contents The manuscript is devoted to the boundary behavior of mappings with bounded and finite distortion, which has been actively studied recently. We consider mappings of domains of the Euclidean space that satisfy the inverse Poletsky inequality with an integrable majorant, are open, and discrete. Assume that the image of the boundary of the original domain is finitely connected relative to the mapped domain, and the preimage of the boundary of the latter is nowhere a dense set. Then, under certain conditions on the geometry of these domains, it is proved that the specified mappings have a continuous boundary extension. The result is valid even in a more general form, when the majorant in the inverse Poletsky inequality is integrable over almost all concentric spheres centered at each point. In particular, the obtained results are valid for homeomorphisms as well as for open discrete closed mappings with the appropriate modulus condition.
