We present the first high resolution HeII λ4686 images of the high excitation nebula around the WR star Brey 2 in the LMC. This nebula presents a striking morphology: a small arc-like feature some 3.6pc in radius is particularly prominent in the HeII λ4686 line. We further discover a previously unknown faint HeII emission that extends over an area of 22x17pc². An even fainter HeII emission is apparently associated with the interstellar bubble blown by the progenitor of Brey 2. The total HeII flux corresponds to an ionizing flux of 4x10⁴⁷photons/s. Hα, [OIII], and HeI λ5876 images and long-slit spectra are also examined in this letter, enabling us to investigate the detailed physical properties at various locations of the nebula.
