A well-defined nodular and an ill-defined infiltrative pattern coexisted in one KD case. (a, b) Axial T1WI and fat-suppressed T2WI revealed an ill-defined infiltrative lesion (white arrow) and a well-defined nodular lesion (red arrow) as well. (c) On axial fat-suppressed contrast-enhanced T1WI, the infiltrative lesion (white arrow) showed heterogeneous and remarkable enhancement, while the nodular lesion (red arrow) exhibited homogeneous, marked enhancement. (d) DWI showed the infiltrative lesion (white arrowhead) and the nodular lesion (red arrowhead)
