We investigate the radiatively induced Chern-Simons-like term infour-dimensional field theory at finite temperature. The Chern-Simons-like termis temperature dependent and breaks the Lorentz and CPT symmetries. We findthat this term remains undetermined although it can be found unambiguously indifferent regularization schemes at finite temperature.Comment: To appear in JHEP, 8 pages, 1 eps figure, minor changes and references adde
