Malignant meningiomas are uncommon intracranial tumors. The metastasis of malignant meningiomas to distant extracranial sites are well known. However, dissemination of the tumours in the cerebrospinal fluid (CSF) is rare and few cases have been reported. We present a case of histologically proven malignant meningioma with CSF dissemination at the remote intracranial area and into the spinal canal detected with magnetic resonance imaging.

OBJECTIVE: The apparent increase in the incidence of the intracranial meningiomas in the elderly is due in part to improved diagnostic tools and improved span of life. The authors carried out a retrospective study to validate the use of the Clinical-Radiological Grading System (CRGS) as a clinical tool to orientate surgical decision making in elderly patients and to explore prognostic factors of survival. METHODS: From January 1997 to January 2006, the authors consecutively recruited and surgically treated 20 patients older than 65 years of age with radiologic findings of intracranial meningiomas and a preoperative evaluation based on the CRGS. RESULTS: High CRGS score was associated with a higher probability of good outcome (p=0.004) and a lower probability of postoperative complications (p=0.049). Among the different subset items of the CRGS score, larger maximum tumor diameters (D> or =4cm) and the presence of a severe peritumoral edema were associated with incidence rate of postoperative poor outcome and complications (p<0.05). Additionally, the critical location of the tumor was also correlated with poor outcome (p<0.05). CONCLUSION: A CRGS score higher than 13 is a good prognostic indication of survival. The CRGS score is a useful and practical tool for the selection of elderly patients affected by intracranial meningiomas as surgical candidates.

OBJECTIVE: The authors report the evaluation of the surgical outcomes and postoperative complications for the 39 cases of parasagittal meningioma. METHODS: Thirty-nine patients have undergone operations for parasagittal meningioma between March 1994 and March 2002. The medical records and neuroimaging studies of thirty-nine patients were surveyed retrospectively to find out the perioperative clinical status, radiologic findings, operative methods, and postoperative complications. RESULTS: Preoperative symptoms were motor weakness(12), seizure(11), headache(11) and so on. The parasagittal meningioma was classified into lateral attachment(27), partial occlusion(4) or total occlusion(8) according to the degree of infiltration and into anterior one third(7), middle one third(28) or posterior one third(4) from the viewpoint of the origin site. The degree of tumor removal was classified into Simpson Grade: Grade I(13), Grade II(24), Grade III(2). Suture of the opened sinus was done in seven patients going through an operations. Four patients of them underwent sinus opening for mass removal and the others due to operative injury. Total removal of the sinus segment was carried out in six patients. The draining veins of six patients got injuried, those of four patients and the others respectively were coagulated and sutured. Postoperative complications were motor weakness(11), CSF leakage(9), seizure(1) and hemorrhage(1). CONCLUSION: However, most of the weakness is transient, the preservation of intracranial collateral circulation is important to minimize the motor weakness. The effort for complete tumor removal is required in parasagittal meningioma to take recurrence into account.

A case of non-traumatic "high pressure" cerebrospinal fluid rhinorrhea is reported. There was a huge fibroblastic meningioma in the left parieto-occipital region along with hydrocephalus. Initially a ventriculoperitoneal shunt was done and then 12 days later the tumor mass was removed totally. After the operations the patient became free of leakage and a direct approach for the cerebrospinal fluid rhinorrhea was not needed.
