Background: Meningiomas presenting with acute subdural hematomas are extremely rare. To the best of our knowledge, only 45 cases have been reported to date. We report on a case of a meningioma mimicking an acute subdural hematoma as well as a thorough literature review. Case Description: A 67-year-old man with no history of trauma was referred to our hospital with sudden onset of decreased level of consciousness and left hemiplegia. Computed tomography revealed an acute convexity subdural hematoma. Emergency surgery to remove the hematoma was performed. The hematoma was found to exist in the extra-axial space and the attached dura mater and pia mater remained intact. Pathological examination revealed a transitional meningioma, the World Health Organization Grade 1. Detailed medical history taken postoperatively revealed that a convexity meningioma had been diagnosed incidentally at another facility 1 year earlier. Conclusion: Acute subdural hematomas due to meningiomas are rare, and establishing the cause is challenging. Prompt and precise diagnosis of such entities may afford patients a better prognosis.

Abstract Background Spontaneous subdural hematoma rarely presents with a hypervascular or malignant tumor but even less frequently in a benign tumor like meningioma. We encountered a patient with acute subdural hematoma associated with benign meningioma. Here, we report this case along with a review of previous reports, especially focusing on their clinical features and possible bleeding mechanisms. Case presentation A 53-year-old Asian woman presented with severe headache and progressive neurologic deterioration due to cerebral edema. The patient was submitted to open surgery for evacuation of the subdural hematoma and concurrent tumor removal on the ipsilateral parietal convexity. A hypervascular, encapsulated mass was identified during surgery and completely removed including the adjacent dura mater (Simpson grade 0). The tumor was histologically confirmed as an angiomatous meningioma (World Health Organization grade I). Her clinical course was uneventful after surgery. Conclusions Although meningiomas are commonly benign according to their histological traits, they can lead to spontaneous bleeding and cause neurologically unstable condition. Therefore, meningiomas need to be considered as a cause of spontaneous subdural hematoma if radiologically suspicious, which should be reflected by proper management for a positive outcome.

✓ In a consecutive series of 39 cases of acute subdural hematoma (SDH), encountered since computerized tomography diagnosis became available, 61.5% were found to be the result of bleeding from a small cortical artery, 25.6% were of venous origin, 7.7% resulted from cerebral contusions, and 5% were acute bleeds into chronic subdural hematomas. Craniotomy was performed promptly on admission, but there was no difference in survival (overall 51.3%) between patients with arterial and venous bleeds. The only apparent factor affecting survival in this series was the preoperative neurological status: 67% of patients who were decerebrate and had fixed pupils prior to operation died. Of patients with less severe neurological dysfunction, only 20% failed to survive.

Exposure to ionizing radiation is associated with increasing risk of various types of hematological malignancies. The results of major studies on association of leukemias and radiation exposure of large populations in Japan and in Ukraine are analyzed. The patterns of different types of leukemia in 295 Chernobyl clean-up workers diagnosed according to the criteria of up-to-date World Health Organization classification within 10–25 years following Chernobyl catastrophe are summarized. In fact, a broad spectrum of radiation-related hematological malignancies has been revealed both in Life Span Study in Japan and in study of Chernobyl clean-up workers in Ukraine. The importance of the precise diagnosis of tumors of hematopoietic and lymphoid tissues according to up-to-date classifications for elucidating the role of radiation as a causative factor of leukemias is emphasized. Such studies are of high importance since according to the recent findings, radiation-associated excess risks of several types of leukemias seem to persist throughout the follow-up period up to 55 years after the radiation exposure.

Background: There is currently little data on the incidence, clinical outcome and management of traumatic interhemispheric subdural hematomas (IHSDHs). Methods: All patients admitted with an acute subdural hematoma (SDH) over a 5-year period at a Level I trauma center were included. A detailed review of all cases of large IHSDH (≥7 mm) was performed to document clinical presentation, management and outcomes. Results: Of 1182 patients with acute subdural hematomas (SDHs), 420 had IHSDHs (24%), and 50 were large IHSDHs. For patients with large IHSDH, the average age was 76 years (±11) and 44% were female. The average GCS was 12 on presentation (±4), and the average GOSE was 4 (±2). 66% of patients had associated cranial/ intracranial injuries (fracture, subarachnoid/epidural/SDH) and 26% required operations for acute convexity SDH. Three patients required operations for their IHSDH by inter hemispheric approach. By 10 weeks, 82% had a complete resolution of the IHSDHs. Conclusions: IHSDHs are often referred to as rare entities. Our results show they are common. Conservative management is often appropriate to manage even large IHSDHs, as most resolve spontaneously. This study will help document the occurrence of falx syndrome, as well as the management and outcomes of larger IHSDHs.

The most relevant practice-changing presentations at the 2016 Society for Neuro-Oncology (SNO) Annual Scientific Meeting revolved around the topic of the new 2016 World Health Organization (WHO) classification of central nervous system (CNS) tumors. The most notable change in this new classification is the introduction of molecular markers into the morphologic classification of diffuse gliomas (isocitrate dehydrogenase [IDH] mutation, 1p19q codeletion, and H3K27M mutation), ependymomas (RELA fusion), medulloblastomas (WNT- and sonic hedgehog–activated), and other embryonal tumors (C19MC amplification), thus allowing for more precise diagnosis of these entities compared with the use of morphologic features alone. Among the clinical trials presented, only one phase III trial evaluating a device therapy for treatment of newly diagnosed glioblastoma (EF14; tumor-treating fields) met prespecified statistical criteria for success, showing a modest benefit in progression-free survival and overall survival in patients without progression after radiation and concurrent temozolomide. Other topics of interest included the spatial and temporal heterogeneity of primary brain tumors and the prevalence of burnout among neuro-oncologists.

