Background Pilocytic astrocytoma can be challenging to diagnose. Methods Its clinical presentations can differ, directly related to its size and location, and are relatively unreliable. Similarly, imaging findings also vary with the location of the pilocytic astrocytoma. Results This review provides an overview of the different imaging findings regarding pilocytic astrocytomas using both conven...
Following a 5 cm left frontal lobectomy for the removal of a mixed astrocytoma-oligodendroglioma, a 51 year old right handed man showed a marked dissociation between his performance on standard neuropsychological tests and his everyday behaviour. In contrast to his intact neuropsychological test performance, he was impaired on a test of "strategy application" which requires goal articulation, p...
BACKGROUND AND PURPOSE Although the prognostic value of perfusion MR imaging in various gliomas has been investigated, that in high-grade astrocytomas alone has not been fully evaluated. The purpose of this study was to evaluate retrospectively whether the tumor maximum relative cerebral blood volume (rCBV) on pretreatment perfusion MR imaging is of prognostic value in patients with high-grade ...
Pilocytic astrocytoma is a low-grade glioma that occurs mainly in cerebellum of children, and young adults. The article is a rare case report of pilocytic astrocytoma with angiocentric arrangement in the supratentorial region of a 39-year-old female. Immunohistochemical markers, including GFAP, Vimentin, S-100, CD56, NeuN and Olig2, showed positive expression in tumor cells. The proliferation i...
