12C0(J = 1-0) observations of the central region of NGC4258 at a resolution of 17” revealed a high-density concentration of molecular gas toward the center. The molecular clump lies on a central depression in the HI bar. No clear interaction of the molecular gas with the continuum anomalous arms has been found.
