Abstract
Pediatric intracranial arteriovenous malformations (AVMs) are challenging lesions managed by pediatric neurosurgeons. The high risk of hemorrhage and neurologic injury is compounded by the unique anatomy of each malformation that requires individualizing treatment options. This article reviews the current status of pediatric AVM epidemiology, pathophysiology and clinical care, with a specific focus on the rationale and methodology of surgical resection.

[DOI: 10.12998/wjcc.v11.i33.8071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 10/29/2023] [Accepted: 11/14/2023] [Indexed: 11/24/2023] Open
Abstract
BACKGROUND Cerebral proliferative angiopathy (CPA) is a rare subtype of arteriovenous malformation. It is extremely rare in pediatric patients and has serious implications for developing children. However, reports of these disorders worldwide are limited, and no uniform reference for diagnosis and treatment options exists. We report the case of a 6-year-old with CPA having predominantly neurological dysfunction and review the literature on pediatric CPA.
CASE SUMMARY We report the case of a pediatric patient with CPA analyzed using digital subtraction angiography (DSA) who presented initially with a neurological disorder as the main manifestation. This case is the basis for further discussion of the clinical presentation, pathogenesis, diagnosis, and treatment of CPA in children. After the cerebral DSA, the patient was treated conservatively with sedation, fluid replacement, and blood anticoagulation. She could not cooperate with the follow-up magnetic resonance imaging examination because of her young age, and her family declined further treatment because of the surgery’s high risk. She was followed up for 3 months; her symptoms did not worsen.
CONCLUSION This report of rare pediatric CPA can inform and advance clinical research on congenital cerebrovascular diseases.

Abstract
BACKGROUND Diffuse cerebral angiomatosis (DCA) is a diffuse infiltration of normal brain by complex vascular structures. It differs from arteriovenous malformations (AVMs) that are composed of a nidus of vessels through which arteriovenous shunting occurs without interposed functional brain parenchyma. A rare subgroup of AVMs is diffuse with no recognizable nidus with functional neuronal tissue interspersed within the malformed vessels. We present a rare association of DCA and cerebral arterial aneurysm, which dramatically influenced the patient's prognosis. CASE DESCRIPTION A 43-year-old male patient with right hemispheric diffuse cerebral angiomatosis presented with a ruptured basilar tip aneurysm that was successfully embolised. Unfortunately, the patient developed a locked-in syndrome. CONCLUSION The present report shows a possible association between diffuse cerebral angiomatosis and cerebral aneurysms, but this association appears to be less strong than it is with other AVMs.

Abstract
BACKGROUND Based on angiographic features, a rare subgroup, different from classical brain AVMs, called cerebral proliferative angiopathy (CPA) was suggested by Lasjaunias et al. in 1989. There are only few reports of CPA described from Asia. Liu et al. has described 5 cases of CPA from China. The objective of study was to evaluate the clinico-radiological features of patients with CPA in our cohort and to find out the differences between our study and the study by Lasjaunias and Liu et al. METHODS We retrospectively analysed cases of CPA from March 2012 to April 2020. All radiological images of the patients with AVMs were studied and findings suggestive of CPA were identified. We found 10 patients with CPA out of 272 cases of AVM (10/272) and described the various demographic and clinico-radiological features. RESULTS The age of the patients with CPA in our series varied from 14 to 53 years and the mean age was 28.6 years. There was male preponderance (60%) with male to female ratio of 3:2. The most common presentation was seizure (70%). Intracranial haemorrhage was present in five patients. One patient had cerebral infarction. CONCLUSIONS There were substantial differences in clinico-radiological profile of patients with CPA in our cohort as compared to the study by Lasjaunias et al. and Liu et al. in form of male dominance, higher rate of ICH and seizure. In our knowledge, this is the second largest series of CPA worldwide and the first largest series in Asia.

