"Most lymphatic malformations appear homogeneous and cystic on CT, but some appear inhomogeneous because of the presence of proteinaceous, fluid, blood, or fat components within the lesion. It is rare for CT to demonstrate intrinsic septations. There is only minimal or no displacement/compression of adjacent structures."
