A nonlinear equation for ion acoustic waves in dense quantum plasmas (which is analogous to the classical plasma case) has been obtained in a particular limit. Therefore it is proposed that electrostatic monopolar and dipolar vortices can appear in uniform dense quantum plasmas due to large amplitude acoustic fluctuations. It is noticed that the scale length of these structures will be very short. The main quantum effect appears through Fermi pressure.
