Unusual but yes.: CT scans have limited resolution. They do NOT see everything. Usually large pleural effusions come from significant disease, but not always cancer. The only way to tell is to have the pleural effusion drained & sent for cytology & other testing (culture). The lab techs can spin down the fluid, isolate cells or bacteria that may be causing it. Talk to a pulmonologist or your primary doc. Good luck!

Explanation : No pleural effusion On CT means that you do not have massive effusion. All other questions should be discussed with your doctor, not on line without CT result.
