Size of mass after Methotrexate

Thanks Karen,

It’s definitely scary knowing that there aren’t many resources or studies done on this type of ectopic. My dates of ultrasound and Bhcg are below for reference.

Aug 29 - bhcg 3000 - MTX shot

Sept 2 - bhcg 3180 (day 4)

Sept 5 - bhcg 2300 (day 7)

Sept 13 - bhcg 1300

Sept 14 - TVS (mass 2.5x2.5cm)

Sept 19 - bhcg 260

Sept 19 - TVS (mass 3cm) grew by 5mm

My OB specialist and his team are not concerned about the size as they think it is a reaction from the quickly dying cells as my bhcg levels are decreasing. They say it’s inflammation and swelling. As of last night I haven’t had any more pain. So hopefully that’s the case and it will start to resolve on its own.

In other types of ectopics, from your experience, how much does the mass typically grow initially after MTX ?
