Looks like you found a grand example of a hoag-like ring galaxy! Seeing as this spiral appears to lie in a cluster, it’s entirely possible a companion gravitationally influenced the galaxy into a ring!

Rings like this are generally caused by gravitational density waves, from a ‘bullet’ galaxy colliding with a disk galaxy.
