Sub-arcsec images at 3.8 and 11.2µm of the cometary HII region NGC 6334 F are presented. Only the HII region is detected at 3.8µm, while three distinct small diameter sources and a diffuse extended emission are found at 11.2µm. The brightest of the small diameter sources (called MIR 2) is coincident with the HII region. MIR 2 is resolved and shows a cometary shape similar to that observed in the radio continuum. This suggests that warm dust and ionized gas are well mixed in the HII region. The diffuse extended emission is observed in the region where the highest density molecular gas and the central region of the molecular outflow are located. No emission at either wavelength is detected from IRS-I 2, the proposed alternative powering source of the bipolar molecular outflow.
