The following is a report on a rare parenchyma meningioma and the computed tomography (CT) and magnetic resonance imaging (MRI) findings. To our knowledge, this was the first characterization of magnetic resonance spectroscopy (MRS) in a parenchyma meningioma.Three days after initial presentation, a 14-year-old female student reported feeling tingling in her cheek, grading 3 to 4 points. Two hours later, the tingling had disappeared. The patient was admitted to hospital with stable vital signs and no abnormal presentations upon physical examination. A routine CT scan of the brain showed a quasicircular region of the left occipital lobe was homogenous hyperdense and an arcualia calcification was found on the lesion's margin and the boundary was ill-defined. Further MRI and contrast-enhanced scanning of the brain showed that a lobulated nidus with abnormal signaling was present in the left occipital lobe and was approximately 1.9 × 2.0 cm. Hypointensity on T1-weighted imaging and a slight hyperintensity on T2-weighted imaging was also observed. A short T2 signal appeared on the margin and a few longer T2 edema zones appeared around the nidus, whereas the lesion showed homogenous enhancement. MRS was characterized by a slight or moderate increase of a choline (Cho) peak and a small reduction of the N-acetyl aspartate (NAA) peak. After completing the preoperative preparation, the excision of the supratentorial deep lesions was performed on the patient. The pathology led to a diagnosis of a left occipital lobe meningioma, WHO I. The patient was followed-up for 14 months postoperation, and had no reoccurrences.Intraparenchymal meningioma rarely occurs in brain parenchyma, and is characterized by lesions with abundant blood supply and requires a glioma to be identified. MRS is a potential tool for preoperative diagnosis of intraparenchymal meningioma.

“…Our review of the literature revealed fteen well-described cases of complete intraparenchymal meningioma. These mostly affected the cerebral hemispheres of patients aged between 14-month and 66-year-old [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Only one case occurred in the medulla oblongata parenchyma, and was identi ed as meningothelial meningioma in 1985.…”

Background: Glioma is the most common tumor occurring in the brainstem. A primary intraparenchymal meningioma located in the brainstem without dura attachment is rare. Meanwhile, atypical meningiomas that occur in the medulla oblongata parenchyma, and without dura coverage, are extremely rare. In this study, we report the first case of atypical meningioma in the medulla oblongata parenchyma and review the existing literature.Case presentation: A 38-year-old female was admitted at our hospital with a 2-week history of progressive neck and occipital pain. Magnetic resonance imaging revealed a presence of a 1.5x0.9cm mass lesion, located in the left side of the medulla oblongata, which was hypointense on T1-weighted and hyperintense on T2-weighted images, and with inhomogeneous enhancement following gadolinium-diethylenet-riamine pentaacetic acid (Gd-DTPA) administration. The initial preoperative diagnosis was glioma or angioblastoma. The patient underwent a total surgical resection of the left medulla oblongata tumor and the histopathological examination indicated that the lesion was an atypical meningioma. The patient returned to normal life after surgery.Conclusions: Although glioma is the most common tumor occurring in the brainstem parenchyma, the possibility of meningioma cannot be ruled out in this area.

Background: ntraparenchymal meningiomas without dural attachment are extremely rare, especially in female children. To our knowledge, fibrous intraparenchymal meningioma located in the temporal lobe has never been reported in female children. The significance in the differential diagnosis of lesions in the temporal lobe should be emphasized.Case presentation: A 12-year-old girl was admitted to our hospital, complaining of recurrent generalized seizures for 2 months. Magnetic resonance imaging demonstrated a solid lesion located in the temporal lobe. The lesion underwent gross total resection. Histopathological examination indicated that the lesion was a fibrous meningioma. Postoperative rehabilitation was uneventful. Conclusions: This case report presents an extremely unusual intraparenchymal fibrous meningioma of the temporal lobe with peritumoral edema and reviewed 20 intraparenchymal meningioma cases in children and to discuss the clinical presentation and treatment, differential diagnosis, and radiological features.
