Pleural Effusion/Ovarian Cancer

I was dx with ovarian cancer Dec. 2003. I had a recurrence and just finished chemo on Dec 29, 2006. Following a cat scan of abdomen and pelvic they found a small amount of fluid in my right lung and a tiny amount in my left lung, which they called pleural effusion ( I had never heard of it)so now I have a chest x-ray and a cat scan of just my chest in the morning, not sure what happens next.... never expected this especially since I had just finished chemo. Just wondering if anyone else had experienced this.
Thanks Jan
