Central Neurocytoma

Last Updated: October 1, 2018

Figure 1: This large central neurocytoma demonstrates its typically cystic feature on axial FLAIR (top row left). This image also shows an entrapped right frontal horn indicated by incomplete suppression of CSF. The SWI image (top row right) shows dark susceptibility artifact that likely represents calcifications commonly seen in these tumors. Central neurocytomas typically have some enhancement, but less than many other tumors, as seen on this postcontrast T1WI (bottom).

 

Figure 2: Axial T1 post contrast image (top row left) demonstrates a heterogeneously enhancing mass in the left lateral ventricle which appears inseparable from the septum pellucidum. T2-FS image (top row right) demonstrates the cystic and bubbly appearance of this mass. Enhancing components correspond to regions...
