Diagnosis of chronic ectopic gestation by hysterosalpingography

Pelvic ultrasound and human chorionic gonadotropin assays are currently the standard methodology to detect tubal pregnancy. We report a case of infert ility investigated by hysterosalpingography in which a clinically unsuspect ed chronic tubal pregnancy was identified with the predisposing factor of b ilateral salpingitis isthmica nodosa. The radiographic findings of this ver y rare cause of tubal filling defect are shown.
