A Rare Triploid Involving the Coexistence of Glioblastoma Multiforme, Arteriovenous Malformation and Intracranial Aneurysm: Illustrative Case and Literature Review. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020331.

Abstract
The coexistence of glioblastoma multiforme (GBM) and arteriovenous malformation (AVM) is rarely reported in the literature. According to the present literature, these GBM or glioma-related vascular malformations may present simultaneously in distinct regions of the brain or occur in the same area but at different times. So far, these distinct hypervascular glioblastomas have been described but are not classified as a separate pathological entities. Considering their heterogeneity and complexity, all the above mentioned cases remain challenging in diagnosis and therapeutic modality. Likewise, there is a paucity of data surrounding the simultaneous presentation of GBM with intracranial aneurysms. In the literature, the independent concurrence of these three intracranial lesions has never been reported. In this article, we present a case who suffered from intermittent headaches and dizziness initially and further radiographic examination revealed an internal carotid artery (ICA) aneurysm that occurred in the patient with coexisting GBM and AVM. Surgical intervention for tumor and AVM removal was performed smoothly. This patient underwent endovascular coiling for the ICA aneurysm 4 months postoperatively. In addition, we also review the current literature relating to this rare combination of medical conditions.

Abstract
Schwannomas are common peripheral nerve sheath tumors. Cavernous hemangiomas are vascular tumors that can affect any organ system. The coexistence of cavernous hemangioma with peripheral nervous system neoplasms is a rare occurrence. So far, 37 cases have been documented, and they have been divided into two categories: conjoined association (neoplasms discovered within the tumor tissue) and discrete association (neoplasms discovered outside the tumor tissue, thus placing neoplasms and tumors in close proximity but in different locations). Schwannomas and neurofibromas are the most prevalent tumors linked to cavernous hemangiomas that have been documented. The author provides a comprehensive review of all such cases published in the past with an emphasis on the implications of their tumorigenetic molecular pathways and syndromic manifestations.

Abstract
BACKGROUND Glioblastoma multiforme (GBM) is the most frequent malignant neoplasm in the adult brain. In contrast, arteriovenous malformations (AVMs) are presumably congenital lesions, usually presenting with hemorrhage. Hypervascular low-grade gliomas associated with AVMs were previously called "angioglioma." An association of AVMs and GBM was also described. STUDY AIMS We discuss the data of the largest series of locally coincident GBM with AVM in a single institution so far. All analyses were explorative only. PATIENTS We report a series of four patients presenting at our department from 2006 to 2014. All patients underwent surgery. The cases were analyzed regarding initial presentation, clinical findings, tumor localization, and histopathologic results. CONCLUSIONS A local coincidence of cerebral AVM and GBM is rare. Only a few reports can be found in the literature. The radiologic as well as the clinical presentations are individual. Proangiogenic factors are discussed as involved in the appearance of both entities in the same location. However, the presence of pathologic vessels within malignant gliomas is well known to all neurosurgeons and proangiogenic activity has been proven. Therefore, it seems possible that tumor activity itself contributes to the pathogenesis of a vascular malformation.

Abstract
Although microvascular proliferation can be observed in glioblastoma, obvious vascularity coupled with coexisting cerebral arteriovenous malformation (AVM) is extremely rare. This report is of a rare case of glioblastoma, coexisting with a cerebral AVM. A 20-year-old male presented with progressive right hemiparesis within 1 month. Cranial magnetic resonance imaging revealed a large bleeding tumor with surrounding dilated vessels. Cerebral angiography demonstrated a left frontal AVM with a 1.2 cm nidus. The patient underwent preoperative embolization and radical resection. The coincidence of glioma and AVM was a rare association. However, the concept of hypervascular glioblastoma has been used in different states from different literature reviews; therefore, the role of proangiogenic factors should be addressed

Abstract
BACKGROUND Rapid growth in cerebral cavernous malformation is rare. A review of the literature revealed 4 patients with known cerebral cavernous malformations who later developed a high-grade glioma at the same site. All 4 patients were females, ranging in age from 25 to 71 years, with imaging confirming rapid growth in the lesion. CASE DESCRIPTION We present the case of a 71-year-old patient with known multiple cavernomas over many years in whom one lesion showed rapid expansion in size. Histological examination revealed the coexistence of a glioblastoma within the cavernoma. CONCLUSIONS We conclude that, although rare, rapid expansion of an existing cavernoma should be considered suspicious for the development of other malignant tumors, and propose adding chronic inflammation in the surrounding brain caused by microbleeds and hemosiderin deposition from the cavernoma to the list of possible causes.

