Patient Data

Age: 40 years
Gender: Male

There is a well-defined ovoid soft tissue mass within a dilated right lateral ventricle, attached to the septum pellucidum. It demonstrates a low signal intensity on T1WI, iso-to slightly high signal intensity on T2WI/FLAIR with no enhancement on postcontrast sequences. The adjacent portion of the septum pellucidum appears thickened with same signal intensity. Evidence of restricted diffusion on DWI/ADC.

Case Discussion

MRI features of an intraventricular tumor attached to the septum pellucidum, probably central neurocytoma.
