J Neuroimaging 2021; 32:201-212. [PMID: 34816541 DOI: 10.1111/jon.12948] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 10/25/2021] [Accepted: 10/25/2021] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND AND PURPOSE Astroblastoma is a rare type of glial tumor, histologically classified into two types with different prognoses: high and low grade. We aimed to investigate the CT and MRI findings of astroblastomas by collecting studies with analyzable neuroimaging data and extracting the imaging features useful for tumor grading. METHODS We searched for reports of pathologically proven astroblastomas with analyzable neuroimaging data using PubMed, Scopus, and Embase. Sixty-five studies with 71 patients with astroblastomas met the criteria for a systematic review. We added eight patients from our hospital, resulting in a final study cohort of 79 patients. The proportion of high-grade tumors was compared in groups based on the morphology (typical and atypical) using Fisher's exact test. RESULTS High- and low-grade tumors were 35/71 (49.3%) and 36/71 (50.7%), respectively. There was a significant difference in the proportion of high-grade tumors based on the tumor morphology (typical morphology: high-grade = 33/58 [56.9%] vs. atypical morphology, 2/13 [15.4%], p = .012). The reviews of neuroimaging findings were performed using the images included in each article. The articles had missing data due to the heterogeneity of the collected studies. CONCLUSIONS Detailed neuroimaging features were clarified, including tumor location, margin status, morphology, CT attenuation, MRI signal intensity, and contrast enhancement pattern. The classification of tumor morphology may help predict the tumor's histological grade, contributing to clinical care and future oncologic research.

Abstract
Astroblastoma is a rare primary central nervous system tumor of controversial site of origin. They account for 0.45-2.8% of all primary neuroepithelial central nervous system. It has been reported in paediatric age group with bimodal age distribution affecting more females with male to female ratio being 1:11. Astroblastomas are controversial and challenging tumors in terms of diagnosis and therapeutics. Since it carries an unpredictable disease course it needs a regular follow up even for low grade tumor. Authors have tried various schedules of post op radiotherapy after maximum safe resection. Various chemotherapeutic drugs combination have also been tried without much success. We here report a 35 years old female patient who was diagnosed with high grade astroblastoma referred for post-operative radiotherapy after gross total resection. Since it is extremely rare tumor, its treatment still not well defined and also makes it difficult conduct studies to examine tumor characteristics.

Abstract
PURPOSE Astroblastoma is an uncommon pediatric neuroepithelial tumor. The prognosis and appropriate treatment of astroblastoma were not well understood. Previous reports suggested the best treatment for astroblastoma is surgical total resection. The authors report a case of pediatric astroblastoma that underwent gross total resection with the use of fluorescent guidance by 5-aminolevulinic acid (5-ALA). CASE REPORT A 13-year-old girl presented with the tumor that was well-circumscribed cystic and solid mass with marked gadolinium enhancement in the right occipital lobe. At surgery, fluorescence of the tumor was clearly distinctive from the normal cerebral tissue. All fluorescent tissue including residual cyst wall was removed. Postoperative MRI showed gross total resection of the tumor. No serious side effect or complications occurred. The histopathologic diagnosis was suggestive of astroblastoma. The patients had no evidence of recurrence of tumor without adjuvant radiotherapy during the last 1 year of follow-up time. CONCLUSION 5-ALA is useful to achieve gross total resection including cystic lesion of pediatric astroblastoma. A larger prospective study is warranted to establish the use of 5-ALA in pediatric brain tumor.

Abstract
Background Astroblastoma is a controversial and an extremely rare central nervous system neoplasm. Although its histogenesis has been clarified recently, controversies exist regarding its cellular origin and validity as a distinct entity. Because of its extreme rarity and because its common features are shared with other glial neoplasms, this tumor is prone to misdiagnosis and remains challenging not only in terms of diagnosis and classification but also in the subsequent management. This case report describes a new case of astroblastoma. It discusses clinical, radiologic, pathological, and therapeutic features and differential diagnosis of this rare neoplasm, with a review of the recent literature. Case presentation We report the case of an 8-year-old Moroccan girl who presented with a 1-year history of epileptic seizure, headache, and decreased visual acuity. Cranial magnetic resonance imaging revealed a right occipito-temporal mass. A tumor resection was performed and histological examination combined with immunohistochemical study confirmed the diagnosis of low-grade astroblastoma. Conclusions Astroblastoma is a very rare primary brain tumor. Its diagnosis is often challenging because of the astroblastic aspects that can be found in astrocytic tumors, in ependymomas, and in non-neuroepithelial tumors. Considerable confusion surrounds its histogenesis and classification. The low incidence rate makes it difficult to conduct studies to examine tumor characteristics.

