RESUMO
OBJECTIVE: The primary objective of this study was to explore the clinical characteristics of apoplectic intratumoral hemorrhage in gliomas and offer insights for improving the diagnosis and treatment of this disease. METHODS: We analyzed the clinical data of 35 patients with glioma and hemorrhage. There were eight cases of multiple cerebral lobe involvement, and 22 cases involved a single lobe. Twenty-one patients had a preoperative Glasgow Coma Scale (GCS) score of ≥ 9 and had a craniotomy with tumor resection and hematoma evacuation after undergoing preoperative preparation. A total of 14 patients with GCS < 9, including one with thalamic hemorrhage breaking into the ventricles and acute obstructive hydrocephalus, underwent craniotomy for tumor resection after external ventricular drainage (EVD). One patient had combined thrombocytopenia, which was surgically treated after platelet levels were normalized through transfusion. The remaining 12 patients received immediate intervention in the form of craniotomy hematoma evacuation and tumor resection. RESULTS: We performed subtotal resection on three tumors of thalamic origin and two tumors of corpus callosum origin, but we were able to successfully resect all the tumors in other locations that were gross total resection Pathology results showed that 71.43% of cases accounted for WHO-grade 4 tumors. Among the 21 patients with a GCS score of ≥ 9, two died perioperatively. Fourteen patients had a GCS score < 9, of which eight patients died perioperatively. CONCLUSIONS: Patients with a preoperative GCS score ≥ 9 who underwent subemergency surgery and received aggressive treatment showed a reasonable prognosis. We found their long-term outcomes to be correlated with the pathology findings. On the other hand, patients with a preoperative GCS score < 9 required emergency treatment and had a high perioperative mortality rate.

Primary central nervous system lymphomas (PCNSLs) rarely exhibit intratumoral hemorrhage. The differential diagnosis of hemorrhagic neoplasms of the central nervous system (CNS) currently includes metastatic carcinomas, melanomas, choriocarcinomas, oligodendrogliomas, and glioblastomas. Here we present the clinical, radiological, pathological, and molecular genetic features of six cases of PCNSL associated with intratumoral hemorrhage. The median age of patients was 75 years, with male predominance. While conventional PCNSLs were associated with low cerebral blood volume (CBV), perfusion magnetic resonance imaging (MRI) revealed elevated CBV in three cases, consistent with vascular proliferation. All six cases were diagnosed pathologically as having diffuse large B-cell lymphoma (DLBCL) with a non-germinal center B-cell-like (non-GCB) phenotype; marked histiocytic infiltrates and abundant non-neoplastic T-cells were observed in most cases. Expression of vascular endothelial growth factor and CD105 in the lymphoma cells and the small vessels, respectively, suggested angiogenesis within the neoplasms. Neoplastic cells were immunohistochemically negative for programmed cell death ligand 1 (PD-L1), while immune cells in the microenvironment were positive for PD-L1. Mutations in the MYD88 gene (MYD88) (L265P) and the CD79B gene (CD79B) were detected in five and one case, respectively. As therapeutic modalities used for PCNSLs differ from those that target conventional hemorrhagic neoplasms, full tissue diagnoses of all hemorrhagic CNS tumors are clearly warranted.

BACKGROUND: We report a rare case of sudden bilateral vision loss due to third ventricular cavernous angioma with intratumoral hemorrhage. CASE PRESENTATION: A 45-year-old woman presented decreased visual acuity in both eyes. Her best corrected visual acuity was 0.1 in the right eye and 0.15 in the left eye. Goldmann perimetry showed bilateral central scotomas and bitemporal visual field defects. MRI demonstrated a lesion with mixed hypo- and hyperintensity at the optic chiasm, which was thought to be an intratumoral hemorrhage. The patient underwent bifrontal craniotomy. The tumor was exposed via an anterior interhemispheric approach, and histological evaluation of the mass led to a diagnosis of cavernous angioma. Six months after the surgery, her best corrected visual acuity was 0.9 in the right eye and 0.9 in the left, with slight bitemporal visual field defects. CONCLUSION: Third ventricular cavernous angioma is considered in the differential diagnosis of chiasmal syndrome. Contrast-enhanced MRI and FDG-PET might be useful for differential diagnosis of cavernous angioma from other chiasmal tumors including glioblastoma.

