Describe the clinical features of vascular malformations of the brain.
Identify the Imaging features that help differentiate brain arteriovenous malformations from other vascular brain lesions.
Discuss how the radiology report should be in these cases including MRi,
CT and DSA.
Cerebral vascular malformations (CVM) include all those alterations in the correct development of the cerebral vascular system.
They include diseases that affect arteries,
veins and capillaries.
DSA is the gold standard method used for the diagnosis,
but recent adavances in MRi and CT are a good non-invasive alternatives. The traditional pathologic classification of cerebro vascular malformation (CVMs) is based on the caliber,
and histologic composition of the component...
Imaging findings OR Procedure details
Intraxial Vascular Malformations: A.
CVMswith arteriovenous shunting: 1.
ARTERIOVENOUS MALFORMATION: Brain AVMs,
or (more speciﬁcally) pial AVMs,
are abnormal connections between arteries that would normally supply the brain tissue (pial vessels) and veins that normally drain the brain,
resulting in arteriovenous shunting with an intervening network of vessels within the brain parenchyma and lack of a true capillary bed.The transition between artery and vein can take place via a so-called...
The radiologist must identify,
understand and correctly classify vascular malformations.
It should realize an appropriate report to be useful for the clinician and the patient.
Information imaging tests are essential to determinate the most appropriate therapeutic approach to each case.
