  A 2-parameter inhomogeneous cosmology in Brans-Dicke theory, obtained by
conformally transforming the Husain-Martinez-Nunez (HMN) scalar field solution
of the Einstein equations is studied and interpreted physically. According to
the values of the parameters it describes a wormhole, a naked singularity, or
else a spacetime containing apparent black hole horizons which appear/disappear
in pairs (as well as a cosmological horizon) as in the original HMN metric. The
reasons why there isn't a one-to-one correspondence between conformal copies of
this metric are discussed.
