Abstract
Pregnancy in rudimentary uterine horn has been reported to be very rare in literature, and is associated with adverse complications. Furthermore, it is also difficult to diagnose, and in most cases, is diagnosed after being ruptured. A case of ruptured rudimentary uterine horn pregnancy presented at Elsaudi Maternity Hospital (Sudan). Despite her recurrent presentation for persistent suprapubic pain and frequent ultrasound scans, the uterine horn pregnancy was not detected, and the diagnosis was made during laparotomy as her condition started to deteriorate progressively due to massive internal bleeding from the ruptured uterine horn.
 Keywords: rudimentary uterine horn pregnancy, ectopic pregnancy, Mullerian anomalies, early pregnancy complication
Highlights
Mullerian anomalies have been reported to affect about 5–8% of women [1, 2], diagnosed mainly through imaging techniques, such as a 2D/3D ultrasound scan, CT scan, MRI, and combined laparoscopy and hysteroscopy
Pregnancy in communicating rudimentary uterine horn poses a risk of catastrophic complications, including rupture which increases the risk of maternal morbidity and mortality as reported in both case reports [3, 4]
Placenta previa and placenta accrete spectrum can be associated with rudimentary horn pregnancy, which further increase maternal morbidity and mortality, in terms of massive blood transfusion and maternal death
Summary
Mullerian anomalies have been reported to affect about 5–8% of women [1, 2], diagnosed mainly through imaging techniques, such as a 2D/3D ultrasound scan, CT scan, MRI, and combined laparoscopy and hysteroscopy. Live birth rate with Mullerian anomalies depends on the type and its classification, with increased risk of recurrent miscarriage in septate and arcuate uterus. According to the ESHRE classification, there are two types of rudimentary uterine horn, communicating and non-communicating. “Ruptured Rudimentary Uterine Horn Pregnancy: A Case Report,” Sudan Journal of Medical Sciences, vol 16, Issue no. Mohmmed Eltayeb Abdelkhalig Mustafa and Eltayeb Abdelkhalig Mustafa impossible in the non-communicating type. Pregnancy in communicating rudimentary uterine horn poses a risk of catastrophic complications, including rupture which increases the risk of maternal morbidity and mortality as reported in both case reports [3, 4]
