A 2cm typical cavernous malformation with complete haemosiderin ring and a mulberry internal structure situated at the junction of the posterior temporal, parietal and occipital lobes. It shows a peripheral haemosiderin staining and demonstrates lobulated internal areas of T1 hyper intensity with minor internal areas of enhancement. No evidence of a venous angioma, and no evidence of enlarged adjacent vessels.
There is a small development venous anomaly in the left frontal lobe.
The small focus of signal susceptibility in the left pons is unchanged and consistent with a small cavernoma.
Rest of the brain is unremarkable; aside from afore mentioned lesions, cerebral parenchymal signal intensity and architecture are normal, with no other lesions identifiable. Normal flow voids are identified from the major arteries at the base of the brain. Ventricles and sulci are normal.
CONCLUSION: Typical cavernous malformation of left cerebral hemisphere and left pontine area as described with no evidence of an associated venous angioma or arteriovenous malformation.
