Crohn's disease with unusual enterouterine fistula in pregnancy

Pregnancy complicated by development of Crohn's disease is rare. The presentation of symptomatic Crohn's disease during pregnancy was initially described in 1946. Crohn's disease has been described in a number of atypical locations and with development of unusual fistulas. The cases associated with pregnancy have in common a clinical picture of (1) delay in diagnosis, (2) frequent premature delivery, (3) surgical intervention during pregnancy, and (4) high fetal and maternal morbidity and mortality. To our knowledge, this case is the first to describe the radiologic findings of an enterouterine fistula in a case of Crohn's disease beginning during pregnancy.
