摘要：

A non-spherical solution of Einstein's field equations, possessing a naked curvature singularity on the symmetry axis, satisfying the strong curvature condition, is presented. The spacetime admits closed timelike curves which appear after a certain instant of time in a causall well-behaved manner. The matter-energy content radiation fields, coupled with anisotropic fluids, obeying the energy conditions, diverge on the symmetry axis.