A diagnostic and therapeutic challenge: A case report. Surg Neurol Int 2016; 7:S883-S888.

Abstract
Background: Simultaneous presentation of arteriovenous malformation (AVM) and glioblastoma multiforme (GBM) is rarely reported in the literature and needs to be differentiated from “angioglioma”, a highly vascular glioma and other differential diagnosis such as hypervascular glioblastoma. Incorporating critical features of both, malignant glioma and AVM, such lesions lack a standard algorithm for diagnosis and therapy due to their rare incidence as well as their complex radiological and highly individualized clinical presentation. Case Description: We present a case of a 71-year-old female with newly developing motor deficits and radiographic findings of a heterogeneously contrast enhancing right-sided thalamic lesion with highly prominent vasculature. While computed tomography angiogram and cerebral digital subtraction angiography supported the diagnosis of AVM, contrast-enhancing magnetic resonance imaging (MRI) and MR-spectroscopy was suggestive of malignant glioma. A stereotactic biopsy revealed the diagnosis of a GBM (WHO IV) and the patient was treated accordingly. Conclusion: The coincidental presentation of vascular lesions such as AVM and malignant glioma is rare and presents a major challenge when establishing a diagnosis. The respective treatment decision is complicated by the fact that available treatment modalities (e.g. radiosurgery and/or open resection) carry disease specific complications for each entity. Finding a suitable solution for such cases requires standardization of early diagnostic and therapeutic management.

Abstract
BACKGROUND Angiogliomas are rare low-grade glial tumors with significant vascular components. These tumors are usually seen in the brain, and spinal cord angiogliomas have not been reported in the literature until now. CASE DESCRIPTION We report the case of a 15-year-old boy with an angioglioma of the medulla and cervicodorsal spine, which was completely excised through a combined suboccipital craniotomy and cervicodorsal laminotomy. The patient experienced excellent clinical recovery after the surgery, and follow-up contrast magnetic resonance imaging showed complete excision of the tumor. CONCLUSION The fact that increased vascularity in a glioma does not always indicate a higher grade is confirmed by the unique histology of angiogliomas. These tumors can present with intratumoral bleeding. Awareness of these entities is extremely important. Complete excision can be attempted, and the postoperative prognosis is very good.

Abstract
OBJECTIVES Very few cases of arteriovenous malformations (AVMs) associated with gliomas were reported so far in the literature. METHODS Here, we report a rare case of a glioblastoma with an AVM-like lesion and review the existing literature. RESULTS We report an unusual case of a 72-year old woman, who presented with a progressive history of aphasia, memory deficit, and headache. Initial MRI imaging was suggestive of a high-grade glioma for which a pterional craniotomy was performed. Intraoperatively, the lesion resembled a vascular malformation. Total extirpation of the lesion was verified by intraoperative MR imaging. Initial histopathological analysis revealed an AVM. Due to the discrepancy between the radiologic and histopathologic findings, the patient was monitored at close intervals. Two month later, multiple lesions were visible on MRI imaging, thus, supporting the diagnosis of malignant glioma. Therefore, after reinvestigating the histopathological sections and cutting the paraffin block in additional serial sections, in only 5% of the section a glioblastoma was discerned which was surrounded by an AVM-like lesion. CONCLUSION Gliomas are rarely found in association with AVMs and require accurate diagnostic evaluation and interpretation for adequate therapeutic interventions.

Abstract
The association between vascular malformations and cerebral gliomas is unusual. While the association between cavernous angioma with gliomatous lesions is even more rare, it is considered by certain authors to be a particular pathological entity termed angioglioma. The authors report on two cases of association of a cavernous angioma with a ganglioglioma and an oligodendroglioma respectively. Subsequent review of the literature on the so-called angiogliomas was conducted. In the author's opinion, the entity of angiogliomas represents a general spectrum of angiomatous neoplasms that include gliomatous tumors, in the majority low-grade gliomas, associated with a major vascular component.

