Fig. 1

A male patient with MALT lymphoma. Axial fat-saturated T2W image a shows a well-defined isointense mass involving intra and extraconal space and extending to the orbit preseptal space. Axial contrast enhanced T1W image b demonstrates homogenous moderate enhancement, lower than that of extraocular muscles. Pixel-by-pixel colored ADC map c was obtained and then embedded with the axial DWI. The corresponding ADC histogram from VOI d shows a top peak and a slight tail on the right. Whole-tumor mean ADC was 0.692 × 10− 3 mm2/s, ADC10 was 0.520 × 10− 3 mm2/s, skewness was 1.81, and kurtosis was 7.51
