Is a ectopic pregnancy often mistaken for a cyst?

Hopefully not!: An ectopic pregnancy is suspected in the following setting: 1. A patient is pregnant 2. Hcg levels are rising abnormally 3. Pain is present on one side of the other 4. There is findings on ultrasound of a "mass" or cystic area near one of the ovaries it would be easy to mistake an ectopic for an ovarian cyst if an ob/gyn was not considering an ectopic as a possibility!
