Doppler findings in chronic ectopic pregnancy: case report.
Chronic ectopic pregnancy is an uncommon form of tubal pregnancy manifested as a pelvic mass with minimal symptoms and a low or absent titer of human chorionic gonadotropin. For this reason, most of the reported cases have been diagnosed only after explorative laparotomy. The value of Doppler ultrasonography for preoperative diagnosis of this entity has not yet been established. We report on a 36-year-old patient who was admitted for intermittent right lower quadrant abdominal pain of 3 months' duration, and a right adnexal mass found on pelvic examination. On Doppler ultrasonography, a right complex adnexal mass was demonstrated, characterized by extensive external vascularization, aberrant vessels and arteriovenous shunting, but with no internal blood flow. Explorative laparotomy revealed a right tubal mass adherent to the omentum, and covered by numerous enlarged and tortuous blood vessels originating in the omentum. Pathological examination of the mass revealed a chronic ectopic pregnancy. The possible contribution of Doppler-specific characteristics for the diagnosis of chronic ectopic pregnancy is described and discussed.
