  It has been suggested that wormholes and other non-trivial geometrical
structures might have been formed during the quantum cosmological era ($t\sim
10^{-43}$s). Subsequent inflation of the universe might have enlarged these
structures to macroscopic sizes. In this paper, spherical geometrical
structures in an inflationary RW background are derived from the Einstein
equations, using a constraint on the energy-momentum tensor which is an
extension of the one expected for inflation. The possibility of dynamical
wormholes and other spherical structures are explored in the framework of the
solutions.
