Adnexal torsion is one of the most common gynecologic surgical emergencies. Delayed diagnosis could result in tissue necrosis, leading to loss of ovarian function and impaired fertility.
The goals of this exhibit are:
1. Review the anatomy of the female pelvis.
2. Discuss the incidence, risk factors, and clinical characteristics of adnexal torsion.
3. Describe the technical approach of performing pelvic ultrasound.
4. Illustrate the sonographic imaging spectrum of adnexal torsion.
5. Discuss diagnostic criteria of adnexal torsion. Read More

Adnexal torsion is the most common gynecological emergency in children and adolescents. Early diagnosis is crucial. The diagnosis of torsion requires a summation analysis of clinical, laboratory, and imaging findings. Adnexal torsion may mimic abnormalities of the gynecological (such as ectopic pregnancy and pelvic inflammatory diseases ), genito-urinary (such as renal or ureteric stones), and gastrointestinal tract abnormalities (mostly, appendicitis and inflammatory bowel disease like Crohn's). Gastrointestinal causes mimicking torsion may also include less likely abnormalities of the upper GI tract, including liver, gall bladder, pancreatic, and ulcer disease. Additionally, rare tumor masses may be a direct cause of ovarian or para-ovarian torsion or may simulate the pain.
We present a spectrum of imaging cases showing simulators of ovarian torsion as well as a spectrum of actual gynecological system torsions, including those of the ovaries and para-ovarian structures in the pediatric population. We review the fundamental potential diagnostic pitfalls that may falsely suggest an adnexal torsion as well as imaging features to help evaluate adnexal and para-adnexal torsion.
Imaging plays a critical role in the diagnosis of adnexal torsion and its simulators. We demonstrate imaging findings of those simulators as well as in adnexal torsion. Our study emphasizes primarily on the use of ultrasound to postulate key imaging points.
Adnexal torsion can take a subacute, intermittent, or chronic course, which may be challenging to diagnose. Prompt early recognition and operative management of this abnormality is essential. Correct and early diagnosis facilitates prompt surgical exploration to prevent ovarian tissue loss and the consequent effect on future fertility.

Isolated bilateral fallopian tube cyst torsion is extremely rare in the pediatric population. We have found no published reports of this entity in a child. Early diagnosis of such cases is crucial for the possibility of fallopian tube salvage surgery and the prevention of irreversible damage. Nonspecific clinical and imaging findings in a few reported unilateral cases in children often make surgical intervention mandatory for the diagnosis.
A 10-year-old girl came to the hospital for acute lower abdominal pain. Ultrasound findings demonstrated two large para-ovarian cysts, contiguous with tortuous and dilated fallopian tubes, suggesting torsion of the tubes. A clinician ordered CT did not add any new information.
The patient underwent a diagnostic laparoscopy that confirms the USG impression of the torsion of the bilateral fallopian tubes. Surgical exploration demonstrated twisting of about 1080 degrees of the hemorrhagic and necrotic right paratubal cyst and tube. The left cyst and tube were torsed at 360 degrees. Right partial salpingectomy, left paratubal cyst aspiration, and detorsion of fallopian tubes was accomplished. The uterus and ovaries were healthy.
Isolated bilateral fallopian tube torsion is extremely rare in the pediatric population with nonspecific clinical and imaging findings. Diagnosis usually requires surgery. Our study showed a case of bilateral fallopian tube torsion that occurred about bilateral paratubal cysts. Visualization of a dilated fallopian tube in the presence of normal-sized ovaries must be concerning for fallopian tube torsion, which can be secondary to a paratubal mass or cyst. Prompt early recognition and operative management of this relatively rare entity may prevent unnecessary tubal resection and improve long term fertility. Read More

Fallopian tube torsion is a rare cause of acute abdominal pain in pediatric patients. Pelvic ultrasound is the first imaging modality utilized to evaluate for pelvic pathology, typically to rule out ovarian torsion. Ultrasound findings of fallopian tube torsion can be challenging, leading to delayed surgical intervention, particularly when ovaries have a normal gray scale appearance and spectral Doppler waveforms. We reviewed the ultrasound features of fallopian tube torsion in a series of surgically proven cases. Read More
