate slow enlargement because of [[rebleeding]] episodes.

Overview

Cavernous angioma is usually a benign course since it is a low-flow and low-pressure lesion. Patients with cavernous angioma have variable signs and symptoms, with seizure as the most predominant symptom, followed by hemorrhage and focal neurologic deficit.

Natural History

Once patients become symptomatic, 40-50% present with seizures, 20% present with focal neurologic deficits, and 10-25% present with intracerebral parenchymal hemorrhage.[1]
