Default A basic question about gravitational Lensing

Can it ever occur in Gravitational Lensing that a mass
distribution which lenses the object acts like a Concave lens and
teh rays of light after passing around the object diverge ?
Can such a situation ever occur in GR (or any other theory of gravity?)
Thanks
Melroy