Abstract
Cerebral cavernous malformations (CCM) are known to occur in both sporadic and familial forms. To date, there has been no identified association of CCM with glioblastoma multiforme. We present a 69-year-old woman with a 14 year history of multiple CCM who developed progressive aphasia. She had no radiation exposure and had only undergone a single computed tomography scan in her entire life. MRI demonstrated irregular gadolinium enhancement in the area of a prior stable CCM, suspicious for a high grade tumor. Stereotactic biopsy revealed a glioblastoma multiforme. This is a unique case of glioblastoma multiforme arising from the "site" of a known CCM. We review the literature on the genetics of cavernous malformations and propose a mechanism for the tumorigenic potential of these vascular malformations.

Abstract
The finding of cavernous malformations within tumors of the central or peripheral nervous system is a rare occurrence. We report a case of a histologically proven cavernous malformation found within an eighth cranial nerve schwannoma in a 76-year-old man. The patient presented with progressive loss of hearing on the left, facial pain and dysesthesia. Symptoms improved significantly after the tumor was subtotally resected through a left retrosigmoid craniotomy. Including the present report, 34 cases of cavernous malformations associated with tumors of nervous system origin, 24 cases (71%) involving tumors of Schwann cell origin, and 9 cases (26%) involving gliomas have been published. The cases were classified into two forms based on the type of association. Conjoined association, in which the cavernous malformation is located within the tissue of the nervous system tumor, and discrete association, in which the cavernous malformation and nervous system tumor are in separate locations. We explore the etiology of this association and hypothesize that a common genetic pathway may be involved in a majority of these cases.

Abstract
We reviewed the clinical presentation, imaging and histopathologic findings in 4 patients with the diagnosis of arteriovenous malformation associated with glioma that were operated on from 1991 to 2000 in our institution. Four patients (2 males; age between 15 and 52 years) presented with progressive headache with clinical evidence of intracranial hypertension (in 3) and partial seizures (in 1). CT scan showed a brain tumor without any detectable pathologic vessels. Histologic examination revealed astrocytic tumors associated with arteriovenous malformation. No patient presented the vascular component intermixed with the tumor. The arteriovenous-glioma association is rare and must be identified by a clear demarcation between the malformation and the tumor.

Abstract
We report a case of a large cystic astrocytoma associated with arteriovenous malformation in the right cerebral hemisphere of a 16-year-old boy. Neuroimaging showed large abnormal vessels with flow voids and arteriovenous shunt around the cystic lesion. Histologically, the cyst wall was formed by abnormal vasculature and clusters of glial cells forming a papillary growth pattern. The abnormal vasculature consisted of dilated vein-like vessels and medium-sized arteries with incomplete media, and was diagnosed as an arteriovenous malformation. Immunohistochemically, glial fibrillary acidic protein (GFAP) decorated both the perikaryon and the processes of the glial tumor cells. They were negative for epithelial membrane antigen (EMA), cytokeratin, and S-100 protein. Ultrastructurally, the tumor cells were rich in intermediate filaments, and neither cilia, microvilli, nor ependymal rosettes were verified. Based on these morphological features and the low MIB-1 labeling index of 0.8%, the glial tumor was diagnosed as astrocytoma, Grade II, according to the World Health Organization (WHO) tumor classification. An association of glioma with various types of vascular anomalies has been designated as angioglioma. A unique feature of the present case, however, is a papillary growth pattern, which is not listed in the current WHO classification of brain tumors. The recognition of the occurrence of such cases would be important in differential diagnosis of papillary ependymoma and choroid plexus papilloma.

