Presentation transcript:

Coronal (A) and axial (B) contrast-enhanced T1-weighted MR images and an axial DWI (C) and ADC map (D) in a patient with primary dural B-cell lymphoma (arrows) with tumor spread below the skull base (open arrow). Coronal (A) and axial (B) contrast-enhanced T1-weighted MR images and an axial DWI (C) and ADC map (D) in a patient with primary dural B-cell lymphoma (arrows) with tumor spread below the skull base (open arrow). The contrast-enhancing tumor at the caudal surface of the left temporal lobe (A and B) displaces the temporal lobe cranially and resembles a meningioma. DWI reveals restricted diffusion within the tumor with high signal intensity on DWI (C) and corresponding low signal intensity on the ADC map (D). I.S. Haldorsen et al.
