De Vaucouleurs Atlas Description:

This galaxy is tipped sufficiently from edge-on that we can see some of its disk structure. A weak possible bar, slightly misaligned with the major axis, is the basis for the SAB classification. Still, this is an uncertain interpretation. In a 2MASS image (Jarrett et al. 2003), the nucleus of NGC 4216 is flanked by two bright enhancements that resemble ansae in more face-on bars. Another interpretation is that those enhancements are connected to a ring.

In blue light, the outer disk is partly obscured by near-side extinction, but from the appearance we suspect the presence of an outer pseudoring . The variety is difficult to discern. Another possible feature we can see is an apparent nuclear ring surrounding the small bulge.
