Fig. 6From: Brain stones revisited—between a rock and a hard placeAxial CT in bone windows (a) and 3D reconstruction (b) of a 33-year-old male with temporal lobe epilepsy. The large amorphous calcification seen at the base of the left temporal lobe in this NCECT represents a known case of an embolised AV malformation. Calcifications are known to appear in 25–30 % of cases in close conjuction with serpentine vessels or within adjacent brain parenchymaBack to article page
