Does a ct show a difference between ovarian cyst and ovarian cancer?

Ovarian cancer: A ct of the abdomen and pelvis can give clues but surgery gives the only answers. In general, ovarian cancers are larger, more complex, often involve the omentum and lymph nodes. Ascites (excessive fluid in the abdomen) is often seen on ct also.

Depends.: A cystic ovarian lesion can be a benign cyst or a cystic neoplasm. Even a benign cyst can be difficult to diagnose on ct if it has blood (hemorrhagic) or debris inside it. A ct may not be able to discern a hemorrhagic cyst from a solid tumor. A cyst with a growth along its wall may be suspicious. An ultrasound may be useful. Short term follow may tell if the cyst resolve/improve.
