Sonographic findings of complete tubal abortion

Abstract

Ectopic pregnancies, implantation of a fertilized ovum in any location other than within the endometrial cavity, occur in 1-2% of all pregnancies. Despite current enhanced early diagnosis enabled by serum beta-human choriogonadotropin (hCG) levels and high-resolution ultrasound, this clinical entity continues to account for between 2.7 and 6% of all maternal deaths. The most common site of ectopic implantation is the Fallopian tube (>90% of cases), and less commonly in previous Cesarean scar, ovary, cervix, or the abdomen. Complete tubal abortion refers to a tubal pregnancy having been expelled from the distal portion of the Fallopian tube into the peritoneal cavity and may be associated with either considerable hemorrhage, spontaneous resolution, or rarely serve as an initial nidus for an abdominal pregnancy. We present unusual sonographic findings of a complete tubal abortion in a patient with minimal symptomology.
