Hemangioma of intracranial structures [228.02], Reason for Study: ^Reason: 3T Scanner, CCM Protocol History: Abnormality noted on prior MRI; CCM vs. AVM, please evaluate and compare with priori images Brain MRIRe-demonstration of right cingulate gyrus anterior aspect signal void just above the level of caudate head. The lesion does not show associated edema, nor high signal intensity on T1 weighted image.On Gad enhanced image, there is prominent vascular structure extending from the lesion to the adjacent cortex.There is another linear enhancing structure on the left frontal lobe middle frontal gyrus. These two white matter linear enhancing structure are likely representing developmental venous anomaly (DVA).And the signal void lesion on the right cingulate gyrus likely represent cavernous malformation. The size and MR characteristics of the lesion do not show any interval change since prior exam.There is prominent enhancement on the right side angular gyrus which could represent prominent vein of Labbe or associated small DVA.There focal signal void on the left frontal lobe medial orbital gyrus (series 1202, image 14/28), however, this lesion was not seen on the original gradient echo images, thus the reconstructed images likely represent volume averaging artifact.  The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.Brain MRA:3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.
1. Right cingulate gyrus cavernous malformation with associated developmental venous anomaly. Another developmental venous anomaly on the left frontal lobe and possible DVA on the right angular gyrus. No change since prior exam.2. Normal brain MRA.
