This case illustrates a left cerebellar DVA associated with locoregional atrophy and likely dystrophic calcification. No convincing evidence of associated cavernoma, although a tiny cavernoma cannot necessarily be excluded.
It has been described that local venous congestion may account for the parenchymal abnormalities, such as the ones demonstrated in this case, related to DVAs. Studies have shown that commonly associated abnormalities include 1:
- atrophy (~30%)
- white matter lesions (~30%)
- dystrophic calcifications (~10%)
