    Abstract Purpose: Brain metastases (BMs) are the leading cause of intracranial malignant neoplasms in adults. WHO, Karnofsky performance status (KPS), age, number of BMs, extracerebral progression (ECP), recursive partitioning analysis (RPA), diagnosis-specific graded prognostic assessment (Ds-GPA) are validated prognostic tools to help clinicians decide on treatment. No consensus exists for repeat stereotactic radiotherapy (SRT) for BMs. The aim of this study was to review the changes in patient characteristics treated with repeated SRTs.
    Methods and materials: The data of patients treated between 2010 and 2020 with at least two courses of SRT without previous whole brain radiotherapy (WBRT) were reviewed. Age, WHO, KPS, ECP, type of systemic treatment, number of BMs were recorded. RPA, Ds-GPA and brain metastasis velocity (BMV) were calculated.
    Results: 184 patients were treated for 915 BMs and received two to six SRTs for local or distant brain recurrence. The median number of BMs treated per SRT was 1 (range: 1-6), for a median of 4 BMs treated during all sessions (range: 2-19). WHO, Ds-GPA and RPA were stable between each session of SRT, whereas KPS was significantly better in SRT1 than in the following SRT. The number of BMs was not significantly different between each SRT, but there was a tendency for more BM at SRT1 (p = 0.06). At SRT1, patients had largest BM and undergo more surgery than during the following SRT (p < 0.001). 6.5%, 37.5% and 56% of patients were classified as high, intermediate, and low BMV, respectively, at the last SRT session. There was almost perfect concordance between the BMV-grade calculated at the last SRT session and at SRT2 (r = 0.89; p < 0.001).
    Conclusion: Repeated SRT doesn't lead to a marked alteration in the general condition, KPS was maintained at over 70% for more than 95% of patients during all SRTs. Long survival can be expected, especially in low-grade BMV patients. WBRT shouldn't be aborted, especially for patients developing more than twelve BMs annually.

    Abstract Background: Contrast-enhanced magnetic resonance imaging (MRI) is the imaging modality routinely used to follow up patients who have undergone surgical resection of brain meningiomas. There are growing concerns about the massive use of gadolinium-based contrast agents (GBCA). Our aim was to evaluate the performance of a new imaging protocol, performed without GBCA injection, in the detection of tumoral residue or local recurrence after surgery of parafalcine and convexity meningiomas.
    Materials and methods: Only adult patients with a documented resected parafalcine or convexity meningioma were included. We performed a dedicated MRI protocol that included non-contrast and post-contrast sequences. The presence or absence of residue on the unenhanced sequences was independently recorded by three observers: first blindly, then in comparison with a baseline enhanced MRI examination.
    Results: A total of 51 patients were included. 37 of them featured a tumor residue on the reference enhanced sequence. Overall, an average of 32 of 37 (87%) residues were identified on the unenhanced sequences that were blindly reviewed; and more than 34 of 37 (93%) were identified with the help of the comparative baseline enhanced examination, with a high sensitivity. The missed cases were related to small residues.
    Conclusion: Unenhanced MRI sequences are highly sensitive and specific in identifying a tumor residue or a local recurrence in the post operative follow up of brain meningiomas. Sensitivity is even higher with the help of a comparative baseline enhanced MRI examination, whatever the strength of magnetic field.

    Abstract Introduction: Subarachnoid hemorrhage (SAH) is a serious pathology, associated with 43% mortality and significant disability. In the absence of relevant guidelines, some teams advocate that patients harboring an unruptured intracranial aneurysm (ICA) abstain from all sports activity, as a prophylactic precaution. The aim of the present study was to evaluate the impact of physical activity as a risk factor for SAH, through a review of the literature.
    Method: A systematic literature review was performed for the period 2000 to 2020 in accordance with the PRISMA guidelines. Prospective and retrospective articles reporting more than 50 patients whose physical activity was associated with onset of SAH were included. The main end-point was prevalence of SAH occurring after physical activity. For comparison purposes, the prevalences of other circumstances were calculated to establish a range of frequency.
    Results: Physical activity appeared to be quite rarely associated with onset of SAH, with a prevalence of 3%, compared to 30% at rest, 7.3% in association with defecation and 4.5% in association with sexual activity. Age under 60 years, male gender (M/F ratio 1.38) and smoking (67.1%) were associated with onset of SAH during physical activity.
    Conclusion: Physical activity appears to be a rare trigger factor for SAH. These results are in contrast to the idea that physical activity should, as a precaution, be avoided in patients with unruptured ICA. There is at present no scientific evidence of an association with aneurysmal SAH.

