We present a patient who developed rupture of a tubo-ovarian abscess during pregnancy following in vitro fertilization and embryo transfer. Thirty-eight reported cases are reviewed, and transvaginal oocyte retrieval, genital tract infections, endometrioma, and previous pelvic surgery are considered as risk factors for pelvic abscess during pregnancy.
Prolonging gestational duration when an infection situation is allowed is the principle of treatment.