AbstractIntroduction:Foreign field hospitals (FFHs) may provide care for the injured and substitute for destroyed hospitals in the aftermath of sudden-onset disasters.Problem:In the aftermath of sudden-onset disasters, FFHs have been focused on providing emergency trauma care for the initial 48 hours following the sudden-onset disasters, while they tend to be operational much later. In addition, many have remained operational even later. The aim of this study was to assess the timing, activities, and capacities of the FFHs deployed after four recent sudden-onset disasters, and also to assess their adherence to the essential criteria for FFH deployment of the World Health Organization (WHO).Methods:Secondary information on the sudden-onset disasters in Bam, Iran in 2003, Haiti in 2004, Aceh, Indonesia in 2004, and Kashmir, Pakistan in 2005, including the number of FFHs deployed, their date of arrival, country of origin, length of stay, activities, and costs was retrieved by searching the Internet.Additional information was collected on-site in Iran, Indonesia, and Pakistan through direct observation and key informant interviews.Results:Basic information was found for 43 FFHs in the four disasters. The first FFH was operational on Day 3 in Bam and Kashmir, and on Day 8 in Aceh. The first FFHs were all from the militaries of neighboring countries. The daily cost of a bed was estimated to be US$2,000. The bed occupancy rate generally was <50%. None of the 43 FFHs met the first WHO/Pan-American Health Organization (PAHO) essential requirement if the aim is to provide emergency trauma care, while 15% followed the essential requirement if follow-up trauma and medical care is the aim of deployment.Discussion:A striking finding was the lack of detailed information on FFH activities. None of the 43 FFHs arrived early enough to provide emergency medical trauma care. The deployment of FFHs following sudden-onset disasters should be better adapted to the main needs and the context and more oriented toward substituting for pre-existing hospitals, rather than on providing immediate trauma care.

BackgroundCerebellar liponeurocytoma is a rare benign neoplasm of the central nervous system, which arises mainly in adult patients with only 3 cases reported in children. Due to its rarity, the diagnosis and treatment strategies for cerebellar liponeurocytoma remain unclear. The purpose of this study was to explore the epidemiology, clinical features, imaging findings, pathological characteristics, different diagnoses, treatment, and prognosis of cerebellar liponeurocytoma in juveniles.Case DescriptionA 5-year-old boy was admitted to the department of neurosurgery due to a 5-month history of headaches, nausea, vomiting, dizziness, dysphoria, as well as visual blurring associated with the peak of the headache. Magnetic resonance imaging showed a 4.9×5.4×6.2 cm mass located in the fourth ventricle and cerebellar vermis combined with hydrocephalus and periventricular edema. The mass was completely removed, and pathological examination indicated a cerebellar liponeurocytoma of the World Health Organization Grade II classification.ConclusionThe present study was the first to report a cerebellar liponeurocytoma with total tumor resection and adjuvant radiotherapy in a pediatric patient. Total tumor resection and postoperative radiotherapy together with close and long-term follow-up seem to be the optimal treatment strategy for juvenile patients. However, the side-effect of radiation needs to be considered.

Introduction A variety of different acute subdural hematoma patterns of density have been reported in the literature and are commonly seen in clinical practice, including rare hypodense acute subdural hematomas. It is unclear if these acute hypodense collections are entirely hypodense or if on close inspection, they can reveal subtle, tiny hyperdense components. The purpose of this study was to determine if all acute subdural hemtomas contain a hyperdense component, including seemingly entirely hypodense subdural collections. Methods Non-contrast CT scans of 111 patients containing 320 hyperacute or acute subdural collections were analyzed for the presence of a hyperdense component. Hounsfield measurements were recorded. Results All hyperacute and acute subdural hematomas in our study had a hyperdense component. Hyperacute subdural hematomas have a hyperdense component >97.5% of the time (95% confidence), and acute subdural hematomas have a hyperdense component >99% of the time (95% confidence). Conclusion Lack of a hyperdense component in a subdural hematoma makes acute or hyperacute hematoma highly unlikely, and alternative diagnoses should be considered.

The debate persists about the inflammatory or tumoral, benign or malignant nature of the Inflammatory myofibroblastic tumors (TMI). Radioclinically, they can mimic a malignant neoplasm, although they are classified as intermediate by the World Health Organization (WHO). The diagnosis is almost always made by pathological examination. The treatment is poorly codified but the management is usually surgical. The removal of these tumors is a challenge when the mass is developed at the expense of or in the vicinity of noble organs. Several therapies have been tested to overcome the limitations of surgery, the results are variable. These tumors rarely affect the digestive tract. We propose the study of a case of myofibroblastic tumor developed at the expense of the omentum, five months after a cesarean section, in order to try to determine if it is a rare complication of the postpartum or a fortuitous combination.