Abstract
Angiomas cavernosos ou hemangiomas ou ainda cavernomas são malformações do sistema nervoso central, classificadas como lesões cerebrais vasculares ocultas, frequentemente assintomáticas, sendo relativamente raras. Definidas histologicamente como massas compactas cavernosas ou canais sinusoidais de vários tamanhos, com paredes finas no interior do parênquima cerebral e sem intervenção do tecido glial. Podem ocorrer em qualquer faixa etária inclusive em neonatos. Na maioria das vezes são lesões de tamanho reduzido, localizadas no interior do parênquima encefálico. Angiograficamente não mostram alterações com circulação patológica, podendo mesmo não ser diagnosticados pela tomografia, sendo o exame ideal para o seu diagnóstico a ressonância magnética de crânio. Os cavernomas são lesões histologicamente benignas mas, dependendo de sua localização, podem trazer grandes transtornos neurológicos e ser irressecáveis. A exérese cirúrgica da lesão é o tratamento de escolha se a lesão for única e em localização favorável e estiver desencadeando sintomatologia neurológica prejudicial ao paciente. Apresentamos dois casos de cavernomas gigantes que apresentaram boa evolução após ressecção cirúrgica completa. Descritos como gigantes, foram encontrados apenas três casos individuais na literatura .

Abstract
The authors present a documented sporadic de novo cavernous malformation of the central nervous system (CNS) in a patient undergoing follow-up magnetic resonance imaging after resection of an acoustic neuroma. The authors believe that this is the first report of a de novo cavernous malformation in a patient without a familial history of this disease or a history of treatment with cranial radiation. The occurrence of de novo lesions invalidates the common assumption that cavernous malformations are congenital lesions. The use of this assumption to calculate bleeding risks retrospectively in patients with cavernous malformations is likely to underestimate the risk of symptomatic hemorrhage significantly. Consequently, the de novo formation of cavernous malformations may be more common than appreciated and may explain the higher bleeding rates reported in prospective compared with retrospective studies of these lesions.

Abstract
A case of a left temporo-occipital arteriovenous malformation associated with a pleomorphic xanthoastrocytoma is described. The patient had the vascular lesion with a stable right hemiparesis for many years prior to his recent clinical deterioration. Correlation is made with nine previously reported cases of angiogliomas. With the close proximity and temporal correlation of the two components of this lesion, as well as pathological evidence, the authors propose that angioglioma may be the product of reactive glial proliferation and transformation secondary to a pre-existing vascular malformation and hemorrhage.

Abstract
Ten patients in whom tissue proliferation akin to angioglioma occurred within the brain are described; seven of the lesions were supratentorial and three infratentorial. Only 31 accepted instances of such neoplasms have been found in the literature. The combined lesions usually become symptomatic in the second and third decades. In all 10 cases, the angiomatous part of the combined tumors showed characteristic vascular malformation such as severe hyalinization, tortuosity, and some were even calcified. The number of abnormal blood vessels were excessive in all examples. The glial portion consisted of either astrocytoma, oligodendroglioma, or mixtures of these gliomas. Dedifferentiation of the neuroglia combined with neoplastic endothelial proliferation indicates the true neoplastic nature rather than reactive gliosis associated with a vascular anomaly.

Abstract
Reporting two cases of cavernous angioma closely associated with oligo-astrocytoma we were stimulated to revise the proper use of the term "angioglioma", introduced by Councilman 80 years ago7. In the past this term was often used in a merely descriptive sense i.e. either to give a name to an exceptional coincidence of AVM and glioma or simply to describe a hypervascularized glioma. Today, according to the majority of authors, such a use of this term has to be rejected as inappropriate. Occasionally however the term angioglioma has been used to designate a true mixed composite neoplasm developed after the transformation of both glial and angiogenic elements determined by simultaneously or consecutively acting (even possibly intermingled) oncogenic factors. Among reported cases claimed to be examples of "true" angioglioma, the association cavernomaoligodendroglioma/astrocytoma seems the most intriguing besides being also the most frequent one. Opinions about this topic however did continue to be unequivocal. While some authors regarded the oligodendroglial proliferation associated with AVM as merely reactive or malformative, others considered it as truly neoplastic putting forward the hypothesis of a common viral or genetic aetiology for both AVM and glioma.

Abstract
The authors report a case of cerebral astrocytoma associated with a cavernous angioma. The patient presented with seizures and progressive hemiparesis. Diagnostic studies suggested the presence of a cavernous malformation with signs of previous haemorrhage. Surgery disclosed a complex tumour, which on histological examination revealed to be an anaplastic astrocytoma associated with a cavernous angioma.

