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.

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 ...

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.

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.

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 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

Brain tumor grading has always been tied to predicting prognosis. Originally, the grading system had four grades, then three-grade systems became popular; now, four grades are in vogue. There is less evidence than might be supposed for the validity of these systems, however.

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.

Current Treatment Options in Neurology, 2013
Standard treatment of anaplastic astrocytoma (AA) in good performance patients consists of maximal safe surgical resection followed by focal, fractionated, external beam radiotherapy (RT) alone or in combination with concurrent and adjuvant temozolomide (TMZ). Since prospective data regarding the use of chemoradiotherapy for AA is lacking, the practice
