In the 10-dimensional pp-waves background we have found using T-duality a 4-dimensional universe with the closed time-like curves (CTC's) which appear in the region bounded by two coaxial elliptic cylinders. This 4-dimensional universe is similar to the Gödel-type space-time only in this region. Outside of this region the causal pathology does not appear.
