Abstract
We herein report a case of acute subdural hematoma caused by hemorrhagic falx meningioma. The patient was a 64-year-old woman with no significant medical history or prior history of trauma. She experienced a sudden onset of headache and weakness in her extremities. Computed tomography (CT) scan and magnetic resonance imaging (MRI) showed a mass lesion with intratumoral hemorrhage or faint calcification along the left side of the fronto-parietal cerebral falx. There was also a linear lesion at the left side of the falx, suggesting acute subdural hematoma. MRI was performed again on the eleventh day. On precontrast T1-weighted images, intratumoral hemorrhage and widespread left subdural hematoma were shown as high intensity. On postcontrast T1-weighted images, the tumor showed heterogeneous enhancement with a dural tail sign on the falx, indicative of a falx meningioma. She underwent surgical resection, and the histological subtype was transitional meningioma. Nine cases of hemorrhagic falx meningioma associated with acute subdural hematoma have been reported. If not limited to the site of occurrence, there have been 59 reported cases overall. In our investigation, the incidence of hemorrhage is higher in the convexity and lower in the skull base. It is higher for fibrous, angiomatous, and metaplastic subtypes and lower for meningothelial subtype. The location and histological subtype might be risk factors for meningioma associated with subdural hematoma. Further accumulation of cases will be necessary to establish the cause of bleeding.

Abstract
Background Hemorrhagic meningiomas are rare. We report a rare case of nontraumatic convexity and interhemispheric acute subdural hematoma (ASDH) caused by a falx meningioma. Case Description An 84-year-old woman with a history of atrial fibrillation and hypertension who was taking warfarin presented to our emergency department with a sudden disorder of consciousness. The patient had no traumatic events associated with her symptoms. Computed tomography (CT) revealed right convexity and interhemispheric ASDH, mass lesions in the left frontal lobes, and brain herniation. Contrast-enhanced CT revealed vascular structures within the mass lesion. CT angiography (CTA) revealed no aneurysm or arteriovenous malformation, and the venous phase revealed occlusion in the anterior portion of the superior sagittal sinus. The patient had her right convexity and interhemispheric ASDH removed endoscopically. A mass lesion located on the falx, which was easily bleeding, soft, and suctionable, was immediately detected. Histopathological examination revealed fibrous meningioma, a benign meningioma of the World Health Organization grade 1. Despite undergoing aggressive treatment, the patient's general condition deteriorated. Conclusion Hemorrhagic meningiomas can easily be missed with plain CT, and the enhancement effect of CTA and tumor shadow on digital subtraction angiography may not be observed during the acute phase. Surgery for nontraumatic ASDH should be performed considering the possibility that a meningioma causes it.

Abstract
Spontaneous intracranial hemorrhage associated with an intracranial meningioma is rare, with a reported incidence of below 2.4% of all meningiomas. Such cases are described with a cause subdural with intratumoral hemorrhage, which is a challenge for patients and healthcare professionals because it can occur spontaneously without other pathological antecedents. We describe the case of a 55-year-old woman with subdural hemorrhage over the frontoparietal region of the right hemisphere associated with a meningioma, generating a mass effect and shifting the third ventricle and lateral ventricle. Therefore, urgent surgical treatment was decided. A tumor lesion was found with apoplexy, soft consistency, and violaceous color with abundant vascularity in the lesion's center, suggesting a probable angiomatous meningioma. The histopathological evaluation confirmed meningothelial hemorrhagic meningioma grade I, according to the World Health Organization grading. This article discusses the causes, risk factors, diagnosis, and surgical treatment for hemorrhage associated with intracranial meningioma.

