Diagnosis and Management of ‘Cornual’ Pregnancies from 2002 to 2015 at a Tertiary Referral Centre in South India: Insights from Introspection

Original Article



Interstitial, angular and rudimentary horn pregnancies have all been referred to as cornual pregnancies despite definite diagnostic criteria. Angular pregnancies can be followed up expectantly under close surveillance while interstitial and rudimentary horn pregnancies are terminated by medical or surgical methods. This study aimed to assess accuracy of ultrasound in the diagnosis of ‘cornual pregnancy’ and evaluate management.


Data pertaining to clinical features, ultrasound findings and treatment modalities of the aforementioned conditions between January 2002 and December 2015 at a tertiary perinatal centre were retrieved from the medical records. The ultrasound images and surgical videos were reviewed by the authors.


Of 62 cases, 35 were interstitial, 26 were angular/eccentric intrauterine, and 1 was a rudimentary horn pregnancy. The accuracy of ultrasonography in the diagnosis of interstitial and angular pregnancies was 71.0 and 46.8%, respectively. Medical management was successful in 33.3% of interstitial pregnancies. Fifteen women with interstitial pregnancy had subsequent pregnancies and nine (75.0%) were Caesarean deliveries. Rupture and recurrence rates of interstitial pregnancy were 34.2 and 2.9%, respectively. The rudimentary horn pregnancy was managed by laparoscopic excision followed by a subsequent term delivery.


This study identified frequent occurrences of imprecise nomenclature that resulted in mismanagement of a few potentially viable angular pregnancies. It is imperative for clinicians and sonologists to use unambiguous nomenclature and avoid the term ‘cornual pregnancy’ altogether.