Abstract
OBJECTIVE Cerebral proliferative angiopathy (CPA) is a rare disease, characterized by a large vascular nidus, diffuse angiogenesis, and intermingled normal brain tissue. Conservative treatment, endovascular intervention, indirect revascularization, and radiotherapy have been applied to treat this disease. However, some cases deteriorate even after non-conservative treatment, and there has been no standard of treatment for this disease so far. In order to build a better treatment strategy, we review literature, present our case and propose an algorithm for managing CPA. METHODS Following the PRISMA principle, we systemically reviewed literature discussing CPA. A case successfully managed with multi-modal treatment is also illustrated. RESULTS A total of 23 articles with 74 cases of CPA were found. Thirty-three patients received single-modal management. These 33 cases include 24 receiving endovascular intervention, 7 receiving indirect revascularization, and 2 receiving radiotherapy. Three of the 33 patients deteriorated clinically, and 1 expired. We present a 6-year-old boy with left hemispheric CPA receiving indirect revascularization, followed by 2 consecutive courses of stereotactic radiosurgery targeting arteriovenous shunts in the left basal ganglia and arteriovenous shunts around the olfactory groove. In the follow-up period of more than 4 years, good collateral formation, improved perilesional perfusion, CPA shrinkage, and symptom relief were all achieved. CONCLUSIONS Based on our literature review and case, we propose an algorithm for the management of CPA and emphasize that multi-modal treatment is necessary for most CPA cases.

Abstract
Cerebral proliferative angiopathy (CPA) is an infrequent vascular malformation. It is composed of a nidus, arterial feeders, and venous drainage. Some special features differentiate it from the common arteriovenous malformations (AVM). The nidus has normal cerebral tissue intermingled and occupies a large portion of the brain. There is a frequent transdural arterial supply. Arterial feeders and draining veins are of small caliber concerning the nidus size. Ischemic strokes are the most common clinical event. Intracranial bleeding when occurs has a worse prognosis due to its high recurrence rate. We have presented two cases of CPA in pediatric patients who required surgical resolution of their acute episode.

Abstract
We are describing a case of a 14-year-old girl who developed acute cerebral infarction which was documented on diffusion-weighted magnetic resonance imaging (DWI). On detailed evaluation, diagnosis of cerebral proliferative angiopathy (CPA) was made. Incidentally, she had capillary malformation on the forehead contralateral to cerebral vascular malformation. To our knowledge, this is the first case of CPA in the literature where DWI abnormality was due to acute cerebral infarction.

Abstract
Mucopolysaccharidosis (MPS) type I is a rare lysosomal storage disorder caused by an accumulation of glycosaminoglycans (GAGs) resulting in multisystem disease. Neurological morbidity includes hydrocephalus, spinal cord compression, and cognitive decline. While many neurological symptoms have been described, stroke is not a widely-recognized manifestation of MPS I. Accordingly, patients with MPS I are not routinely evaluated for stroke, and there are no guidelines for managing stroke in patients with this disease. We report the case of a child diagnosed with MPS I who presented with overt stroke and repeated neurological symptoms with imaging findings for severe ventriculomegaly, infarction, and bilateral terminal carotid artery stenosis. Direct intracranial pressure evaluation proved negative for hydrocephalus. The patient was subsequently treated with cerebral revascularization and at a 3-year follow-up, the patient reported no further neurological events or new ischemia on cerebral imaging. Cerebral arteriopathy in patients with MPS I may be associated with GAG accumulation within the cerebrovascular system and may predispose patients to recurrent strokes. However, further studies are required to elucidate the etiology of cerebrovascular arteriopathy in the setting of MPS I. Although the natural history of steno-occlusive arteriopathy in patients with MPS I remains unclear, our findings suggest that cerebral revascularization is a safe treatment option that may mitigate the risk of future strokes and should be strongly considered within the overall management guidelines for patients with MPS I.