Gamma knife radiosurgery (GKRS) is considered an established treatment for vestibular schwannoma (VS) in selected patients. Spontaneous intratumoral hemorrhage in VS after GKRS is very rare. In this report, we present a 63-year-old gentleman who had right-side severe sensorineural hearing loss on MRI showing a right cerebellopontine angle tumor (volume 4.96 cm3) with an internal acoustic meatus extension. He underwent GKRS with the prescription dose of 12 Gy to the 50% isodose line, covering 4.66 cm3 (i.e., 94%) of the tumor. Ten days later, he experienced a symptomatic intra-lesional hemorrhage with a mass effect over the brainstem. When symptoms did not resolve after an initial conservative approach, he underwent surgical decompression of the lesion. Postoperatively, the patient had facial palsy but was free of disabling vertigo and ataxia. At the 6-month follow-up, he was doing well without any other complaints. Although rare, an intralesional bleed can occur after GKRS in VS and should be suspected when new severe symptoms develop immediately after therapy.

OBJECT: Intratumoral hemorrhage (ITH) associated with vestibular schwannomas (VS) is very rare. We retrospectively analyzed VS patients presenting with ITH in our department to further gain a better understanding of this uncommon clinical presentation. METHODS: We treated seven patients who had VS presenting with ITH between January 2012 and June 2017. All the patients had preoperative computed tomography (CT), computed tomography angiography (CTA), and magnetic resonance imaging(MRI) done which aided in the radiological diagnosis as well as postoperative MRI to confirm the resection extent of the VS. Continuous electrophysiological monitoring of cranial nerves was carried out during surgery. RESULTS: Of the seven patients, three were male and four were female. Their ages ranged from 42 to 71 years (average age, 57.4 years). Two patients reported a history of hypertension. Sudden onset or rapid worsening of clinical symptoms occurred in five patients at time of hemorrhage. The mean diameter of the lesions was 4.1 cm (range, 3.0-5.0 cm). No patient had a pretreatment of stereotactic radiosurgery. Gross total resection was achieved in four cases and subtotal resection in three cases. There were no surgery-related neurological deficits but one patient died 18 days after surgery. Follow-up visits were scheduled at 6 months postoperatively and two patients had tumor recurrence and received stereotactic radiosurgery again. CONCLUSIONS: The incidence of ITH in VS is relatively rare and hypertension may highly correlate with ITH in VS. In comparison with peritumoral adhesion caused by chronic inflammation in multicystic VS with microhemorrhage,ITH caused by acute massive hemorrhage will not increase the extent of peritumoral adhesion immediately. The prognosis of surgery for patients with acute hemorrhagic VS may be better than that for microhemorrhage in multicystic VS. Besides, timely microsurgical treatment is also important to relieve symptoms.

PURPOSE: Although hemorrhage within pituitary adenomas frequently exacerbates the symptoms, there are many grades of severity. Moreover, the contributing factors for symptom severity are still controversial. METHODS: This retrospective study included 82 patients who underwent transsphenoidal surgery for pituitary adenomas with intratumoral hemorrhage. The grades of preoperative symptoms were classified into group A, asymptomatic or minor symptoms; group B, moderate symptoms sufficient for complain; and group C, severe symptoms disturbing daily life. RESULTS: The hemorrhage volume within an adenoma was significantly higher in group C (92.6%) than in groups A (48.6%) and B (58.7%). Both headache and diplopia were dominant in group C, occurring in 72.2% and 27.8% of the patients, respectively. In group C, there was no significant difference in frequency between adenoma extensions into the sphenoid sinus (0%) and involvement of the cavernous sinus of Knosp grade 4 (0%), and extensions into the suprasellar region were not common (38.9%). The most distinctive feature was that "no extrasellar extension" was found only in group C (41.2%), and "multidirectional extension" was not detected in this group (0%). Multiple regression analysis revealed that the most powerful determining factors were the high frequencies of intratumoral hemorrhage and lack of extrasellar and multidirectional extensions. CONCLUSION: Rapid volume expansion of a hematoma and lack of extension or unidirectional extension might lead to significant compression of the sellar and surrounding structures. Of note, the integrity of the sellar dura might contribute to the acute onset of symptom manifestations caused by hemorrhage in pituitary adenomas.

