I've been on remicade for 7 years (?) and never had any cysts (that I knew about) and am currently 8 1/2 weeks pregnant.
I DO now have a cyst, I only know that because of the ultrasound. But my sister has a history of ovarian cysts and does not have Crohn's (obviously not on remicade). The two other people in my life that have cysts on a regular basis are also not Crohn's patients so I agree this data sounds fishy.
