Dear friend, welcome and thanks for entrusting your query here at HCM !
It is not worrisome.
There is no cure for it.
Most are benign cysts (fluid filled cavities) and are harmless.
Ocassional one may grow and harbour cancerous growth. Hence monitoring for increasing size is needed.
Uncommonly it may get infected.
So you have nothing to do except following it regularly and seek early attention if any abdominal pain
which has no other origin.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries.
Thank you and Good luck !
