The Direct calculation of x-dependent parton distribution functions (PDFs) are not possible using ab initio Euclidean-space Lattice QCD, due to their definitions in terms of light-cone coordinates. I present the recent Lattice QCD calculation of pseudo PDFs, a Lorentz invariant generalization of light cone PDFs. These Lorentz invariant functions can be calculated on a Euclidean lattice and related to light cone PDFs in the proper limits. I will discuss the applicability of perturbative formula to the lattice data. I will also discuss methods of extracting the PDF from lattice data over a limited range of momenta and Euclidean-space separations.