Abstract
BACKGROUND Cerebral proliferative angiopathy (CPA) is a rare subset of arteriovenous malformations (AVM). It has unique clinical presentation, angiographic characteristics, and pathophysiology which often brings challenges for the treatment. We aimed to define its epidemiology, pathophysiology are unknown, and best management strategies. METHODS A systematic review was conducted according to the PRISMA guidelines. MEDLINE was searched for articles regarding CPA. Extracted data included epidemiological, clinical, and angiographical characteristics, treatment, and outcomes. Treatment was classified as conservative, radiosurgery, endovascular, decompression, and indirect vascularization. A meta-analytical approach was employed for description of the data as study-size adjusted percentages or weighted means, as appropriate. RESULTS Thirty-three studies were analyzed, rendering a total 95 cases-half of which came from a single study. Patients were predominantly young (mean 23 years old) and female (60.0%) presenting with headaches (44.9%), seizures (37.1%), or transient ischemic attacks (33.7%). Hemorrhage was present in 18.0%, but rebleeding rates were as high as 67%. The majority of nidus were > 6 cm (52.5%) with hemispheric extension (73.0%). Capillary angioectatic appearance (85.7%), transdural supply (62.5%), and deep venous drainage (73.0%) were also frequent features. Most patients were treated conservatively (54.4%), followed by endovascular (34.2%). Indirect vascularization and radiosurgery were attempted in five and two patients, respectively. Mean follow-up was 110.8 patient-years. Neurological status improved in 50.7%, remained stable in 40.2%, and worsened in 9.0%. CONCLUSIONS Conservative and endovascular treatments seem adequate interventions, despite limited evidence. Complementary techniques can be used in patients throughout disease history, according to symptom-based, individualized approach. More studies are required for choosing interventions based on reliable long-term results.

Abstract
Cerebral proliferative angiopathies (CPAs) are distinct vascular malformations with varied clinical presentations and radiological findings from arteriovenous malformations (AVM) (Lasjaunias et al. in Stroke 39(3):878-85, 2008). They usually manifest with seizures if present supratentorial, headache, and progressive neurological deficits due to steal phenomenon or rarely with hemorrhage (Lasjaunias et al. in Stroke 39(3):878-85, 2008). Most of the patients are usually young females. Pediatric cases are extremely rare, with few cases reported till now. Here we report a child who presented with cerebellar bleed and diagnosed as CPA. The child was managed medically, and there was no change in caliber of the vessels after 18 months of follow-up. A short review of cases of CPA in pediatric age group presentations and management was undertaken in this case report.

Abstract
We previously reported a patient with cerebral proliferative angiopathy (CPA) who showed cerebral ischemia in resting and acetazolamide-stressed N-isopropyl-p-[123I] iodoamphetamine single-photon emission computed tomography (123I-IMP-SPECT). At onset, the patient was treated conservatively. However, during the 2 years following initial onset, his hemiparesis and aphasia had gradually aggravated and his IQ scores were markedly decreased. MRI revealed progressive vascular proliferation and brain atrophy. 123I-IMP-SPECT showed more severely impaired cerebral blood flow (CBF) and cerebrovascular reactivity over the affected hemisphere. We performed an indirect revascularization to augment CBF; however, his neurological deficits were not improved and new arteriovenous shunts via extracranial-intracranial bypass were developed, followed by an asymptomatic small intracerebral hemorrhage. There are no reports on CPA patients who have shown cerebral hemorrhage after indirect revascularization. Treatments for CPA are still challenging and controversial. Cases with severe stenosis of the proximal arteries may benefit from indirect revascularization. But indirect bypass should not be indicated for such patients without main arterial stenosis, even if they have persistent ischemia.

Abstract
OBJECTIVECerebral proliferative angiopathy (CPA) is considered a discrete vascular malformation of the brain separate from classical brain arteriovenous malformations (AVMs). It has unique angiographic characteristics and has been hypothesized to result from chronic cortical ischemia and perinidal oligemia. Treatment with cerebral revascularization has been proposed in an attempt to disrupt regional hypoperfusion and interrupt the angiogenesis that defines CPA. A systematic review of the literature pertaining to the role of cerebral revascularization may highlight a treatment paradigm for this rare disease.METHODSA systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. MEDLINE and Embase were searched from inception for papers relating to CPA. Included articles were categorized according to methodology (case series or imaging study) and treatment modality (conservative, radiation, endovascular, or revascularization). A synthesis was compiled summarizing the current evidence regarding cerebral revascularization in CPA.RESULTSThe initial search revealed 43 articles, of which 28 studies met the inclusion criteria. Nine studies were identified that described imaging findings, which suggested hemodynamic dysregulation and perinidal impairments in the cerebrovascular reserve could be identified compared to unaffected hemispheres and classical brain AVMs. Six studies including 7 patients undergoing indirect forms of cerebral revascularization were identified. Clinical and radiological outcomes following revascularization were favorable in all but one study.CONCLUSIONSA small body of radiological and clinical studies has emerged, suggesting that CPA is a response to perinidal oligemia. While the long-term clinical efficacy of revascularization remains unclear, early results suggest that this may be a novel treatment paradigm for patients with CPA.

