10 year old male, free intraperitoneal fluids found in pelvis, greater than the typical male. is this something i should be worried about?

Depends reason 4test: How concerning the finding of increased fluid report on a test result depends on the reason the test was ordered. Reported but unrelated finding may not causing any problem. Too often we order a test for one problem, do not find anything bad, and then need to explain the note of an unusual finding that is completely not a problem. I certainly cannot say if it is a problem for him.
