Cerebral cavernoma with developmental venous anomaly

Case contributed by Dr Sandeep Bhuta

Patient Data

Age: Adult

Figure a: axial FLAIR reveals a lobulated lesion with a low signal rim suggestive of hemosiderin in keeping with a cavernoma. A subtle flow void is seen extending to the cortical surface suggestive of an associated venous anomaly.

Figure b: axial T1 reveals areas of increased signal within the lesion in keeping with methemoglobin suggestive of recent hemorrhage.

Figure c: is an axial SWI image revealing the expected low signal appearance of a cavernoma due to the susceptibility effects of blood products. The venous architecture of DVA is much better visualized than on the other sequences.

Figure d: is a contrast enhanced T1 image revealing the enhancement pattern of the venous anomaly. The carvernoma is less well visualized than on the SWI image