Abstract
Astroblastoma is a rare glial tumor occurring in older children and defined by histological criteria as low or high-grade. We describe two children with high-grade astroblastoma. The first patient, with multiple recurrences of a frontoparietal tumor, died 10 years from diagnosis after progression of the disease despite surgery, radiotherapy and chemotherapy. The second patient underwent subtotal resection of a temporal mass; the residual tumor progressed five months after radiotherapy, but after a subsequent gross total resection the patient is now in complete remission 54 months from diagnosis. Although both patients had high-grade astroblastomas, there were histological differences between the two tumors, in particular regarding the proliferative index, which was 30% and 5–10%, respectively. High-grade astroblastoma is usually treated with surgery and radiotherapy, but may have an unpredictable behavior even when tumor excision is deemed complete. The two cases reported here illustrate the variable clinical course of this rare tumor. The proliferative index may be a useful tool to better define prognosis.

Abstract
Astroblastoma is an uncommon glial tumor with predominant manifestation in the young age. Herein, we report a case of 18-year-old astroblastoma female patient who presented with history of two months headache. Magnetic resonance imaging (MRI) of the brain demonstrated well circumscribed, intra-axial abnormal signal intensity lesion (size=5×4 cm2) in the right parieto-occipital region of the brain. The patient underwent complete surgical resection of the gross tumor, as confirmed by an early post-surgical MRI (i.e., within 24 hours of surgery). Histopathological examination revealed neoplastic lesion exhibiting perivascular pseudo-rosettes with centrally hyalinized blood vessel and focal nuclear pleomorphism. Immunohistochemistry staining illustrated reactivity for glial fibrillary acidic protein and integrase interactor 1 (INI-1). These features rendered the diagnosis of astroblastoma. A comprehensive review of the current literature to summarize the clinicopathological and radiological characteristics, prognostic factors and current treatment strategies of astroblastomas is also presented. Our study would expand the pool of this uncommon tumor towards its better understanding and optimal treatment.

Abstract
BACKGROUND Astroblastoma (AB) is a rare tumor with significant dilemma regarding diagnostic criteria, behavior, and optimum treatment. MATERIALS AND METHODS We searched PubMed, Google Search, and Cochrane Library for eligible studies with the following search words: astroblastoma, high-grade astroblastoma, and anaplastic astroblastoma till July 1, 2016, published in English language and collected data regarding age, sex, site of disease, pathological grade, treatment received, and survival. RESULTS Data of 152 patients were retrieved from 63 publications. Median age was 16 years (range 0-71). Females were affected twice more frequently than male (70.3 vs. 29.7%). Tumors were most commonly located in the frontal (39%) followed by parietal lobe (26.7%). Fifty-two and 25% of the patients had headache and seizure at presentation, 76.3% of the patients underwent a gross total resection, 41 out of 89 had a high-grade tumor, and 56 patients received adjuvant radiation with a median dose of 54 Gy (range 20-72). Adjuvant chemotherapy was used in 23 patients. Temozolomide was the most common drug used in 30% of the patients. A combination of cisplatin, etoposide with vincristine, or ifosfamide was used in 17%. Median follow-up duration was 37 months (range 1-238). Median progression-free survival and OS were 36 and 184 months, respectively. Patients with a higher-grade tumor had significantly worse OS with HR 5.260 and p = 0.001. Forty patients experienced local progression. Sixty-five percent patients underwent surgery while 50% underwent radiation as salvage. CONCLUSION AB has two distinct grades with higher-grade tumors having significantly poor survival. Maximal safe surgery followed by adjuvant radiation and temozolomide should be advocated for these tumors.

Abstract
Astroblastomas are rare, potentially curable primary brain tumors which can be difficult to diagnose. We present the case of astroblastoma in a 73-year-old male, an atypical age for this tumor, more classically found in pediatric and young adult populations. Through our case and review of the literature, we note that this tumor is frequently reported in adult populations and the presentation of this tumor in the elderly is well described. This tumor is an important consideration in the differential diagnosis when managing both pediatric and adult patients of any age who present with the imaging findings characteristic of this rare tumor.

