Cavernous Malormation: A Case Study

Cavernous malformations are well-circumscribed collections of dilated, thin-walled vascular channels lined by a simple endothelium, various stages of blood products can be spotted in these lesions. Most lesions are found by incident, and patients are asymptomatic.[@] If hemorrhage occurs, seizure or focal neurological defect may be noted. Reported hemorrhage rates vary widely from 0.25 to 22.9% per year overall. [@]
Image findings in CT are difficult to diagnosis. Most lesions are not easily identified. If a lesion is large enough, it would be a non-enhancing hyperdense lesion.
In MRI, due to hemosiderin deposition, a characteristic appearance described as “popcorn” can be noted in T2WI and T2* image will demonstrates prominent blooming artifact.