    Abstract Background: Cerebral vasospasm results from arterial vasoconstriction, mainly following aneurysmal subarachnoid hemorrhage, and may cause delayed cerebral ischemia (DCI). DCI rarely occurs after tumor resection. We performed a systematic review of the literature together with a case report of DCI after meningioma resection.
    Literature review: METHODS: A systematic literature review was performed following the PRISMA statement, searching the PubMed, Medline and Cochrane databases using keywords and MESH terms related to "vasospasm/DCI and meningioma resection".
    Results: In the studies retrieved in the literature, 5 cases of DCI after meningioma surgery were identified. The average age of patients was 52 years. The average onset time of DCI was 9.7 days. Clinical presentation was highly variable: hemiparesis (60%), confusion (60%) and/or aphasia (40%). Meningioma location was most frequently sphenoidal (60%). Most patients had vasospasm in multiple cerebral vessels, involving only the anterior circulation. Various management strategies were used: endovascular treatment (33.3%), antiplatelet therapy (50%) and/or nimodipine (40%). In terms of outcome, there were no deaths, but most patients had variable neurological sequelae (80%): aphasia, visual impairment, hemiparesis.
    Conclusion: The systematic literature review and the present case of DCI following resection of an olfactory meningioma suggested that the main etiologic factors causing this rare pathology are: 1) intraoperative subarachnoid hemorrhagic contamination; 2) microvascular manipulation; 3) and possible dysregulation of hypothalamic function.

    Title translation Impact of NGS results on patient outcome with a multiform glioblastoma.
    Abstract Purpose: Although some genetic alterations in glioblastoma (GBM) have been characterized, the prognostic value of these gene mutations is not yet established in patients treated with standard therapy.
    Patients and method: 40 patients with newly diagnosed GBM, treated between July 2017 and December 2019, and who had genomic analysis were analyzed. Next-generation sequencing techniques (NGS) were used with a panel of 26 genes. Patients were grouped according to MGMT status, the presence or absence of at least one mutated gene on the panel, and p53 expression by immunohistochemistry.
    Results: the median follow-up was 11.5 months (1.0-37). For all patients, the median duration of progression-free survival was 8 months (95% CI, 5.3-10.7) and the median overall survival (OS) was 17 months (95% CI, 7.5-26.5). Progression-free and overall survival were significantly different according to MGMT status but not according to NGS and p53 status. Three groups of patients according to different combined status could be distinguished due to significant differences in overall survival.
    Conclusion: we have shown that the presence of MGMT promoter methylation is a good prognostic factor. By grouping the patients according to their MGMT, NGS and p53 status, three groups of patients could be separated according to their overall survival. However, these results must be confirmed on a larger number of patients.

    Abstract Introduction: Superficial siderosis (SS) of the central nervous system (CNS) is a rare disease characterized by deposition of hemosiderin along the leptomeninges, due to chronic or recurrent bleeding into the subarachnoid space. The association of unruptured intracranial aneurysm (IA) and cortical SS is a quite rare occurrence.
    Methods: Systematic literature review to assess possible commonalities and/or differences of previous reported cases was undertaken.
    Case presentation: We report a case of a 40-year-old woman with a history of generalized seizures over the past year. No clinical history suggestive of aneurysm rupture. Magnetic resonance imaging (MRI) revealed two aneurysms of the right middle cerebral artery (MCA) bifurcation, associated with hemosiderin deposition along the right Sylvian fissure and a third one of the left MCA bifurcation. MRI showed a wall enhancing thickening of the larger right MCA aneurysm. The patient underwent surgical clipping of all 3 MCA aneurysms in a staged procedure. Histological examination revealed hemosiderin deposits within the aneurysm wall and surrounding gliosis.
    Conclusion: Our literature review found 24 reported cases of unruptured IA associated to cortical SS. The possible source for leakages could be neo-vessels visible in IA walls. The case reported illustrates an uncommon presentation of recurrent bleeding from an IA as a source of SS. The presence of apparently unruptured IA surrounded by cortical SS on imaging studies is of high relevance as this should be considered as a sign of aneurysm wall instability and should indicate prompt treatment.

    Title translation Choice optimisation of radiation therapy technique for central neurocytomas from literature data.
    Abstract Neurocytomas represent 0,25 to 0,5 of brain tumours. These tumours have neuronal differentiation. It's a young adult disease. The main treatment is neurosurgery. The place of other therapies is still unclear, noticeably with regards to radiotherapy. This review aim is to determine the place and the modalities of radiotherapy in the management of neurocytomas. A literature search using PubMed allowed to select the most relevant studies. Finally, 22 studies were selected according to pre-established criteria to answer the problem. All studies were retrospective studies except one. The analysis conclusion defined radiotherapy as a treatment of choice in selected patients, when surgical resection was incomplete or when tumour was atypical.