OBJECT: Most pediatric patients that present with a posterior fossa tumor have concurrent hydrocephalus. There is significant debate over the best management strategy of hydrocephalus in this situation. The objectives of this paper were to review the pathophysiology model of posterior fossa tumor hydrocephalus, describe the individual risks factors of persistent hydrocephalus, and discuss the current management options. Specifically, the debate over preresection cerebrospinal fluid diversion is discussed. RESULTS: Only 10-40 % demonstrate persistent hydrocephalus after posterior fossa tumor resection. It appears that young age, moderate to severe hydrocephalus, transependymal edema, the presence of cerebral metastases, and tumor pathology (medulloblastoma and ependymoma) on presentation predict postresection or persistent hydrocephalus. The Canadian Preoperative Prediction Rule for Hydrocephalus (CPPRH), a validated prediction model, can be used to stratify patients at point of first contact into high and low risk for persistent hydrocephalus. CONCLUSIONS: A protocol is proposed for managing hydrocephalus that utilizes the CPPRH. Low-risk patients can be monitored conservatively with or without an intraoperative extraventricular drain, while high-risk patients require the use of an intraoperative extraventricular drain, higher postoperative hydrocephalus surveillance, and even consideration for a preoperative endoscopic third ventriculostomy.

Myxopapillary ependymoma (MPE), a benign histological variant of ependymoma, is found most commonly in the cauda equina region. Primary intracranial MPE is very rare, and most cases are a metastatic deposit from a spinal lesion. Primary cerebral MPEs are usually well-defined solid or cystic lesions without hemorrhage. We report the first case of primary cerebral MPE with intratumoral hemorrhage.

Background: Pilocytic astrocytoma (PA) is a benign glial tumor predominately seen in pediatrics and early adolescence with associated overall good outcomes. Very few cases of elderly PA have been reported in the literature, and they are known to display unique anatomic, histologic, and genetic peculiarities distinct from pediatric disease. We report a rare case of vermian PA in an octogenarian with recurrent spontaneous intratumoral hemorrhage as a presenting symptom. Furthermore, a review of the literature on the peculiarities of PA in the elderly will be discussed. Case Description: An 81-year-old woman presented with features suggestive of repeated posterior fossa hemorrhages characterized by headaches, diplopia, and alteration in sensorium occurring about 5 months apart. Brain neuroimaging showed a cerebellar vermian tumor with features suggestive of repeated intratumoral bleeding. She had an initial ventriculoperitoneal shunting for acute hydrocephalus and subsequently had a suboccipital craniotomy and subtotal tumor excision due to morbid adherence to the brainstem. The histologic diagnosis was PA with Ki-67 <1% and negative for isocitrate dehydrogenase-1. There was a slow but progressive clinical improvement, and she has remained symptom-free for 4 years on follow-up. Conclusion: PA in the elderly is a rare disease with distinct histologic and genetic peculiarities. This case review showed one of the oldest cases of cerebellar vermian PA presenting with recurrent spontaneous intratumoral hemorrhage, an extremely rare occurrence in benign glioma. Although complete surgical excision is recommended, partial resection is advocated for morbidly adherent tumors. Overall prognosis is worse in elderly PA.
RESUMO
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.
RESUMO
BACKGROUND: The aim of this study was to examine associations between genomic alterations in brain metastases and common preoperative imaging findings including overt intratumoral hemorrhage, cystic features, and edema. METHODS: A single-center, retrospective study was performed including patients who underwent surgical resection of brain metastasis with available preoperative magnetic resonance imaging (MRI). Next-generation sequencing of more than 500 coding genes was performed on the resected brain metastases. Preoperative MRI was reviewed to identify the presence of intratumoral hemorrhage, cystic features, and edema in the resected brain metastasis. Genomic data were then correlated with the imaging features using univariate and multivariate nominal logistic regression analyses. RESULTS: We included 144 brain metastases from 141 patients in the study cohort. Half (72) of the metastases had an intratumoral hemorrhage, 26 (18%) had cystic features, and 130 (90%) had edema. Mutations in TP53 were associated with a reduced risk of intratumoral hemorrhage (odds ratio [OR] 0.2, 95% confidence interval [CI] 0.07-0.5, P < 0.001). Mutations in RB1 and CCND1 were associated with elevated risk of the metastasis having cystic features (OR 10.3, 95% CI 2.0-52.6, P = 0.005, OR 18.4, 95% CI 2.2-155.3, P = 0.008, respectively). PIK3CA mutations were associated with a reduced risk of peritumoral edema (OR 0.2, 95% CI 0.04-0.8, P = 0.03). CONCLUSIONS: Several genomic alterations in brain metastases are associated with MRI features including hemorrhage, cystic features, and edema. These results provide insight into tumor biology and patients at risk of developing these imaging features.

