Isolated Torsion of the Distal Part of the Salpinx in a 12-year-old Adolescent

Although in the case of acute low abdominal pain, the possibility of a torsion of the uterine adnexa should be verified, it is very rare to find torsion of the salpinx in an adolescent. Moreover, accurate diagnosis is delayed as it is often confused as torsion of the ovarian cyst or appendicitis. More often than not, diagnosis is made through emergency operations, and the salpinx is often resected. A 12-year-old girl was admitted to our hospital with pain in the lower abdomen, and transrectal ultrasound showed the mass having a longitudinal shape with a septum. After the patient was admitted, a diagnostic laparoscopy was performed following gradually increasing tenderness and rebound tenderness as well as a nonspecific mass observed near the left ovary. During the laparoscopy, torsion was diagnosed in the left salpinx and a salpingectomy was subsequently performed. Therefore, the possibility of torsion of the salpinx must be considered when an adolescent is admitted to the hospital with acute low abdominal pain.
