.
If you take an early type disk with enough magnetic field (and ionization) to have the AEI on. We obtain the following scattered light image of the disk
.
If you take a disk around 150 AU and a brown-dwaaf /10 Jupiter mass planet you get the following disk. on the left in the case of a circular orbit for the compagnon, and on the right for e=0.16. At the origin the disk has similar characteristic for both simulation.