The incidence of cerebral herniation caused by intratumoral hemorrhage (ITH) in cystic oligodendroglioma (COD) is exceedingly rare. This study presents a case of cerebral herniation subsequent to cystic oligodendroglioma (COD) and sudden intratumoral hemorrhage. Following initial emergency treatment and evaluation, we successfully circumvented the solid component of the tumor and proceeded with cystic puncture and external drainage to prevent the incidence of brain herniation and mitigate the severity of associated symptoms. Based on preoperative examination results, the cystic glioma was successfully resected, and the patient experienced an uneventful recovery. According to the pathological findings, the oligodendroglioma was classified as World Health Organization (WHO) grade III. The treatment efficacy was comparable to cases of the same pathological grade, in which neither intratumoral hemorrhage nor cerebral hernia was observed.
RESUMO
BACKGROUND: Spinal cord tumors present a challenge in diagnosis and treatment due to their varied histopathological characteristics. While Ewing sarcoma is a rare malignant tumor typically originating from skeletal bone, cases of primary intradural extraskeletal Ewing sarcoma are exceptionally rare. The similarity of its presentation to other spinal tumors further complicates its identification and management. CASE PRESENTATION: We report a case of a 58-year-old Palestinian male with intradural extraskeletal lumbar Ewing sarcoma. The patient initially presented with lower back pain and bilateral S1 radiculopathy, with more severe symptoms on the left side. Magnetic resonance imaging revealed a 7 cm oval-shaped mass with homogeneous contrast enhancement, obstructing the spinal canal from L3/L4 to L5/S1 levels. Initially, a myxopapillary ependymoma was suspected, but the patient's sensory and motor functions suddenly deteriorated during hospitalization. Repeat magnetic resonance imaging indicated heterogeneous contrast enhancement, indicating acute intratumoral hemorrhage. Consequently, the patient underwent emergent L3-L5 laminotomy, with successful gross total resection of the tumor. Histopathological and immunohistochemical analyses confirmed the diagnosis of intradural extraskeletal Ewing sarcoma. Adjuvant therapy was administered to minimize the risk of local recurrence or distant metastasis. A systematic review of relevant literature, along with retrospective analysis of medical records, operative reports, radiological studies, and histopathological findings of similar cases, was also conducted. CONCLUSIONS: Intradural extraskeletal Ewing sarcoma is an infrequently encountered condition in adult patients, emphasizing the importance of considering it in the differential diagnosis of spinal tumors. Surgeons must possess a comprehensive understanding of this rare entity to ensure accurate staging and optimal management, particularly in the early stages when prompt intervention may improve prognosis.

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.
RESUMO
INTRODUCTION: Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle is a rare tumor that has been recently characterized. RGNT was included as a new glioneuronal tumor in 2007 by the World Health Organization (WHO) in classification of tumors of the central nervous system. Within this group we found 34 documented cases. We present a new case of RGNT of the fourth ventricle with intratumoral posttraumatic bleeding and review the existing literature of this new entity. CASE REPORT: A 30-year-old patient was admitted after suffering mild traumatic brain injury (TBI) had headache, diplopia and ataxia. Studies of computed tomography and magnetic resonance imaging revealed a tumor at the fourth ventricle with intralesional bleeding and areas of calcification. She was operated performing macroscopically complete tumor resection. Pathologic examination showed a rosette-forming glioneuronal tumor of the fourth ventricle. CONCLUSIONS: The RGNT of the fourth ventricle are rare and affect young adults. The evidence shows that the prognosis is usually favorable but there is the possibility of progression and recurrence. Intratumoral hemorrhage is a very unusual presentation that involves risk to the patient's life. Surgical resection should be careful due to the location of these lesions and their extension into critical areas, all patients regardless of extent of resection achieved require a long-term monitoring of the risk of late relapse.

