BACKGROUND AND PURPOSE: The differentiation of pilocytic astrocytomas and high-
grade astrocytomas is sometimes difficult. There are limited comparisons in the literature of …

Purpose To present the imaging and perfusion data obtained in nine patients with pilocytic
astrocytomas (PA) and to discuss the original functional issues of this technique. Method …

Objective: To quantify and compare T2 signal and apparent diffusion coefficient (ADC) in
pilocytic and pilomyxoid astrocytoma (PA and PMA) and correlate results with myxoid …

Purpose Imaging findings of pilocytic astrocytoma (PA) vary widely, sometimes resembling
those of high-grade glioma (HGG). This study aimed to identify the imaging parameters that …

PURPOSE: Pilomyxoid astrocytoma (PMA) is a recently described astrocytic tumor that has
been previously diagnosed as pilocytic astrocytoma (PA). The purpose of this study was to …

Objective To determine the magnetic resonance imaging (MRI) characteristics of pilocytic
astro-cytomas and to correlate them with the histopathologic findings. Material and Methods …

Background: On contrast-enhanced magnetic resonance (MR) images, pilocytic
astrocytomas (PAs) are usually well-enhanced tumors that may mimic high-grade gliomas …

Objective: The typical magnetic resonance/computed tomographic imaging appearance of
pilocytic astrocytoma (PA) is that of a cyst with an intensely enhancing mural nodule. The …

Introduction Pilomyxoid astrocytoma (PMA) is a rare WHO grade II tumor occurring most
often in young children. PMA is associated with worse outcome as compared to the …

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 …
