An Unusual Cause of Abdominal Mass in Pregnancy: Dolichomegacolon

Abstract

Introduction: Dolichomegacolon is a clinical entity that may cause acute abdominal symptoms such as volvulus and dells. In this case report, we present a pregnant woman with dolichomegacolon that mimics an abdominal mass. Case: A 30-year-old woman was admitted to our clinic in active labor. We realized an abdominal mass in the abdomen 10 cm. in diameter. Abdominal ultrasound demonstrated a 12x10 cm sonolucent mass at the left side of the uterus. The patient had a history of previous cesarean sections, so she was delivered by cesarean section. On exploration, a 30-cm segment of descending colon was abnormally enlarged, with a width greater than 12 cm. The colon was waved aside, and a healthy newborn weighing 2850 g. was delivered by cesarean section with inferior transverse incision. The patient was discharged uneventfully on postoperative day 5. Conclusion: Dolichomegacolon should be kept in mind as a possible benign cause of an abdominal mass in pregnant women presenting with abdominal mass.
