Fig 3. Patient with a small temporal AVM.
A and B, Frontal projections of internal carotid angiogram done before and after an uneventful embolization. One of 2 draining veins is patent after the treatment.
C and D, Illustrate the cast of glue on unsubtracted DSA and on coronal MR (2D FLASH, performed 26 hours after treatment). The susceptibility artifacts caused by the glue are well illustrated but an associated hematoma could not be definitely defined.
E–G, Axial MR (T2-weighted, DWI b 1000, and ADC maps) performed after treatment show a vasogenic edema in the surroundings of the AVM nidus (arrowhead).
H, Axial CT, performed 2 days later in conjunction with sudden onset of minor symptoms, shows a small hematoma in the area of previous edema. The AVM showed a complete and spontaneous occlusion at follow-up.
