Case 6 from the re-operation group. The patient operated on for infratentorial ependymoma developed infratentorial-supratentorial EDH. Re-operation of EDH evacuation through craniotomy were performed, with further formation of contralateral cerebral hematoma after the operation. A: Pre-op. MR of case 6 (saggital, enhanced T1-weighted), showing tumor in the IVth ventricle, with heterogeneous enhancement and clear margin. The patient had concomitant hydrocephalus. The tumor was confirmed as ependymoma by postoperative pathological examination. B: Post-op. CT scan 2 days after the operation, identifying right cerebellar and right occipital EDH. The patient was operated on through posterior central approach. Right occipital epidural hyperintensive signal could be seen. Consecutive images showed the hematoma ranged from infratentorial to supratentorial epidural space. C: CT scan 5 days after the right cerebellar-and-occipital epidural hematoma evacuation, identifying left frontal cerebral hematoma. The hemorrhage drained into lateral ventricles.
