We derive an exact solution to the Einstein's equations with a stress-energy
tensor corresponding to an opposite-sign scalar field, and show that such a
solution describes the internal region of a rotating wormhole. We also derive
an static wormhole asymptotically flat solution and match them on both regions,
thus obtaining an analytic solution for the complete space-time. We explore
some of the features of these solutions.Comment: Sign of the exponential in equation (10) has been changed. Some typos
