  We calculate radiative corrections to the quark quasidistribution in lattice
perturbation theory at one loop to leading orders in the lattice spacing. We
also consider one-loop corrections in continuum Euclidean space. We find the
infrared behavior of the corrections in Euclidean and Minkowski space are
different. We explore features of momentum loop integrals and demonstrate why
loop corrections from the lattice perturbation theory and Euclidean continuum
do not correspond with their Minkowski brethren, and comment on a recent
suggestion for transcending the differences in the results. Further, we examine
the role of the lattice spacing $a$ and of the $r$ parameter in the Wilson
action in these radiative corrections.
