AbstractThe differential diagnosis of abdominal pain in women during their childbearing years is still a challenge. Abdominal pain caused by isolated tubal torsion is extremely rare. In the report, we presented a case of isolated tubal torsion caused by benign serous cystadenoma. A 28-year-old married woman (G0) having lower abdominal pain and nausea was referred to our Emergency Room with suspicion of ovarian mass. Physical examination, transvaginal ultrasound and computed tomography showed a 4-cm right adnexal cystic mass. Other laboratory data were all within normal limits. She was managed by laparoscopic examination due to a lack of improvement in her clinical symptoms and inclusive diagnosis after 48-hours' conservative treatment. Laparoscopy showed isolated torsion of right fallopian tube but the right ovary was normal without torsion. Initially, detorsion was performed but necrotic change of the fallopian tube persisted because of permanent darkened color tube without blood flow redistribution, so salpingectomy was performed 30 minutes later. Final pathology showed benign serous cystadenoma of fallopian tube. The present case is the first case of benign serous cystadenoma with resultant necrotic tubal torsion. We reported this case to emphasize the possible value of early performance of laparoscopy in aiding an accurate diagnosis.