Abstract
BACKGROUND Astroblastoma is a rare tumor of uncertain origin most commonly presenting in the cerebrum of children and young adults. The literature contains only case reports and small series regarding its radiologic features. This systematic review is the largest study of imaging findings of astroblastoma to date and serves to identify features that might differentiate it from other neoplasms. OBJECTIVE This study describes the imaging features of astroblastoma based on a systematic review of the literature and two new cases. MATERIALS AND METHODS We conducted a PubMed and Google Scholar database search that identified 59 publications containing 125 cases of pathology-confirmed astroblastoma, and we also added two new cases from our own institution. Data collected include patient age, gender, tumor location, morphology, calcifications and calvarial changes. We recorded findings on CT, MRI, diffusion-weighted imaging (DWI), MR spectroscopy, positron emission tomography (PET) and catheter angiography. RESULTS Age at diagnosis ranged 0-70 years (mean 18 years; median 14 years). Female-to-male ratio was 8:1. Of 127 cases, 66 reported CT, 78 reported MRI and 47 reported both findings. Not all authors reported all features, but the tumor features reported included supratentorial in 96% (122/127), superficial in 72% (48/67), well-demarcated in 96% (79/82), mixed cystic-solid in 93% (79/85), and enhancing in 99% (78/79). On CT, 84% (26/31) of astroblastomas were hyperattenuated, 73% (27/37) had calcifications and 7 cases reported adjacent calvarial erosion. Astroblastomas were hypointense on T1-W in 58% (26/45) and on T2-W in 50% (23/46) of MRI sequences. Peritumoral edema was present in 80% (40/50) of cases but was typically described as slight. Six cases included DWI findings, with 100% showing restricted diffusion. On MR spectroscopy, 100% (5/5) showed nonspecific tumor spectra with elevated choline and decreased N-acetylaspartate (NAA). PET revealed nonspecific reduced uptake of [F-18] 2-fluoro-2-deoxyglucose ((18)F-FDG) and increased uptake of [11C]-Methionine in 100% (3/3) of cases. Catheter angiography findings (n=12) were variable, including hypervascularity in 67%, arteriovenous shunting in 33% and avascular areas in 25%. CONCLUSION Astroblastomas occur most often in adolescent girls. Imaging often shows a supratentorial, superficial, well-defined, cystic-solid enhancing mass. On CT, most are hyperattenuated, have calcifications, and may remodel adjacent bone if superficial. MRI characteristically reveals a hypointense mass on T1-W and T2-W sequences with restricted diffusion. MR spectroscopy, PET and catheter angiography findings are nonspecific.

Abstract
Background: Astroblastoma is a rare glial neoplastic lesion that affects children and adolescents; its histogenesis remains uncertain. It is considered to account for 0.5% of all glial neoplasms, and two different subtypes have been defined based upon histologic characteristics. Case Description: We present the case of a 9-year-old girl who presented with headache, motor symptoms, and seizures few days before she was admitted to our institution. Computed tomography (CT) and magnetic resonance imaging (MRI) scans showed an intra-axial heterogeneous frontoparietal lesion with a striking “bubbly” appearance in MRI T2-weighted sequences and features of intracranial hypertension. Gross total resection of the tumor was achieved and the histopathologic diagnosis revealed high-grade astroblastoma. We reviewed the current published cases of astroblastoma to highlight the demographic, clinical, radiologic, and pathologic data. Conclusion: Astroblastomas are a distinct clinicopathologic entity, with well-described radiologic, pathologic, and cytogenetic features. Its recurrence is high and efforts must be made to elucidate the role and usefulness of radiotherapy and chemotherapy in these tumors.

Abstract
Astroblastomas are uncommon neuroepithelial tumors of uncertain origin. These occur predominantly in the cerebral hemisphere of young adults and children. They form only 0.45-2.8% of all neuroglial tumors. They can be easily misdiagnosed as they are rarely encountered in clinical practice and share common radiological and histopathologic appearance with other glial neoplasms. A 12-year-old female presented to us with progressive headache and diplopia. Her neurological examination showed right 6(th) nerve paresis with papilledema. Brain magnetic resonance imaging (MRI) revealed well-demarcated, peripherally enhancing solid cystic mass of 6 cm in right parietal lobe with mass effect. She underwent gross total resection of the lesion through right parietal craniotomy. The histopathologic diagnosis was suggestive of low-grade astroblastoma. The patient had no evidence of recurrence of tumor without adjuvant radiotherapy during the last 14 months of follow-up. Supratentorial astroblastomas are very rare tumors. Complete excision without radiotherapy is sufficient in low-grade variants.

