Spin triplet superconductor UTe$_{2}$ is widely believed to host aquasi-two-dimensional Fermi surface, revealed by first principal calculations,photoemission and quantum oscillation measurements. An outstanding questionstill remains as to the existence of a three-dimensional Fermi surface pocket,which is crucial for our understanding of the exotic superconducting andtopological properties of UTe$_{2}$. This 3D Fermi surface pocket appears invarious theoretical models with different physics origins but has not beendetected experimentally. Here for the first time, we provide concrete evidencefor a relatively isotropic, small Fermi surface pocket of UTe$_{2}$ via quantumoscillation measurements. In addition, we observed high frequency quantumoscillations corresponding to electron-hole tunneling between adjacent electronand hole pockets. The coexistence of 2D and 3D Fermi surface pockets, as wellas the breakdown orbits, provides a test bed for theoretical models and aid therealization of a unified understanding of superconducting state of UTe$_{2}$from the first-principles approach.
