Parasellar Extraventricular Neurocytoma: Magnetic Resonance and Angiographic Findings

Magnetic resonance imaging demonstrates a well-circumscribed extra-axial mass, exhibiting a hypointense signal intensity (SI) on coronal T1-weighted imaging (a) and, hyperintense SI on T2-weighted imaging (b) with moderate homogenous enhancement on enhanced T1-weighted imaging (c).

Description
Summary:Magnetic resonance imaging demonstrates a well-circumscribed extra-axial mass, exhibiting a hypointense signal intensity (SI) on coronal T1-weighted imaging (a) and, hyperintense SI on T2-weighted imaging (b) with moderate homogenous enhancement on enhanced T1-weighted imaging (c). [...]partial resection was performed. [...]EVN has a distinct morphology, cellularity, proliferation rate, and prognosis with a more diverse spectrum.2 EVN was initially classified as a distinct tumor entity in the 2007 World Health Organization (WHO) tumor classification system and is categorized as a WHO grade 2 tumor.3,4 EVN develops anywhere in the brain, predominantly in the cerebral hemisphere.
