We report the magnetic resonance imaging findings of an adult patient with a biopsy-proven pilocytic astrocytoma with anaplastic features. Pilocytic astrocytomas rarely occur in adults, and presentation with anaplastic features such as rapid mitotic activity, hypercellularity, and atypia is particularly uncommon. Accurate neuroimaging diagnosis is essential, but differentiation from more malignant neoplastic lesions may be challenging. Diffusion tensor imaging may potentially provide information on cell proliferation, vascularity, and fiber destruction, which can have implications for treatment and prognosis. In this case, tractography and fractional anisotropy maps demonstrated displacement of adjacent parenchyma and relatively intact fractional anisotropy, which is more suggestive …

We report the neuroimaging findings of a 26-year-old female patient with a biopsy-proven dysembryoplastic neuroepithelial tumor (DNET). DNETs are an uncommon, usually benign, glial-neural cortical neoplasm of children and young adults who typically present with intractable seizures. DNETs may occur in any region of the supratentorial cortex, but have a predilection for the temporal lobes. Accurate neuroimaging diagnosis is essential since patients with DNET benefit from complete resection. However, accurate differentiation from other cortical lesions may be challenging. Typical conventional Magnetic Resonance Imaging (MRI) features can help in the differentiation from other similar cortical tumors. Diffusion tensor imaging can also …
