Slaad tadpole killed, but not disintegrated. Consequences...?

So, after a Slaad encounter, multiple party members were infected with Slaad tadpoles.

The party also found a way to kill them without the normal way of curing the disease and disintegrating the tadpole. They used wither and bloom - however, this has left a dead tadpole rotting in their chest cavity.

What might come of this...? Any ideas welcome.
