6 years ago I had a cyst removed it measured 8cm. It was near but on the outside (not attatched) of my left ovary. I have recently been refferred for a scan and have discovered I have another similar cyst although smaller at 6cm it is in the same position. The doctor says it is a pseudo cyst but I cannot find anything that tells me exactly what that means. I am going for a CT scan soon to find out whether it is inside or outside the ovary. Please does anyone know what a pseudo cyst is?