A 31-year-old woman presented with a headache and nausea. At presentation, her blood pressure was 114/71 mm Hg with left hemiparesis. Computed tomography revealed a large hyperdense mass in the right temporal lobe accompanied by intralesional calcifications and ventricular perforation. Spot signs were not identified, and cerebral angiography did not reveal any abnormal vasculature. The patient underwent emergency craniotomy assuming an intracerebral hemorrhage. Intraoperatively, grayish tumor tissue was found to intermingle with the clots. Microscopic findings of the tumor revealed neoplastic cells possessing perinuclear halo and cell atypia, and diffusely stained with glial fibrillary acidic protein, which were consistent with anaplastic oligodendrogliomas. However, genomic analyses of the tumor showed non-mutant isocitrate dehydrogenase 1 and telomerase reverse transcriptase, in addition to wild-type O6-methylguanine DNA-methyltransferase. These are equivalent to glioblastoma multiforme. Based on the results, we assumed that anaplastic oligodendrogliomas may develop apoplectic intratumoral hemorrhages that mimic intracerebral hemorrhage. Genomic exploration is recommended for such tumors, coupled with careful follow-up, owing to its potentially aggressive nature.
RESUMO
OBJECTIVE: Vestibular schwannomas (VSs) are benign tumors of the cerebellopontine angle that are typically managed with stereotactic radiosurgery (SRS). Intratumoral hemorrhage (ITH) of VSs is a rare occurrence that results in worsening vestibular and new cranial nerve deficits. Few reports have described the management and outcomes of this entity after SRS. To further delineate the incidence and impact of this event, the authors performed a retrospective review of their VS SRS patients at a single center. METHODS: Between 1987 and 2022, 2058 patients with VSs underwent Gamma Knife radiosurgery (GKRS) at the University of Pittsburgh Medical Center. The authors performed a review of the prospectively maintained VS database at their center to identify patients with ITH. The presentation, management, and clinical and imaging outcomes of the patients are reported. RESULTS: A total of 1902 VS patients had sufficient clinical and imaging follow-up data. Five Koos grade III (n = 1) and IV (n = 4) VS patients developed ITH after GKRS, resulting in a cumulative incidence rate of 0.26%. The age at presentation ranged from 62 to 79 years, and 3 patients were male. The time from VS diagnosis to GKRS ranged from 1 to 13 months, and the time from GKRS to ITH ranged from 2 to 130 months. Three patients had bleeding risk factors. One patient required urgent surgical intervention due to the ITH volume, while the other 4 patients were initially observed. Three patients remained stable and required no delayed intervention; 1 patient required delayed resection because of symptom progression and hemorrhagic expansion. Histopathological analysis revealed multiple fragments of S-100-positive cells, hemorrhage, and hemosiderin-laden macrophages. At last follow-up, 4 patients had clinically improved and 1 patient remained stable. CONCLUSIONS: ITH after VS radiosurgery is a rare phenomenon with a cumulative incidence rate of 0.26% in this series. Patient-tailored management in the form of observation or resection is based on patient presentation, acuity, and ITH size.

Schwannomas are one of the most common types of primary intraspinal tumors. We report a rare case of neurological aggravation due to the intratumoral hemorrhage of a cervical schwannoma. A 65-year-old man presented with lower extremity weakness developing gradually. Tumor resection was performed one week after neurological aggravation occurred. After surgery, he recovered dramatically. There are vascular and mechanical hypotheses for the etiology of intratumoral hemorrhage of schwannoma. In the present case, falling and antiplatelet drugs may have caused the intratumoral hemorrhage. Optimal surgical timing remains controversial. Some reports reveal patients recovered well after urgent surgery. However, even if urgent surgery is performed, some have neurological sequelae. Others reveal patients recovered well after elective surgery without any sequelae. Because previous reports reveal the surgical procedure may damage the spinal cord, urgent surgery may not be compulsory and elective surgery may be a better treatment option. Further investigation is needed to clarify the etiology and optimal timing for surgical treatment of intratumoral hemorrhage.
RESUMO
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.
