Incidental Finding of Unilateral Ovarian and Fallopian Tube Agenesis During Cesarean Delivery in Patient With Recurrent Pregnancy Loss.

Congenital unilateral agenesis of the ovary and fallopian tube is a rare condition that has been previously described in the literature. While this condition is benign, studies have proposed it could be associated with infertility. The purpose of this report is first to highlight a rare incidental finding of unilateral ovarian and fallopian tube agenesis. Secondly, we aim to discuss the various imaging modalities used for the detection of uterine, ovarian, and fallopian tube defects and their shortcomings. Our case describes a 37-year-old G4P0030 woman with an obstetric history of spontaneous abortion and ectopic pregnancy, presenting at 38 weeks gestational age with polyhydramnios. The patient received routine obstetric care with no abnormalities being reported on routine ultrasonography. Elective cesarean section was performed at which time the incidental condition discovery of unilateral agenesis of the right ovary and fallopian tube was made. This case is unique since the incidental diagnosis of unilateral right ovarian and right fallopian tube agenesis occurred during cesarean delivery instead of through imaging. It is important for patient counseling to understand the typical workup and deficiencies in pelvic imaging concerning congenital anomalies.
