“…6,10,24,30,36,38) The frequencies of the subtypes of meningioma with cyst is similar to those of all meningiomas. 10,26,28) However, the frequency of atypical meningioma among cystic meningiomas has recently been reported to be higher than that among all meningiomas.…”

A 29-year-old male presented with loss of consciousness and generalized seizure, followed by right hemiparesis and speech disturbance. Computed tomography and magnetic resonance imaging showed a solid, enhanced tumor with a cyst in the left frontal area with surrounding edema and mild mass effect. The cyst wall was also enhanced. The preoperative diagnosis was cystic falx meningioma. The tumor was totally resected, but most of the cyst wall adhered tightly to the surrounding brain and could not be removed. Histological examination revealed atypical meningioma and tumor cells in the cyst wall. The patient received local radiotherapy to the residual cyst wall with a total dose of 50 Gy.

“…Furthermore, cystic meningiomas can also be identified in the cerebellopontine angle, olfactory groove, suprasellar, falx and ventricle, olfactory groove trigeminal nerve or optic nerve (3,5,6,(14)(15)(16)(17)(18)(19). The most frequent histological subtype has been found to be the meningothelial subtype (2,5,20). Notably, atypical meningiomas have the tendency to form a cyst, as opposed to other subtypes of meningioma (17,20).…”

“…Cystic meningioma is a relatively rare condition with incidence rates ranging between 1.7 and 10% worldwide (1)(2)(3)(4)(5). While meningiomas are considered more likely to appear in females, no substantial difference was identified in the incidence rates between the two genders, according to an analysis of 166 cases of cystic meningioma (2).…”

“…The clinical manifestation of cystic meningioma include, but are not limited to: Headache, seizure, dizziness, personality changes and motor disturbance (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Surgical removal of the entire tumor and its cyst remains the predominant treatment for cystic meningioma (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Cystic meningioma may pose a diagnostic dilemma preoperatively, since it is occasionally difficult to differentiate among glioma, hemangioblastoma, craniopharyngioma and metastatic brain tumor (6)(7)(8)(9)(10).…”

Peritumoral cystic meningioma: A report of two cases and review of the literature

Abstract. The present study reported two cases of cystic meningioma. The clinical manifestations, magnetic resonance imaging (MRI) scan and histological aspects of the lesion and the associated cyst were examined. The classification of cystic meningioma was also discussed. The present study focused on the formation, diagnosis and management of the peritumoral cystic meningioma, and aimed to clarify certain contradictions in the literature concerning the formation of the peritumoral cyst meningioma: MRI alone is inadequate to determine the type of cystic meningioma, or to identify neoplastic cells on the cystic wall. In conclusion, surgical removal of the entire cyst is recommended in peritumoral cyst meningioma.

Meningiomas are usually solid tumours. Cystic changes in meningiomas are rare. These cysts may occur extratumoural, peritumoural or intratumoural. Diagnostic difficulties arise in cases of cystic meningiomas. Nine cases of cystic meningiomas were operated on in the past 6 years at the department of neurosurgery University of Alexandra. The mean age of patients was 46.2 years. Male to female ratio was 1/2. Less oedema was observed in extratumoural cysts, and more oedema in intratumoural cysts. The fluid contained was dark brown or dirty yellow in intratumoural cysts (type C), xanthochromic in peritumoural cysts surrounded by tumour tissue (Type B), or clear fluid in extratumoural cysts (Type A). Based on these two observations it is proposed that the cyst fluid and peritumoral oedema may represent variable degrees of degeneration or secretion by tumour cells. Pre-operatively diagnostic criteria are presented.

Cystic meningiomas

Abstract: Cysts associated with meningiomas, although uncommon, are certainly not rare. The peritumoral and the intratumoral cysts form distinct subtypes needing separate consideration. Cystic meningiomas are only rarely malignant.