Abstract
A newborn is described who presented with heart failure from a posterior dural arteriovenous malformation and had a coexisting congenital medulloblastoma. There have been sporadic reports of arteriovenous malformation and brain neoplasms in older children and adults, and these have generally been glial tumors. This is the first known case of a combined congenital primitive neuroectodermal tumor and arteriovenous malformation in an infant.

Abstract
Chiasmatic/hypothalamic gliomas usually are histologically benign astrocytomas that may recur many years after diagnosis and treatment. Three children with chiasmatic/hypothalamic gliomas who were treated at the authors' institution returned 9.5, 11.5, and 2 years, respectively, after radiation therapy (RT) because visual and neurologic deterioration developed. Neuroradiographic studies, including arteriography in two of the patients, showed large mass lesions. These were presumed to be recurrence of tumor, and chemotherapy was administered. Pathologic examination of two children who died and of the third who had a biopsy revealed only a minimal amount of residual, histologically benign astrocytoma, whereas the bulk of the specimen consisted of numerous vessels of variable size. These probably represented incorporation of the rich vasculature in the chiasmal region into the tumor, which underwent degeneration secondary to RT. Radiographic methods did not distinguish progressive tumor growth from the vasculopathy and led to inappropriate clinical diagnoses and treatment.

Abstract
The term "angioglioma" denotes a highly vascular glioma, most of which are low-grade lesions associated with a favorable prognosis. The authors encountered an example of this pathology, a cystic oligodendroglioma associated with prominent vasculature which both clinically and histologically mimicked an occult arteriovenous malformation (AVM). This case and reports of the association of AVM and glioma prompted a histological review of 1034 surgically resected AVM's, both angiographically occult and visible, among which no oligodendroglial or astrocytic forms of "angioglioma" were found. Eight cases were observed, however, wherein oligodendroglial cells were increased in number within or about the malformation. Two basic histological patterns of oligodendroglial cell excess were seen; one appeared to be malformative in nature with abnormal disposition of oligodendroglial cells being an integral part of the AVM, whereas in the other an apparent increase in cellularity seemed the result of chronic ischemia with condensation of white matter. It appeared that the areas of increased oligodendrocyte content seen in association with AVM are non-neoplastic lesions that exhibit two rather distinct histological patterns of differing origin. In an effort to determine the frequency of "angioglioma," the authors examined Tissue Registry data for several glioma groups in which highly vascular examples are prone to occur. Tumors selected for study included 104 cerebellar-type (pilocytic) astrocytomas, 82 oligodendrogliomas, and 51 supratentorial pilocytic astrocytomas. Histological hypervascularity mimicking a vascular malformation (that is, an "angioglioma") was encountered in 5%, 4%, and 12% of the cases, respectively. Based upon clinical, radiological, and pathological reviews of these cases, as well as a careful review of the literature, it was concluded that 1) "angiogliomas" are neither rare nor represent a distinct clinicopathological entity; 2) in histological but not necessarily angiographic surgical terms, they represent simply highly vascular gliomas, usually of low grade; and 3) the clinicopathological and angiographic features as well as the prognosis of such lesions do not differ from those of similar gliomas without angioma-like vasculature. Finally, "angiogliomas" must not be confused with gliomas of high-grade malignancy which, due to neovascularity, may be highly vascular at angiography and at surgery.

Abstract
Cavernomas are vascular malformations composed of a compact mass of sinusoidal-type vessels that are immediately contiguous with one another and have no intervening parenchyma. Cavernous malformations were previously held to be a rare pathology occurring predominantly in adults. New neuroradiological techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) demonstrate, on the contrary, that these lesions are also more frequent during childhood than was previously thought. In our institution we observed 17 cases of cavernous malformations in patients aged between 18 months and 16 years, 16 of whom were diagnosed after 1982. In 4 of these cases there was a documented familial history; in 2 multiple malformations were present. The most common site was the subcortical frontal region, but in 1 case the malformation was located in the pineal region. The most frequent (in 12 cases) initial symptom was hemorrhage, with the characteristics of an intracerebral hematoma. In 4 cases the initial symptom consisted of epileptic fits and 2 of these patients subsequently suffered hemorrhage. In one case the symptoms observed were those of an expansile process. All our patients underwent cerebral angiography and only in 1 case did this show a vascular abnormality. CT, performed in 16 patients, gave positive results in all cases. MRI, performed in 12 patients, gave highly significant images in all cases. Radical surgical removal of the malformation was performed in 15 of the 17 patients, and the results can be considered excellent in the majority of cases. Cavernous malformations are, therefore, more frequent lesions than had previously been thought, especially in pediatric patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Simultaneous occurrence of a cerebral arteriovenous malformation and a primary brain tumor is rare. A case of a left occipital meningioma and a right parietotemporal arteriovenous malformation is reported. Clinical, radiological, and postmortem findings are described. Thirty previous reports of arteriovenous malformations associated with primary brain tumors are reviewed. In 18 cases the two lesions were intermixed or in close proximity. This spatial relationship between the lesions suggests more than a coincidental association. Several hypotheses are proposed to explain common causal connections.

