Ct scan showed 1cm cyst on liver. gi ordered ultrasound in 6mnth. do i need 2nd opinion to be sure just a cyst? gi also said afp but no reason why.

When: Cysts are small it can be hard to know with certainty that they are indeed cysts on ct. Either MRI or ultrasound can be used to make a firm diagnosis of a cyst. There is one caveat about ultrasound; it can be hard to find small cysts particularly in larger patients. If you have no history of cancer and all your tests are negative follow-up ultrasound in 6 months is very reasonable.

Depends: A benign liver cyst can be very straight forward to diagnose on a ct, if it is water density on ct measurement, uncomplicated with no internal septations and no enhancement. If so, the workup can stop there. If it not so clear cut , it should be correlated with us. It depends on the radiologists report. Afp is a blood test that can indicate certain types of cancers. Why ordered depends on your hx.