Abstract
Cerebral proliferative angiopathy (CPA) is a rare vascular abnormality and separate from "classical" brain arteriovenous malformations. Haemorrhage due to proliferative angiopathy is rarely reported. We describe the clinical features, imaging findings and targeted endovascular management for a 12-year-old boy having proliferative angiopathy of the posterior fossa presenting with haemorrhage. Targeted endovascular embolisation in CPA is not previously described in the literature. The optimal treatment options for haemorrhagic CPA are debatable, and we wish to highlight the role of targeted treatment for culprit focal lesion demonstrable on imaging.

Abstract
Cerebral proliferative angiopathy (CPA), which is characterized by diffuse vascular abnormalities with intermingled normal brain parenchyma, is a rare clinical entity distinct from classical cerebral arteriovenous malformations. Its pathology at initial state and subsequent course of progression has totally been undetermined. We herein presented a case of a child who was initially diagnosed with deep-seated arteriovenous fistula (AVF), and ultimately developed symptomatic CPA-like vascular lesion over a long period of clinical follow-up. A 7-month-old boy was incidentally found to have an AVF in the right basal ganglia and conservatively followed up. Serial magnetic resonance angiograms revealed the gradual proliferation and enlargement of pial and medullary vessels surrounding the AVF. Seven years later, he had a transient ischemic attack followed by intraventricular hemorrhage. A catheter angiogram showed a diffuse large vascular malformation composed of 2 distinct structures, including AVF in the right basal ganglia and the surrounding proliferated pial and medullary arteries in the right hemisphere. Single-photon emission computed tomography with N-isopropyl[123I]-p-iodoamphetamine revealed apparent hemodynamic compromise on the right hemisphere. Targeted embolization of the pseudoaneurysm originating from the right A1 perforator was performed to prevent rebleeding without complications. The patient had no further cerebrovascular events. Perinidal hypoperfusion induced by a deep-seated AVF could be one of the underlying pathologies of progressive angiogenic activity. This is the first case showing the development of abnormal hemispheric vascular networks mimicking CPA, which offers insight into the pathogenesis of this new entity.

Abstract
Familial gigantiform cementoma is an exceedingly rare but distinct subtype of cemento-osseous-fibrous lesion. Undocumented radiographic changes and related bone metabolism disorder are herein hypothesized and discussed. We present an adolescent case with recurrent familial gigantiform cementoma who received surgical intervention in our hospital. Apart from typical multiquadrant and expansile abnormalies involving both jaws, he also suffered from several times of fractures in lower extremity. Furthermore, radiographic examinations of calvaria, pelvis, femoris, tibia, and fibula all revealed radiolucent areas signifying diffuse osteopenic bone losses. Some of his consanguineous relatives bore the same burden of fractures during pubertal period.Considering these polyostotic conditions, a correlation of congenital bone metabolism disorder in cases with familial gigantiform cementoma, named "calcium steal disorder," was thus proposed. Familial gigantiform cementoma is closely associated with "calcium steal disorder." Whole-body dual-energy absorptiometry should be considered as a routine examination for fracture-related risk prediction.

Abstract
PURPOSE Here we present our experience with five cerebral proliferative angiopathy (CPA) patients to better delineate the clinical and angiographic features as well as the treatment selection of this disease. METHODS Between October 2008 and October 2012, five consecutive patients diagnosed with CPA were admitted to our department in our hospital. All the five patients received magnetic resonance imaging, digital subtraction angiography, and positron emission computed tomography (PET) to definitively confirm this disease. We also collected 15 previously published instances of CPA to analyze the characteristics of this rare entity. RESULTS As to the five patients, three were female and two were male, between the ages of 4 and 52 years with a mean age of 24.8±20.6 years. The PET results showed that perfusion was decreased over the affected hemispheres in all five patients. As to the treatment, only one patient received encephalo-duro-arterio-synangiosis (EDAS) revascularization surgery. The other four patients were conservatively observed. During the follow-up period (range 3-6 years, mean 4±1.9 years), the patient who underwent EDAS surgery manifested relief of clinical symptoms. In the conservative series, the symptoms in two patients aggravated and suffered permanent neurologic deficits. CONCLUSION CPA is a rare entity. Natural history has showed this disease is not stable and may progress at a certain time point. The EDAS procedure may be a treatment for CPA-related oligemia since there is currently little data and follow-up available.

