[Intact unilateral twin pregnancy--sonographic diagnosis and laparoscopic treatment].

Ectopic twin pregnancy is rare. Most frequently it occurs as a heterotopic pregnancy located simultaneously in the the fallopian tube and in the uterus. An unusual case of an intact unilateral ectopic twin pregnancy in the 7th week of gestation was diagnosed at this early stage by TVS (transvaginal ultrasound). The patient was successfully treated by laparoscopic salpingectomy. A review of the current literature is discussed.