Abstract
Astroblastoma is a rare glial tumor with uncertain histopathological origin and unpredictable clinical behavior. We present a case of an 11-year-old girl who presented with headache and blurring of vision for 2 months. A well-demarcated mass was found in the right frontoparietal lobe on a brain MRI. The patient was treated with total tumor resection followed by postoperative radiotherapy. Histologically, the features were suggestive of high-grade astroblastoma. The patient is alive and disease free 23 months after surgery. The characteristic radiological and histopathological features and treatment of this case are described with a literature review.

Abstract
Astroblastoma is a rare primary glial tumor of children and young adults, typically located in the cerebral hemispheres and presenting as a well-circumscribed, nodular, often cystic enhancing mass. The existence of astroblastoma as a distinct clinicopathologic entity has long been debated but is recognized in the 2007 WHO classification of CNS tumors. The grading of these tumors remains unsettled. Currently, no grade has been established and there are no clearly defined diagnostic criteria for low- or high-grade tumors. Astroblastomas in general are thought to have a favorable outcome with low rates of recurrence following gross total resection. We report a case of astroblastoma with 'high-grade/anaplastic' histology in a 12-year-old, previously healthy girl. The patient experienced severe, sudden-onset headache, and quickly became comatose. Head CT showed a massive intraparenchymal hemorrhage in the right frontal lobe with surrounding edema. She underwent emergent posterior frontal craniotomy for decompression and hematoma evacuation. Pathologic examination revealed a sharply demarcated hemorrhagic heterogeneous glial tumor with focal papillary architecture, densely hyalinized blood vessels, and intensely GFAP-positive perivascular cells. The tumor showed unequivocal high-grade features including an elevated proliferative index. The diagnosis of anaplastic astroblastoma was rendered. The patient expired on postoperative day 30. This case illustrates the potential poor outcome of high-grade astroblastoma and highlights the morphologic heterogeneity of this rare neoplasm.

Abstract
OBJECTIVE Astroblastoma is an unusual brain tumor in childhood. Tumor usually arises from cerebral hemispheres. This large tumor is well-demarcated, lobulated, solid or cystic, and therefore, may resemble glioblastoma. Histopathologically, there are two types of astroblastoma: well-differentiated (low-grade) or anaplastic (high-grade). In low-grade astroblastoma, treatment of choice is complete excision. This type of tumor usually does not recur. However, anaplastic tumors can recur despite surgery, radiation, and chemotherapy and may be problematic for clinician. CASE REPORT A 7-year-old female patient presented with an acute onset of vomiting and seizure. Magnetic resonance imaging study revealed a large mass in the left parieto-occipital region. She underwent total excision of the tumor. Histopathologically, the tumor was an anaplastic astroblastoma. Her adjuvant treatment was planned to consist of radiation therapy and cisplatin-based chemotherapy. However, the tumor recurred early in the course, and she died 18 months after diagnosis. CONCLUSION High-grade astroblastomas behave like glioblastoma, as emphasized in this case report. Local control of this type of tumor seems difficult despite surgery, radiation therapy, and cisplatin-based chemotherapy.

Abstract
BACKGROUND The term of low-grade glioma addresses a favorable clinical outcome with indolent histological features in general consideration; however, recent studies underline the inconsistency, which originates from the accumulation of different histologic subtypes in this terminology. The malignant transformation of a low-grade glioma is unusual but presents a poor prognosis. CASE HISTORY We report a case of a 12-year-old boy, who was referred for complaints of recurrent seizures. His physical examination was unremarkable, but it was learned that a peripheral mass lesion located on the left posterior parietal lobe--which had been thought to be a low-grade glioma--had been detected on a magnetic resonance imaging 2 years ago at a different hospital. The patient was then treated with valproate and carbamazepine for the seizures and advised to be followed up without any additional diagnostic and therapeutic studies for his suspected low-grade glioma. A recent magnetic resonance imaging study showed enlargements of the mass and surrounding edema with additional necrosis. Surgical excision of the tumor was performed. After the diagnosis of glioblastoma multiforme, the patient received radiation therapy and chemotherapy with a good clinical recovery without any evidence of residue or recurrence at 12-month follow-up. CONCLUSION The first line treatment modality in the management of low-grade glioma--especially in suitable patients--is clearly surgery. The gross total resection guarantees the distinguishing of the histological types of the low-grade gliomas and reflects the biologic behavior of these tumors. Observation without surgery must be reserved for selected inoperable cases.
