Incarceration of a sessile uterine fibroid in an umbilical hernia during pregnancy

On rare occasions, uterine fibroids complicate pregnancy. More commonly, fibroids exert a mass effect that either prevents implantation of an egg or becomes problematic as a fetus grows. Less frequently, pregnancies are affected by fibroid herniation through a fascial defect. Several publications describing herniation of pedunculated fibroids exist, two of which were in umbilical hernia sacs. There is, to our knowledge, only one publication describing the presence of a sessile uterine fibroid in an umbilical hernia. This case report adds to the literature by describing a 34-year-old primigravid woman with an umbilical hernia that contained a sessile uterine fibroid and provides parameters that can be used in the initial evaluation of a pregnant woman with an abdominal wall hernia.
