The authors present 344 (230 females, 114 males) surgical cases of intracranial meningioma. A total of 370 interventions (344 primary procedures, 10 reexplorations for neurologic deterioration, 16 operations for recurrence) were made. Mean follow-up was 38 months. The overall evaluation revealed that 306 (88.95%) patients were completely normal or in a better condition than before operation. 18 (5.23%) were in a worse condition after operation and 20 (5.81%) died. Results suggested that complications and mortality were mostly related to localization and large volume; we also still have problems with aggressive and malignant meningiomas.
A case of acute severe neurologic deterioration following a craniotomy performed for a left frontotemporal arachnoid cyst is reported here. Early postoperative cranial computed tomography (CT) showed a large right parietal intracerebral hematoma which was removed immediately, resulting in neurologic improvement. Surgical and histopathologic observations revealed venous angioma as the cause of the hemorrhage which was not detected on the preoperative cranial CT. Six months postoperatively, the patient developed subdural hematoma over the left cerebral hemisphere with no evidence of trauma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
