ASTROCYTOMAS OF THE CEREBELLUM
Archives of Neurology And Psychiatry, 1950SINCE Cushing's exhaustive report in 1931,1little has been added to his analysis of the pathologic anatomy and treatment of astrocytomas of the cerebellum. Several authors have stated the opinion that an astrocytoma in this location is an entity among gliomas because these lesions occur most frequently in children, have an unusually long life history ...

Journal of Clinical Oncology, 2017The new 2016 WHO brain tumor classification defines different diffuse gliomas primarily according to the presence or absence of IDH mutations ( IDH-mt) and combined 1p/19q loss.

Astrocytomas are the most common primary brain tumors. We will review recent developments in the understanding of the biology of these neoplasms and recent trials demonstrating promising improvements in the survival of patients with malignant gliomas.Temozolomide along with radiation has become the standard of care for patients with newly diagnosed ...

A 2-year-old Duroc boar was examined because of weakness, ataxia, and blindness. During hospitalization, fever spikes of about 41.6 C (107 F) were recorded every 24 hours. The tentative diagnosis was a space occupying mass in the diencephalon. The boar's condition deteriorated rapidly, so the boar was euthanatized and necropsied.

Astrocytomas represent the most common cerebral tumors in humans and in animals, and the fibrillary cytological subtype is the most frequently observed. In this report and for the first time, a thalamic astrocytoma is described in a chamois showing depressed mentation, pleurothotonus and circling to the right side.

Pilocytic Astrocytoma and Pilomyxoid Astrocytoma
2009Pilocytic astrocytoma (PA) These are circumscribed, slow-growing, and often cystic astrocytic neoplasm, typically with a biphasic compact and loose architecture by histology and corresponding to WHO grade I. Though most are sporadic, there is a well-established association of pilocytic astrocytoma and neurofibromatosis Type 1 with germline ...

Gemistocytic astrocytomas (GA) are a variant of diffuse astrocytomas GII (WHO, 2016). Like all diffuse astrocytomas, GA recur with time, which is often accompanied by malignant degeneretion into the anaplastic astrocytoma GIII or to the secondary glioblastoma GIV.

A 41-year-old man had a 6 x 6 x 5-disk diameter amelanotic tumor in the posterior fundus. The clinical and fluorescein angiographic appearance suggested a benign retinal vascular tumor, although amelanotic choroidal melanoma and retinoblastoma were diagnostic possibilities.

A case of pigmented pilocytic astrocytoma (WHO grade I) incidentally found in a right temporopolar lobectomy specimen is reported. The patient, a 41-year-old woman, underwent surgery because of long-standing complex partial epilepsy of presumed post-traumatic origin. Using immunohistochemistry and electron microscopy, the tumor was shown to be composed

Hemorrhagic onset of pilocytic astrocytoma and pilomyxoid astrocytoma
Brain Tumor Pathology, 2009The incidence of hemorrhagic onset in pilocytic astrocytoma and pilomyxoid astrocytoma, and the clinical and histological characteristics, were compared to other types of neuroepithelial tumors or nonhemorrhagic pilocytic astrocytoma by retrospective review of 445 consecutive neuroepithelial tumors treated at our institute.
