Technique: Multiplanar, multisequence imaging has been obtained through the brain including pre and post contrast sequences and time of flight MRA.
Comparison: Previous external MRI not available for comparison
Findings: On susceptibility weighted imaging six lesions demonstrate prominent signal loss, located in the right ventromedial thalamus, left cuneus, right occipitoparietal sulcus, left cingulate gyrus, left superior frontal gyrus and right postcentral gyrus. These have appearances consistent with cavernous malformations. The left sided cuneus lesion has a surrounding rim of vasogenic oedema suggesting recent haemorrhage.
The remainder of the brain is unremarkable in appearance. MR angiography is unremarkable, with no abnormal vessels are seen in these regions or elsewhere within the brain.
No developmental venous anomaly is identified.
Conclusion: Multiple cavernomas suggest autosomal dominant multiple cavernoma seen. Left occipital lobe cavernoma appears to have recently bled.