Abstract
PURPOSE This study aims to increase awareness of the hemorrhagic presentation of intracranial meningiomas in the emergency department and present clues for neuroradiological diagnosis, which is crucial for pertinent management. We described the prevalence of hemorrhage in a large population of meningioma patients, with emphasis on clinical presentation, computed tomography (CT), magnetic resonance (MR), and digital subtraction angiography (DSA) findings. METHODS This retrospective analysis has been performed at two reference institutions between January 2002 and December 2015, and includes 1304 patients with histologically proven newly diagnosed intracranial meningioma. Clinical features and neuroradiological findings of intracranial meningiomas presenting with hemorrhage have been reviewed. RESULTS Twenty-four patients (1.8%, 16 females, 8 males, age range: 29-88 years) were found to have spontaneous hemorrhagic onset of the newly diagnosed meningioma. A sudden onset occurred in 23/24 patients. Sixteen patients showed isolated intralesional hemorrhage, four had subdural hematomas, and the remaining four presented combined intralesional and subarachnoid (n = 2) or intraventricular (n = 2) hemorrhages. In 13 patients, CT showed both the hemorrhage and the meningioma. In the other 11 patients, diagnosis was achieved by emergency or early surgery (n = 5), MRI (n = 5), and DSA (n = 1). CONCLUSIONS The presence of an underlying meningioma has to be considered in the differential diagnosis of spontaneous intracranial hemorrhage, although this is a rare event. CT, MRI, and occasionally DSA were useful to obtain the diagnosis; however, in up to a fifth of patients, this was achieved at surgery.

Acute subdural hematoma associated with disruption of tumor vessels due to rapid growth of falx meningioma: A case report and literature review. Surg Neurol Int 2022; 13:495.

Abstract
Background:
Meningiomas associated with acute subdural hematoma (ASDH) are rare. The rapid growth of meningiomas has been shown to be one of the mechanisms underlying bleeding. We report the first case of ASDH during an imaging follow-up for the rapid growth of a falx meningioma.
Case Description:
A 77-year-old woman was diagnosed with an incidental tumor along the right falx cerebri 3 years before bleeding. The follow-up magnetic resonance imaging (MRI) after 3 years showed that the tumor volume had rapidly increased from 4.31 cm3 to 22.27 cm3. The blood vessels around the tumor were stretched. The patient was scheduled to undergo tumor removal surgery. However, the patient experienced a sudden onset of disturbance of consciousness and was transferred to our hospital. On arrival, her Glasgow Coma Scale (GCS) score was 6 (E1V1M4) and right hemiplegia was observed. The patient had no history of traumatic events. Computed tomography (CT) showed left hemispheric and interhemispheric ASDH. Digital subtraction angiography revealed neither tumor staining nor abnormal vessels. Gross total tumor removal and hematoma evacuation were performed. There were no obvious active intraoperative bleeding points. The pathologic diagnosis was meningioma, the World Health Organization Grade I. Postoperative course revealed a GCS score of 10 (E4V1M5) and she was transferred to a rehabilitation hospital.
Conclusion:
The disruption of tumor vessels due to the rapid growth of meningiomas may be a cause of bleeding. Incidental falx meningiomas with stretched tumor vessels due to rapid growth could indicate the need for early surgery.

Abstract
OBJECTIVE This study aimed to elucidate the clinicoradiologic features of spontaneous hemorrhagic meningiomas (HMs) and examine risk factors associated with meningioma hemorrhage. METHODS We retrospectively reviewed 651 consecutive meningioma patients who underwent surgical resection in our hospital between January 2011 and January 2021. After exclusions, 169 patients were included for analysis. Patients were grouped according to presence of hemorrhage in the meningioma: the HM group (n = 19) and non-HM group (n = 150). Clinicoradiologic patient data were examined and compared using univariate and multivariate analysis. RESULTS HMs accounted for 2.9% of the entire series of meningiomas. HMs were mainly located at the convexity (63.2%). Mean diameter of HMs was 4.8 cm. On computed tomography, most HMs appeared as mixed isodensity and hyperdensity (84.2%). On magnetic resonance imaging, most appeared as mixed isointensity and hyperintensity on T1-weighted imaging and mixed hypointesity and hyperintensity on T2-weighted imaging (52.6%). Seventeen tumors exhibited heterogeneous enhancement, a dural tail, and peritumoral brain edema. Thirteen showed intratumoral cystic change. The misdiagnosis rate was significantly higher in HMs than non-HMs (31.6% vs. 7.3%; P = 0.005). Intratumoral cystic change was the only independent predictor of meningioma hemorrhage in multivariate analysis (odds ratio 4.116; 95% confidence interval 1.138-14.894; P = 0.031). CONCLUSIONS Mixed isodensity/intensity and hyperdensity/intensity on computed tomography/magnetic resonance imaging in conjunction with heterogenous enhancement, a dural tail, and varying degrees of peritumoral brain edema suggest a high possibility of HM. Presence of intratumoral cystic change was an independent risk factor associated with meningioma hemorrhage.

