Learning objectives Review the radiological findings on the ultrasound (US) and computed tomography (CT) in ectopic pregnancy.
Read more Background DefinitionEctopic pregnancy is a condition where a fertilized egg implants outside the endometrium of the uterine cavity and poses significant risks if undiagnosed or mismanaged. EpidemiologyIncidence is challenging to estimate due to decreased hospitalizations, increased healthcare visits, and difficulties in accurately counting early pregnancy failures not resulting in delivery or hospitalization. It is thought to affect up to 2% of pregnancies. MortalityEctopic pregnancy is a significant cause of maternal morbidity and mortality. Haemorrhage from ectopic pregnancy is the leading cause of first-trimester...
Read more Findings and procedure details Tubal ectopic pregnancyUS findings US findings in ectopic pregnancy commonly include: The presence of an empty uterine cavity. Additionally, a pseudogestational sac or decidual cyst may be seen, representing a fluid collection centrally located within the endometrial canal, often mistaken for an early intrauterine pregnancy. Other uterine findings can include a decidual cast or a thick echogenic endometrium. A complex extra-adnexal mass or cystic structure surrounded by a thick echogenic ring, corresponding to the “tubal ring” sign. Doppler US may reveal increased...
Read more Conclusion Both US and CT play critical roles in the diagnosis of ectopic pregnancy. US is essential for initial assessment, but CT offers enhanced detail, especially in complicated cases. Accurate interpretation of these imaging modalities is crucial for timely diagnosis and management, ultimately improving patient outcomes.
