In answer to the question about a second CT scan being necessary: your specialist can and should look at you previous CT scan results if for no other reason than to see if there are any noticeable changes, I would request a different diagnostic procedure such as an ultrasound which is less invasive requires no contrast and shows the presence of any 'fluid buildup' among what most CT scans would reveal, before submitting to any type of invasive procedure these results could also be used in comparison with your existing CT scan for diagnostic purposes and involves no radiation, although unless you are pregnant the radiation exposure is insignificant.
