We present the results of a study of the centiarcsecond radio structure at wavelength of 18 cm in the high-redshift galaxy associated with the radio source 4C 41.17 (). We have detected a component of size not more than 15 mas ( pc, km s-1 Mpc-1, ) at a distance of kpc from the nucleus of the galaxy which accounts for 30% of the flux density of the previously known unresolved VLA component. We speculate that the radio component is associated with a clump in the interstellar medium. The estimate of its mass, , is consistent with those of subgalactic structures preceding formation of globular clusters in the early stages of the evolution of galaxies.
