“…The exact mechanism of cyst formation in meningiomas is unknown; however, cellular necrosis, ischemia, hemorrhage, and active fluid secretion by the functional tumor cells into the mass are proposed as the underlying mechanism [9][10][11][12][13][14][15]. Intracranial lesions with cystic or solid cystic appearance as high-grade gliomas, metastasis, hemangiopericytoma, hydatid cyst, and arachnoid cysts are essential differential diagnoses leading to incorrect preoperative diagnosis.…”

“…Intracranial lesions with cystic or solid cystic appearance as high-grade gliomas, metastasis, hemangiopericytoma, hydatid cyst, and arachnoid cysts are essential differential diagnoses leading to incorrect preoperative diagnosis. The differentiation may be difficult and challenging in some cases in which other modalities like brain angiography, Diffusion-weighted imaging (DWI), Apparent diffusion coefficient (ADC) images, and MR spectrography could be helpful [3,[9][10][11][12].…”

Introduction: Cystic meningioma is an unusual shape of meningioma, and the imaging manifestations and site of the solid/cystic components of the mass increase our difficulties in making a diagnosis. Case report: We report a case of a 78-year-old right-handed woman who presented with right-sided hemiparesis, urinary incontinency, and Broca aphasia. A large left-sided frontal region cystic extra-axial mass with a suspicious small solid nodule and adjacent bony erosion was detected on non-contrast CT of the brain. Brain Magnetic resonance imaging (MRI) with gadolinium depicted the cystic and solid components exactly. A probable diagnosis of cystic meningioma was made and subsequently confirmed by histological study after surgical resection of the tumor. To confirm the category and subtypes of the tumor, a histopathological examination of the tumor cells should be done. Conclusion: Cystic or solid cystic intracranial lesions have several differential diagnoses making the final diagnosis difficult in some cases. There are four types of cystic meningiomas according to the Nauta classification that was revised by Jung et al. Determination of the type of cystic meningioma is crucial for surgical planning. To confirm the category and subtypes of the tumor, a histopathological examination of the tumor cells should be done. Our case was a type IV cystic meningioma with a small mural enhancing solid nodule but an associated adjacent bony invasion.

“…Contrast enhanced MRI can distinguish cystic walls infiltrated by tumor cells from those formed by gliotic tissue. 4 Cyst formation in meningiomas is thought to be a resultant of ischemic necrosis, cystic degeneration, intratumoral hemorrhage, trapping of CSF, peritumoral edema into cyst, active secretion by tumor cells, or due to glial reaction and transudation. 1 The most common location of cystic meningiomas is in the cerebral convexity, particularly in the frontal and parietal regions.…”

“…This disease is often difficult to distinguish from other intra axial tumors, including necrotic gliomas. Jorge et al 4 reported that the cystic meningioma simulates an arachnoid cyst on computed tomography (CT) scan and magnetic resonance imaging (MRI), while Qiu et al 7 also reported the presentation of lateral ventricular cystic meningioma. However, cystic meningiomas located in the interhemispheric space are particularly rare and may be difficult to distinguish from other brain tumors.…”

Objective: The presentation of cystic meningioma in the inter-hemispheric near the falx cerebri is uncommon. It is difficult to differentiate it from intraaxial tumors, such as gliomas. Therefore, it is likely that it is misdiagnosed as other types of brain tumors. Methods: In this study, we reported a cystic meningioma case in the interhemispheric location, showing an intramural nodule on magnetic resonance imaging scans. Results: Patient underwent surgical treatment and pathological section confirmation revealing meningioma. The patient was a middle-age woman and had been misdiagnosed as suffering from glioma followed by slight hemipharesis on the right extremities. Conclusions: Although this is a rare case, it will be good if we always consider cystic meningioma in inter-hemispheric space when diagnosing this type of cystic lesion if the magnetic resonance imaging (MRI) shows a cystic lesion mimicking glioma image presentation.
