  We report TIMMI2 diffraction-limited mid-IR images of the multipolar PPN IRAS
16594-4656. By using the Lucy-Richardson deconvolution algorithm we recover a
two-peaked morphology in the innermost region at 8.6 and 11.5 microns. We
interpret the observed mid-IR structure as the detection of the two
limb-brightened peaks indicating the presence of a dusty toroidal structure in
IRAS 16594-4656. We find that the supposed biconical openings of the dust torus
are in good agreement with one of the bipolar outflows identified in the HST
optical images.
