A 40-year-old male with left intraventricular meningioma (benign)
A. Axial T1W image showing well defined hypointense lesion in atrium of left lateral ventricle
B. T2W image showing hyperintense lesion with peripheral edema
C. On contrast enhanced axial T1W images lesion showing homogenous intense enhancement.
D. Axial DWI and corrosponding ADC map showing diffusion restriction with minimum ADC value of being 0.733×10−3 mm2/s
E. T2W* first pass perfusion images showing colour coded rCBV maps along with time signal intensity curve and various parameters with rCBV(negative integral) being 1.9 mL/100 g within the tumor
F. T2W* first pass perfusion images showing colour-coded rCBV maps along with time signal intensity curve and various parameters with rCBV being 0.69 mL/100 g in peritumoral edema
