De Vaucouleurs Atlas Description:

NGC 4501 , one of the brightest spirals in the Virgo Cluster , has very complex, multi-armed spiral structure. There is a trace of an inner pseudoring which is fairly open. The morphology of the galaxy is dominated by dust all the way to the center, especially on the near side. The obvious star-forming part of the disk is strongly truncated, a typical morphology in the Virgo Cluster (Koopmann and Kenney 2004).
