Case ReportsSpinal subdural hematoma following intracranial aneurysm surgery: four case reports.
Four patients presented with rare spinal subdural hematoma (SDH) occurring after intracranial aneurysm surgery and manifesting as postoperative back pain. Magnetic resonance imaging performed from 4 to 11 days after the operation showed acute or subacute thoracolumbar SDH. No patient had risk factors for bleeding at this site (e.g., lumbar puncture, coagulation abnormality). ⋯ Computed tomography performed during the postoperative period showed a suspicious tentorial subdural hemorrhage in Case 1 and an interhemispheric subdural hemorrhage in Case 3. All four patients received conservative management and their lumbago improved. We hypothesize that CSF hypotension due to overdrainage of CSF and downward migration of intracranial SDH under the influence of gravity were involved in the formation of spinal SDH.

Case ReportsLymphoplasmacyte-rich meningioma with atypical invasive nature.
A 12-year-old boy presented with a lymphoplasmacyte-rich (LPR) meningioma in the posterior fossa. The tumor was subtotally removed. ⋯ The Ki-67 staining index using MIB-1 monoclonal antibody was relatively high. (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography revealed high uptake in the tumor. These findings indicate the atypical nature of LPR meningioma.
