case_images: Brain MRI according to sagittal T1WI (a), axial T2WI (b), axial FLAIR WI (c)
  and axial T1WI with gadolinium injection (d) showing an intraventricular
  mass of the left lateral ventricle, isointense in T1 sequence with a
  broad-based attachment to the septum pellucidum, abutting the wall of the
  ventricle realizing a scalloping sign (a), isointense to slightly
  hyperintense in T2WI and FLAIR WI (b, c) with a well-defined strikingly
  enhanced areas at gadolinium injection (arrow).

case_images: T2WI with some foci of mild enhancement at the gadolinium injection (Figure 1). The diagnosis of CN was set by radiologists; the patient underwent gross tumor resection, and histological examination confirmed it. The patient is being followed up to this date with no recent symptoms or worsening.
