We present results of a study of the radio emission field around the best estimate position of the low-latitude EGRET source 2EG J1834-2138. The identification of this gamma -ray source with the gravitational lensed AGN PKS 1830-211 has been recently proposed by \cite[Mattox et al. (1997)]{ma97}. Additional support for this identification is provided here. Contamination produced by the diffuse disk emission has been removed from new radio images of the surrounding region of 2EG J1834-2138 allowing a determination of the fine radio structure. Several previously unnoticed supernova remnants have been found within a few degrees from the gamma -ray source. However, the only strong radio source within the 95% source location confidence contour of 2EG J1834-2138 is PKS 1830-211. In addition, both spectrum and variability analysis of the EGRET data support the identification of both sources.
