Isolated torsion of gangrenous fallopian tube: a rare case report

Abstract

Adnexal torsion is a common gynaecological cause of acute abdominal pain; however, isolated fallopian tube torsion without ovarian involvement is very rare. Lack of specific clinical symptoms and imaging features makes the preoperative diagnosis of this disease extremely difficult. We report a case of isolated torsion of haemorrhagic hydrosalpinx. This case was preoperatively diagnosed as right hydrosalpinx with left ovarian cyst and laparotomy was performed due to severe pain abdomen. The correct diagnosis of isolated fallopian tube torsion was made during the surgery. The tortuous fallopian tubes were gangrenous in this case therefore, salpingectomy was performed. Laparotomy finding and pathological examination suggested of necrotic haematosalpinx. Through our literature review and our previous experience, we conclude that explorative surgery is crucial for diagnosis and treatment of isolated fallopian tube torsion. We believe that salpingectomy is the best option for treating the isolated fallopian tube torsion, but further discussion and accumulation of evidence is required for decision regarding weather or not to preserve the affected fallopian tube.
