Just had a sonogram with multiple hepatic cysts with largest measuring 10 by 12 by 13 centimeters, which could not exclude septations or debris and small cyst in kidney. CT might be of benefit. Is there more cause for alarm with cysts in 2 locations ?
First, as a general concept .... Worry is not going to solve your problems, so the answer is definitely no worries. Having said that, it seems likely from your description that you may be suffering from condition called as polycystic kidney disease which may progress gradually inspire of treatment, finally needing removal of the enlarged n infected kidneys in SOME cases(not all). Those patients will need renal replacement therapy of some form.
