Isolated Fallopian Tube Torsion in a Pregnant Woman due to a Carcinoid Tumor: A Case Report

Fallopian tube torsion is a rare cause of lower abdominal pain especially in reproductive ages. Clinical symptoms are not specific and include acute and sever lower abdominal pain, nausea, and vomiting. Diagnosis would take place after surgery by acute abdomen signs. Early diagnosis and prompt surgery could help to preserve fallopian tube and is essential to preserve fertility. In suspected cases, surgical treatment should not be delayed, as tubular necrosis and permanent lack of its performance may occur.Case Report: We report a pregnant woman with near-term pregnancy who suffered from recurrent lower abdominal pain for more than 7 months. The diagnosis of fallopian tube torsion and necrosis was made at time of cesarean section due to fetal distress, and salpingectomy was performed. Carcinoid tumor was reported in pathology. This condition is rare and would be in mind as a differential diagnosis of acute abdomen in pregnancy.
