This form of glioma illustrates the discrepancies that may sometimes be apparent between histopathological features and length of postoperative survival. The role of chemotherapy is still uncertain. The best clinical results were obtained after total or subtotal resection of the tumor, followed by radiotherapy. One patient, however, has had an unexpected length of postoperative survival of 11 1/2 years. Three of the 4 patients with tumors of this type available for follow-up died after 1 1/2 to 2 1/2 years, the astroblastomas in 2 of them having converted into a glioblastoma and a gliosarcoma, respectively. The high-grade type consisted of tumors with more anaplastic features. Five of the 8 patients with tumors of this type who were available for follow-up have survived from 3 to 20 years after treatment in 1 patient the tumor converted into a fatal glioblastoma after 4 1/2 years. ![]() The low-grade type comprised tumors with better differentiated and more benign-appearing microscopical features. Two distinct histological types were encountered: low-grade and high-grade. A personal series of 23 astroblastomas was reviewed, adequate postoperative follow-up being available in 13 patients. Their clinical behavior is unpredictable and their prognosis has been regarded as intermediate between that of astrocytomas and glioblastomas. Complete excision without radiotherapy is sufficient in low-grade variants.Īstroblastomas are rare, usually circumscribed, supratentorial tumors of young subjects and are characterized by a perivascular arrangement of the tumor cells. Supratentorial astroblastomas are very rare tumors. The patient had no evidence of recurrence of tumor without adjuvant radiotherapy during the last 14 months of follow-up. The histopathologic diagnosis was suggestive of low-grade astroblastoma. She underwent gross total resection of the lesion through right parietal craniotomy. Brain magnetic resonance imaging (MRI) revealed well-demarcated, peripherally enhancing solid cystic mass of 6 cm in right parietal lobe with mass effect. Her neurological examination showed right 6(th) nerve paresis with papilledema. A 12-year-old female presented to us with progressive headache and diplopia. They can be easily misdiagnosed as they are rarely encountered in clinical practice and share common radiological and histopathologic appearance with other glial neoplasms. They form only 0.45-2.8% of all neuroglial tumors. These occur predominantly in the cerebral hemisphere of young adults and children. The low incidence rate makes it difficult to conduct studies to examine tumor characteristics.Īstroblastomas are uncommon neuroepithelial tumors of uncertain origin. Considerable confusion surrounds its histogenesis and classification. ![]() Its diagnosis is often challenging because of the astroblastic aspects that can be found in astrocytic tumors, in ependymomas, and in non-neuroepithelial tumors. A tumor resection was performed and histological examination combined with immunohistochemical study confirmed the diagnosis of low-grade astroblastoma.Īstroblastoma is a very rare primary brain tumor. Cranial magnetic resonance imaging revealed a right occipito-temporal mass. 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. It discusses clinical, radiologic, pathological, and therapeutic features and differential diagnosis of this rare neoplasm, with a review of the recent literature. This case report describes a new case of astroblastoma. 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. Although its histogenesis has been clarified recently, controversies exist regarding its cellular origin and validity as a distinct entity. Through the crew's friendship, the series imparts important messages about how to embrace differences, model positive relationships and foster healthy habits to be the best good-will ambassadors in the universe.ġ7 Total Episodes on 2 DVDs: Astroblast!
