Leptomeningeal infiltration. Male patient, 15 years old, diagnosed with ALL ended treatment. Axial MRI images of the brain at the level of tempro-occipital region: a axial non-contrast T1WI, b axial T2WI, and c axial FLAIR images show bilateral intra ventricular masses seen filling the temporal horns of both lateral ventricles intermediate signal in T1WI and faint bright signal in T2WI and FLAIR images. Significant periventricular edema is seen eliciting high FLAIR signal. Axial DWI (d) and ADC image (e) show diffusion restriction of intra-ventricular masses. f, g Images axial (f) and sagittal (g) post-contrast-enhanced MRI of the brain show avid enhancement of the intra-ventricular masses
