Presentation of a Mullerian anomaly with outflow obstruction after tubal ligation

Objective: To report an unusual presentation of a patient with unicornuate uterus and a noncommunicating functional rudimentary horn and discuss related patient management issues. Setting: University hospital. Patient: A 27-year- old woman who presented with cyclic abdominal pain after a postpartum tubal ligation. Intervention: Diagnostic studies followed by a laparotomy and resection of the rudimentary horn. Results: Resolution of patient's symptoms. Conclusions: Patients with a unicornuate uterus and a rudimentary horn recognized for the first time during a tubal ligation require individualized management depending in part on the precise nature of the horn.