Abstract
Cerebral proliferative angiopathy (CPA) is a rare clinical entity. This disorder is characterized by diffuse vascular abnormalities with intermingled normal brain parenchyma, and is differentiated from classic arteriovenous malformations. The management of CPA in patients presenting with nonhemorrhagic neurological deficits due to cerebral ischemia is challenging and controversial. The authors report a case of adult CPA with cerebral ischemia in which neurological deficits were improved after encephaloduroarteriosynangiosis (EDAS). A 28-year-old man presented with epilepsy. Magnetic resonance imaging and angiography showed a diffuse vascular network (CPA) in the right hemisphere. Antiepileptic medications were administered. Four years after the initial onset of epilepsy, the patient's left-hand grip strength gradually decreased over the course of 1 year. The MRI studies showed no infarcts, but technetium-99m-labeled ethyl cysteinate dimer ((99m)Tc-ECD) SPECT studies obtained with acetazolamide challenge demonstrated hypoperfusion and severely impaired cerebrovascular reactivity over the affected hemisphere. This suggested that the patient's neurological deficits were associated with cerebral ischemia. The authors performed EDAS for cerebral ischemia, and the patient's hand grip strength gradually improved after the operation. Follow-up angiography studies obtained 7 months after the operation showed profound neovascularization through the superficial temporal artery and the middle meningeal artery. A SPECT study showed slight improvement of hypoperfusion at the focal region around the right motor area, indicating clinical improvement from the operation. The authors conclude that EDAS may be a treatment option for CPA-related hypoperfusion.

Abstract
We describe a case of brain cortical reorganization after embolization of a large right temporal arteriovenous malformation. A comprehensive imaging protocol, including functional magnetic resonance imaging (fMRI), cortical thickness analysis and 320-row computed tomography (CT) perfusion was used to provide information on brain plasticity and potential steal phenomenon. A 25-year-old man known for a right temporal grade V Spetzler-Martin classification arteriovenous malformation (AVM) presented with left progressive hemiparesis. He underwent functional 3T magnetic resonance imaging (fMRI), cortical thickness analysis, and CT perfusion (CT 320 row, Aquilion ONE, Toshiba, Tokyo, Japan) before and after endovascular treatment. The results were compared to look for modifications in brain perfusion and organization. An improvement in the left hemiparesis and a reorganization of motor function were observed after endovascular treatment. Modifications in the angioarchitecture and perfusion of an extensive AVM may be accompanied by a functional and structural reorganization of the brain. The location in the so-called eloquent regions may not be sufficient to explain the wide spectrum of symptoms that these patients can present. A more comprehensive approach considering a global involvement of the brain in patients with large AVMs is suggested to achieve the best treatment strategy and to stage treatment in incurable AVMs.

Abstract
OBJECT Cerebral proliferative angiopathy (CPA) has been morphologically distinguished from classically appearing brain arteriovenous malformations (AVMs) by exhibition of functional brain parenchyma that is intermingled with abnormal vascular channels. The presence of oligemia in this intralesional brain tissue may suggest ischemia, which is not detected in classic brain AVMs. The authors hypothesized that patients with CPA would exhibit a greater impairment of cerebrovascular reserve in neuronal tissue surrounding the true nidus compared with those with brain AVMs. METHODS Four patients with CPA, 10 patients with brain AVMs and seizures, and 12 young healthy individuals were studied. The 4 patients with CPA underwent blood oxygen level-dependent MR imaging examinations while applying normoxic step changes in end-tidal CO(2) to obtain quantitative cerebrovascular reactivity measurements. RESULTS Patients with a CPA lesion exhibited severely impaired perilesional cerebrovascular reserve in comparison with patients with brain AVMs and seizures (0.10 ± 0.03 vs 0.16 ± 0.03, respectively; p < 0.05), and young healthy individuals (0.10 ± 0.03 vs 0.21 ± 0.06, respectively; p < 0.01). CONCLUSIONS This study demonstrated severely impaired cerebrovascular reserve in the perilesional brain tissue surrounding the abnormal vessels of patients with CPA. This finding may provide an additional means to distinguish CPA from classic brain AVMs.
