Case 5 from the drainage group. The patient operated on for bi-parietal meningioma developed right temporal-parietal EDH. Epidural drainage with the vacuum system was performed. The drainage was removed 1 day later, with no further complications. A: Pre-op. MR of patient 5 (saggital, enhanced T1-weighted), showing tumor of the bi-parietal lobes, with prominent enhancement and adjacent meninges enhancement. The tumor was confirmed as transitional meningioma by postoperative pathological examination. B: Postoperative CT scan identifying right temporal-parietal EDH after tumor resection. The patient was operated on through bi-parietal approach. C: Post-op. CT scan before epidural drainage removal 1 day later. The epidural hyperintensive signal reduced prominently.
