Qualitative assessment of pre- and postrupture imaging
| Case | Postrupture Imaginga |
|---|---|
| 1 | Large amount of subarachnoid hemorrhage |
| No hematoma, no mass effect; no intra-aneurysmal thrombus; no lobulations | |
| 2 | SAH, large perianeurysmal hematoma (28 × 22 × 35 mm) with mass effect on the aneurysm (slightly flattened contour right side); no intra-aneurysmal thrombus; no lobulations |
| 3 | SAH, no hematoma; no intra-aneurysmal thrombus; 1 new lobulation |
| 4 | SAH, large perianeurysmal hematoma in Sylvian fissure (46 × 33 × 38 mm) with mass effect, anterior displacement of vessels and aneurysm; no intra-aneurysmal thrombus; no lobulations |
| 5 | Large amount of subarachnoid hemorrhage |
| Hematoma (10 × 20 × 10 mm), no mass effect on the aneurysm; no intra-aneurysmal thrombus; no lobulations | |
| 6 | SAH, no hematoma; no intra-aneurysmal thrombus; no lobulation |
| 7 | SAH, no hematoma; no intra-aneurysmal thrombus; 1 new lobulation |
| 8 | Diffusely spread SAH, no hematoma; no intra-aneurysmal thrombus; the 2 initial lobulations were merged into a single large lobulation |
| 9 | SAH, no hematoma; no intra-aneurysmal thrombus; 1 new lobulation |
↵a None of the prerupture imaging showed an intra-aneurysmal thrombus. Only case 8 showed lobulations on the prerupture imaging (2 lobulations).
