A nonlinear equation similar to the Hasegawa-Mima equation for drift waves in dense quantum plasmas has been obtained. Therefore, electrostatic drift vortices can appear in nonuniform dense magnetoplasmas. These nonlinear structures can be of dipolar form as well as street-type vortices. It is noticed that these structures are formed on very short spatial scales. Further, it is discussed that quantum drift waves can couple with quantum ion acoustic waves, like classical plasmas, if the ion parallel dynamics is also considered.