Meningiomas associated with subdural hematomas: A systematic review of clinical features and outcomes. World Neurosurg 2021; 158:e465-e475. [PMID: 34763104 DOI: 10.1016/j.wneu.2021.11.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2021] [Revised: 10/30/2021] [Accepted: 11/01/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Meningiomas associated with subdural hematomas (SDH) are exceedingly rare. As such, the clinical features, optimal medical and surgical management, and outcomes of treatment for these lesions remain unknown. METHODS We performed a systematic review of the Pubmed and SCOPUS databases for case reports and case series on patients with presumptive clinical or definitive diagnoses of meningiomas presenting with a subdural hematoma on CT scan or MRI. Data on demographics, clinical manifestations, surgical management, adjuvant treatment, and outcome on last follow-up were collected. RESULTS A total of 59 cases met the inclusion criteria, including one described in the current study. The mean age of patients was 62 years (range 5 - 85 years), with a slight female predilection (1.3:1). The most common clinical symptom and sign were headache and focal weakness, respectively. All except two cases underwent surgery - either done singly or staged - for evacuation of hematoma and/or excision of tumor. Treatment for meningiomas associated with SDH was associated with a mortality rate of 12% (6/51) at a median follow up of 3 months. Complete neurologic recovery was reported in 71% of patients. CONCLUSION Subdural hematomas are rare presenting manifestations of intracranial meningiomas. Current management is largely surgical for immediate relief of mass effect and oncologic control. Most patients survived with complete neurologic recovery.

Abstract
OBJECTIVE To evaluate the clinicoradiologic characteristics of hemorrhagic meningiomas (HMs) that are missed or misdiagnosed on radiologic imaging studies. METHODS Clinical and radiologic data from 6 patients with HM who were initially misdiagnosed were collected and recorded respectively. In addition, we performed a literature review for misdiagnosed HM and summarized the results. RESULTS Five of the 6 patients with misdiagnosed HM were female, and 1 was male. Both computed tomography (CT) and magnetic resonance imaging were performed in 4 patients, and CT alone was performed in 2. On CT, the HM was heterogeneously hyperdense in 5 patients and isodense in 1 patient. In all 4 patients who underwent magnetic resonance imaging, the HM was mixed iso- and hypointense on T1-weighted imaging and heterogeneously hyperintense on T2-weighted imaging. Marked heterogeneous contrast enhancement was observed in 2 patients, strong rim enhancement in 1, and peripheral enhancement in 1. The dural tail sign was seen in only 1 patient. The initial radiologic misdiagnoses were subdural hematoma (n = 1), malignant glioma (n = 1), ruptured arterial aneurysm (n = 1), metastasis (n = 2), and uncertain (n = 1). In the literature review, 22 cases of HM diagnostic error were collected. The main misdiagnoses were subdural hematoma (27.3%), traumatic hematoma (13.6%), vascular anomaly (13.6%), malignant glioma (4.5%), and metastasis (4.5%). CONCLUSIONS Our study showed that in patients with HM with inadequate imaging evaluation, a small tumor associated with massive hematoma and atypical imaging features was more likely to be misdiagnosed.

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.

Abstract
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.
