Isolated torsion of the fallopian tube: a case report and review of the literature.

Isolated torsion of the fallopian tube is a rare medical emergency, especially in premenarchal girls. We present a 9-year-old girl with right-sided lower abdominal pain. Isolated torsion of the fallopian tube was suspected preoperatively because of the clinical presentation combined with the results of ultrasound and magnetic resonance imaging (MRI). At emergency laparoscopy, the isolated torsion of the fallopian tube could be reduced, and the tube could be salvaged. This case report shows that the use of ultrasonography and MRI or CT is a helpful diagnostic tool to recognize this condition at an early stage. Especially in young girls presenting with abdominal pain, this should be kept in mind, as digital vaginal examination and vaginal ultrasound most often cannot be used in the diagnostic process. In conclusion, because prompt surgical intervention is required to preserve the tube and prevent progression to peritonitis and possible detrimental effects on future fertility, isolated torsion of the fallopian tube should be considered in the differential diagnosis of lower abdominal pain in all female patients regardless of age.
