axial TV ultrasound through fundus axial TV ultrasound through mid uterus

Findings

Transverse images of the fundus and mid portion of the uterus were obtained using a transvaginal probe. An approximately 5 week gestational sac with a visible yolk sac is noted off-center to the patient's left.

Diagnosis

Gestational sac within a bicornuate uterus

Discussion

A bicornuate uterus is a developmental anomaly in which the Mullerian fails to completely fuse resulting in two uterine cavities of varying degree of division. Pregnancies in a bicornuate uterus are at a higher risk than normal for spontaneous abortion and premature delivery.
