CT and CT angiography in case 1. (A,B) Initial CT scans reveal characteristic findings of ruptured MCA aneurysm with intrasylvian hematoma. Hematoma volume was calculated as 28.8 ml. (C) Post-operative angiography shows the aneurysm is completely occluded and parent artery is unimpeded. (D) Immediate post-operative CT finding the drainage tube was in good position. (E) CT finding Hematoma's almost drained clean on POD 2. CT, computed tomography; MCA, middle cerebral artery; POD, post-operative day.

Hematoma volume was calculated as 28.7 ml using the formula a x b x c/2 (Figures 1A,B). Surgery was performed successfully on the ruptured aneurysm and no complication was observed during the procedure (Figures 1C,D). On the two day after the operation, CT showed that the hematoma had disappeared (Figure 1E).

CT and CT angiography in case 1. (A,B) Initial CT scans reveal characteristic findings of ruptured MCA aneurysm with intrasylvian hematoma. Hematoma volume was calculated as 16.5 ml. (C) Post-operative angiography shows the aneurysm is completely occluded and parent artery is unimpeded. (D) Immediate post-operative CT finding the drainage tube was in good position. (E) CT finding Hematoma's almost drained clean on POD 3. CT, computed tomography; MCA, middle cerebral artery; POD, post-operative day.

MCA aneurysm and large amounts of intrasylvian hematoma (about 16.5 ml; Figures 2A,B). Coil embolization surgery was performed 5 h after admission. Minimally invasive puncture and drainage were performed immediately after the operation. Surgery was performed successfully on the ruptured aneurysm and there was no complication during the procedure (Figures 2C,D). On the third day after the operation, CT showed that the hematoma had almost disappeared (Figure 2E).
