The purpose of this exhibit is to familiarize the radiologist with the expected ultrasound findings of an ectopic pregnancy after treatment with Methotrexate (MTX) and to increase the radiologist's awareness of potential complications of MTX therapy and possible pitfalls.  

1. How to determine which patients with ectopic pregnancy can best be treated with methotrexate (MTX) will be discussed as well as treatment protocols. Alternative treatments for ectopic pregnancy will also be reviewed (including surgery, sonographically guided percutaneous treatment, and expectant management). 2. Side effects of MTX therapy will be discussed. 3. A review of expected ultrasound findings in patients with ectopic pregnancy following MTX administration with specific regard to a) the location of the ectopic (tubal, adnexal, cornual, and cesarean section scar) b) the variable appearance of the post-treatment ectopic, and c) natural regression/changes of a MTX-treated ectopic pregnancy on serial follow up examinations. 4. Complications associated with MTX treatment including failure with continued growth of an ectopic pregnancy, hemorrhage, and adverse reaction to the MTX will be presented. 5. Pitfalls of post-treatment evaluation will be discussed.
