Does a simple kidney cyst require follow up? | POCUS pearls

Are cyst on kidney serious? 1.4 cm. Right kidney..a simple renal cyst?

[@abhilashnephropocus1297]

In general, small simple cysts (less than 3 cm) are harmless and do not need any follow up imaging. They are very common. But its up to your doctor to figure out the cyst characteristics and appropriate follow up.

Does post injury /trauma the cyst becomes abnormally bigger almost 5 to 6 times of original size?

[@abhilashnephropocus1297]

Cyst size can increase due to internal hemorrhage but 5-6 times seems too big. I have never seen. If the bleed is that severe, patient must be in hemorrhagic shock.
