Cervical Pregnancy and Its Differential Diagnosis – Endo - Vaginal 3 Dimensional Ultrasound Evaluation

Abstract

AIM:The purpose of this work is to establish the role of Three Dimensional ultrasound in improving the diagnostic ability in cervical pregnancy and also to differentiate it from other cervical pathologies with increased confidence levels. METHODS: In our unit we came across three cases of cervical ectopic pregnancies which were evaluated by 2D, Colour Doppler and 3Dimensional ultrasound. Other common cervical pathologies were also evaluated with the same protocol. RESULT: In our study three cases of cervical pregnancies were assessed with 3 Dimensional ultrasound along with conventional 2 Dimensional and colour Doppler, 3Dimensional assessment has given a definitive diagnosis in all the cases and it also helped in confidently differentiating other cervical pathologies which mimic cervical ectopic pregnancy. We demonstrated a crater in the ballooned cervix which is considered pathognomonic of cervical pregnancy. We call this as a "Crater Sign". CONCLUSION: We consider 3D demonstration of cervical pregnancy was confirmative and is useful in differentiating other cervical pathologies.
