In adults, meningiomas occasionally display aggressive behavior and may occasionally metastasize. By contrast, pediatric meningiomas are rare, and there is limited information regarding their clinical characteristics, treatment and prognosis. We herein report the case of a 3-year-old boy with anaplastic meningioma with a history of local recurrence and late pulmonary metastasis. At diagnosis, a 70-mm mass lesion in was identified in the right frontal lobe, with intratumoral hemorrhage. The tumor was attached to the falx cerebri and was completely resected...

We report a novel case of a World Health Organization grade 3 anaplastic meningioma arising from the olfactory groove in an 83-year-old woman. Molecular and methylation profiling confirm this lesion to be an NF2 subtype, methylation class intermediate type B meningioma. As most meningiomas in this location are indolent SMO subtype lesions, our report suggests that even though rare, aggressive NF2 subtype meningiomas can also occur along the midline anterior skull base.

Even though a relationship between farmer work and the development of brain tumors was suggest by the scientific literature, a small number of italian studies investigate on the impact of this job on the cancer morbidity of farmer population. The informations about this case-control study were obtained from patients recruited in the Neurosurgical Department of the University-Hospital of Pisa, Italy, from 1990 to 2000. One hundred and seventy-four, newly diagnosed cases of brain tumors (glioma and meningiomas, histologically confirmed), were recruited, such as 522 controls (with other non tumoral neurologic diseases: trauma, etc), by matching cases and controls (1:3), for age (± 5 years) and gender...

OBJECT: The Simpson grading system has played an important role in the surgical resections of meningiomas. This study set out to determine if this grading system predicts meningioma recurrence in a modern cohort of patients with tumors of all World Health Organization (WHO) grades. METHODS: Adult patients who underwent primary, non-biopsy resection of a meningioma at a tertiary care institution between 2007 and 2015 were retrospectively reviewed. Stepwise multivariate proportional hazard analyses were used to identify associations with recurrence following resection...

Meningiomas of the clinoid region pose formidable surgical challenge. Pterional craniotomy is the traditional approach, and often associated with high-risk post-surgical morbidities. In the current presentation, we describe an elderly male with a clinoidal meningioma that underwent a minimally invasive supra-orbital craniotomy for tumor resection. Patient presentation, neuroimaging, and surgical techniques (patient position, incision, anatomical consideration, and surgical steps) are described meticulously...

Although extrahepatic metastases from hepatocellular carcinoma (HCC) are present in only 5-15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma...

OBJECTIVES: It is common to observe the persistence of extra-axial collections after craniotomies. Most of these disappear in weeks or months but some remain. The onset of focal symptoms or the growth of these persistent collections months or years after surgery may indicate the presence of a chronic and latent infection by germs of low virulence such as Propionibacterium acnes (P. acnes). METHODS: We present two clinical cases with persistent extra-axial collections, which required surgery years after diagnosis, in which P...

PURPOSE: Stereotactic radiosurgery (SRS) is a common treatment for intracranial meningiomas. SRS is planned on a pre-therapy gadolinium-enhanced T1-weighted MRI scan (Gd-T1w MRI) in which the meningioma contours have been delineated. Post-SRS therapy serial Gd-T1w MRI scans are then acquired for longitudinal treatment evaluation. Accurate tumor volume change quantification is required for treatment efficacy evaluation and for treatment continuation. METHOD: We present a new algorithm for the automatic segmentation and volumetric assessment of meningioma in post-therapy Gd-T1w MRI scans...

BACKGROUND: Intracranial schwannomas not related to cranial nerves are very rare. Young age, no known history of neurofibromatosis, and seizure as initial symptom have been reported to be associated with intraparenchymal schwannoma. CASE DESCRIPTION: We report a case of supratentorial parasagittal schwannoma in the right frontal region presenting with seizure episode in a 70-year-old man. Computed tomography and magnetic resonance imaging showed a right frontal solid, enhancing extra-axial lesion based on anterior and middle third junction of superior sagittal sinus...

Postoperative pseudomeningocele is an uncommon complication of craniospinal surgery. Diagnosis is reached on a postoperative computed tomography and magnetic resonance (MR) imaging. Demonstration of the location and dimension of the dural defect before surgical therapy is a very important. T1- and T2-weighted MR images revealed a significant pseudomeningocele extending from left cervicooccipital region. Magnitude and phase-contrast-MR images showed a cerebrospinal fluid (CSF) flow into pseudomeningocele, but they no revealed dural defect...

Definitive radiotherapy is an important alternative treatment for meningioma patients who are inoperable or refuse surgery. We evaluated the efficacy and toxicity of CyberKnife-based stereotactic radiosurgery (SRS) and hypofractionated stereotactic radiotherapy (hSRT) as first-line treatments for intracranial meningiomas that were diagnosed using magnetic resonance imaging (MRI) and/or computed tomography (CT). Between February 2005 and September 2015, 41 patients with intracranial meningiomas were treated with CyberKnife-based SRS or hSRT...