Abstract
A 9-year-old girl was evaluated for behavioral changes and seizures. Initial computerized tomography and cerebral angiography revealed a left cerebral vascular mass, diagnosed as an arteriovenous malformation. An embolization procedure was attempted but was terminated before completion because the patient developed a right hemiparesis. Her right-sided neurological deficit subsequently increased with enlargement of the mass lesion. On follow-up cerebral angiography approximately 2 years later the vascular malformation was no longer demonstrated. Biopsy of the mass lesion revealed it to be an anaplastic astrocytoma. This case is reported with a review of the literature on the coexistence of a brain tumor and a vascular malformation, the difficulties in diagnosis, and possible etiologies.

Abstract
Cerebral cavernous angioma is a rare vascular malformation at any age and is very rare in childhood. In the literature available to us, we have been able to trace only 50 cases, to which we have added the 6 cases from our own series. The incidence in pediatric group is higher at 0-2 years (26.8%) and at 13-16 years (35.7%). The clinical onset shows epilepsy in 45.4% of cases, hemorrhagic syndrome in 27.3%, intracranial hypertension in 16.4%, and focal neurological deficits in 10.9%. Furthermore, we discuss the neuroradiological features (CT, angiography, and MRI) and the therapy of pediatric cavernous angioma.

Abstract
Five cases of histologically verified cavernous angiomas of the spinal cord are reported. Acute lower-extremity sensory disturbance was the initial symptom in four patients, and one presented with weakness of the hand. Progressive neurological deficit occurred in all patients, but the clinical course and outcome were extremely variable. Myelography revealed an intramedullary lesion in two cases but was completely normal in three; magnetic resonance imaging was diagnostic in these patients. Subtotal removal was accomplished in two cases, and myelotomy and biopsy were carried out in three. Four of the cavernous angiomas were located in the cervicothoracic region, whereas one was found in the thoracolumbar cord. All of the patients exhibited characteristic gross and microscopic features as well as hemosiderin-laden macrophages indicating remote hemorrhage. The diagnostic, therapeutic, and prognostic implications of this rare condition are discussed.

Abstract
The authors review 30 documented cases of intracranial and orbital cavernous angiomas treated at their institution between 1965 and 1984. The diagnosis was based on computerized tomography (CT) or surgery; three patients were treated in the pre-CT era (1965 to 1976) and 27 since the advent of CT. The number of cases diagnosed preoperatively markedly increased after the introduction of CT, and 22 cases were verified histopathologically at surgery. Six cases were in children (aged 2 months to 17 years) and 24 in adults (aged 19 to 73 years). There was no significant sex difference (male:female ratio was 14:16). Nineteen lesions were intraparenchymal, five were intraventricular, three were in the middle fossa, two were intraorbital, and one originated from the tentorium. Symptoms varied according to the site of the lesion; hemorrhage occurred in 11 cases. Calcifications were seen on CT scans in all cases, but on plain skull films in only two. Angiography revealed hypovascular masses in all cases excluding those with lesions in the middle fossa; in two cases, tumor stain could be detected only with prolonged-injection angiography. Radionuclide brain scanning showed a dense hot area in eight of 19 patients. Recent experience has shown that magnetic resonance imaging clarified anatomic relationships that were obscure on CT. The overall outcome was favorable except for one patient who died in the postoperative period. The clinical results in this series are summarized and some diagnostic and therapeutic problems are discussed.
