Cavernoma with bleeding. (a) Axial multiplanar GRE MR image (MPGR; GE
Healthcare, Chalfont St Giles, United Kingdom) (600/20; flip angle, 20°;
bandwidth, 122 Hz/pixel; voxel size, 0.78 × 0.9 × 5.0 mm; FOV, 200
× 200 mm) shows a hematoma (arrowhead) with dark border and edema around it in
the right occipital lobe. (b) Follow-up axial T2*-weighted fast
GRE MR image (T2 FFE; Philips) (665/23; flip angle, 18°; bandwidth, 108.6
Hz/pixel; voxel size, 0.9 × 1.1 × 5.0 mm; FOV, 220 ×
192 mm) shows reduction in the size of the acute hematoma. A residual low-signal-intensity
area (arrowhead) is seen at the site of the hematoma, which was a complication of a
cavernoma. A new small cavernoma (arrow) is seen in the left frontal lobe.
T2*-weighted images depict more cavernomas than T2-weighted fast spin-echo
images.
