Torsión tubárica aislada como complicación de un quiste paraovárico en el hospital universitario de Santander, Colombia

Introduction: The paraovarian cyst represents from 10% to 20% of the adnexal masses, it generates symptoms when it causes torsion of the annexes but this is rare. The isolated torsion of the fallopian tubes has an incidence of 1 in 1.5 million women. Objective: To show a case of isolated fallopian tube torsion (IFTT) as a complication of a paraovarian cyst at the University Hospital of Santander. Clinical case: A 17-year old female patient who presents pain in lower hemi-abdomen. After performing the ultrasound, a right paraovarian cyst is found. Her symptomatology improves within 24 hours. Therefore, she is discharged after telling her some recommendations. Two months later, she returns because of pain exacerbation caused by an adnexal mass of 5 centimeters. Now, her lab tests are normal but her new ultrasound reports an enlargement in the ovary and thickened fallopian tubes, so a laparoscopy is performed. This test shows that the right fallopian tube is twisted with necrosis and a right paraovarian cyst of 6 x 5cm. Discussion: The diagnosis of paraovarian cyst is usually incidental by ultrasound; but when there is a torsion complication, pelvic abdominal pain associated with nausea and vomiting is presented. When the physical examination is performed, 42.9% of women present an adnexal mass on palpation. The patient of this clinical case shows abdominal pain, including a tangible adnexal mass, which is evidenced by the ultrasound. For this reason, a laparoscopy is performed. The treatment of the paraovarian cyst is the follow-up; however, if it increases in size or there is persistence, it should be removed surgically due to the risk of torsion of its annexes. If it presents torsion, its handling will depend on the state of the tube. So, if at the moment of performing a distortion in it the violaceous color persists, a salpingectomy and a cystectomy must be performed in this patient. Conclusions: The diagnosis of fallopian tube torsion is performed if the patient has clinical symptoms such as acute pelvic abdominal pain, nausea, vomiting and presence of adnexal mass when performing a digital vaginal examination. Laparoscopy is the treatment of choice, and its management with cystectomy and salpingectomy depends on the vascular commitment of the cyst annexes.
