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 (z=3.8). We have detected a component of size not more than 15 mas (≃65pc, H₀=75km/s/Mpc, q₀=0.5) at a distance of ≃2.9kpc 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, 1.5x10⁸M_☉, is consistent with those of subgalactic structures preceding formation of globular clusters in the early stages of the evolution of galaxies.
