Isolated Torsion of the Fallopian Tube: a case report

Aims: Isolated torsion of the fallopian tube is a rare condition. A case of isolated torsion of the left fallopian tube associated without anomaly and pathology was present. Patient Methods: The patient was 17-year-old nulligravid from Yasuj who came to the obstetric department with acute severe abdominal pain, nausea, and vomiting in 2021. Her medical history included a left side ovarian cystectomy one year before admission. The pregnancy test was negative. Transvaginal ultrasonography showed a hemorrhagic cyst structure measuring 4cm in the left adnexa with moderate free fluid in the cul-de-sac was noted; the ovaries and uterus were unremarkable. Due to acute abdominal pain, an exploratory laparotomy was done and confirmed the diagnosis of isolated torsion of the left oviduct. The ipsilateral ovary appeared normal, but the fallopian tube was gangrenous, and left salpingectomy was performed. Findings: Due to acute abdominal pain, an urgent laparotomy was performed, which revealed a twisted left fallopian tube and confirmed the isolated torsion of the left oviduct. The ipsilateral ovary appeared normal, but the fallopian tube was gangrenous, and left salpingectomy was performed, and she was discharged from our hospital two days later. Conclusion: Women, without any abnormality and pathology of the tube, with a history of ovarian cyst surgery at the antimesenteric level, that the ovarian fimbria was removed are at risk for fallopian tube torsion.
