Isolated torsion of the fallopian tube in a postmenopausal woman; a rare entity
Isolated torsion of the fallopian tube is an uncommon cause of acute lower abdominal pain. The lack of pathognomonic symptoms, clinical ﬁndings on physical examination, and speciﬁc imaging or laboratory characteristics makes this entity difﬁcult to diagnose preoperatively, which can cause surgical intervention to be postponed. We report a case of isolated torsion of the right fallopian tube in a 58-year-old woman with a history of sexually transmitted infection. In most reported cases, there is no vascular flow on Doppler imaging modalities. We also detected high impedance of vascular flow around the cyst wall. Imaging modalities could not provide a definitive diagnosis. Tubal torsion was diagnosed upon laparotomy.
