Multimodality imaging review for suspected ovarian torsion cases in children

Ovarian torsion-detorsion in a 10-year premenarchial female with chronic recurrent abdominal pain misdiagnosed as 'ama-afo' in a suburb: A case report

This case involved a 10‐year‐old female with recurrent abdominal pain misdiagnosed as ‘ama‐afo’. Intraoperative findings showed a left‐sided strangulated/gangrenous tubo‐ovarian mass twisted four times on its pedicle.

The Society for Pediatric Radiology Magnetic Resonance Imaging and Emergency and Trauma Imaging Committees' consensus protocol recommendation for rapid MRI for evaluating suspected appendicitis in children

The imaging evaluation of acute abdominal pain in children with suspected appendicitis has evolved to include rapid abdominopelvic MRI (rMRI) over recent years. Through a collaborative effort between the Magnetic Resonance Imaging (MRI) and Emergency and Trauma Imaging Committees of the Society for Pediatric Radiology (SPR), we conducted a survey on the utilization of rMRI to assess practice specifics and protocols. Subsequently, we present a proposed consensus rMRI protocol derived from the survey results, literature review, and discussion and consensus between committee members.

Ovarian torsion: diagnosis, surgery, and fertility preservation in the pediatric population

Ovarian torsion is rare in the pediatric population. Delayed diagnosis can significantly impact fertility. The aim of this review is to highlight current knowledge regarding clinical presentation, diagnosis, surgical management, and follow-up in the pediatric population. Whilst the presentation is often very unspecific, most children will present with sudden severe unilateral pelvic pain associated with vomiting. A key diagnostic test is pelvic ultrasonography, which may help demonstrate an asymmetric enlarged ovary with peripherally displaced follicles. In the pediatric population, ovarian torsion may occur in a normal ovary. However, underlying lesions can be found in half of cases. Benign neoplasms (teratomas or cystic lesions) represent the commonest etiology, with the risk of malignancy being less than 2%. Surgical management should be focused on fertility preservation. This is achievable through ovarian detorsion ± ovarian cystectomy ± oophoropexy to avoid recurrence. Follow-up studies demonstrate excellent recovery rates of detorsed ovaries including those with ischemic appearances. What is Known: • Ovarian torsion is a rare diagnosis in the pediatric population. • Aspecific symptoms and differential diagnoses lead to missed or delayed diagnosis increasing the risk of oophoprectomy and further infertility. What is New: • Reviewing the latest knowledge about clinical presentation, diagnostic, surgical management, and follow-up of ovarian torsion in the pediatric population. • Adiponectin was negatively associated with diastolic blood pressure and HOMA-IR, and chemerin was negatively associated with glucose.

Ovarian Preservation and Recurrent Torsion in Children: Both Less Common Than We Thought

PURPOSE

Surgical management of pediatric ovarian torsion includes total oophorectomy (TO) or ovarian preservation surgery (OPS). This study sought to identify factors contributing to surgical management and readmission outcomes for ovarian torsion.

METHODS

The Nationwide Readmission Database from 2010-2014 was used to identify patients < 18 years admitted with ovarian torsion. Patient factors, hospital characteristics, and readmission outcomes were compared by TO and OPS. Standard statistical analysis was performed and results were weighted for national estimates.

RESULTS

There were 6028 patients (age 13 ± 4 years) identified with ovarian torsion who underwent either TO (50%) or OPS (50%). Patients had secondary pathology of ovarian cyst (41%), benign mass (19%), and malignant mass (0.4%). OPS was more common in teaching hospitals (84% vs. 74% TO, P<0.001), patients < 13 years of age (41% vs. 37% TO, P = 0.001), and those from high-income households (51% vs. 41% TO, P<0.001). The overall readmission rate was 4%, with no difference between surgical approach (4.3% OPS vs. 4.4% TO, P = 0.882). Of those readmitted (n = 265), readmission diagnoses were cyst (10%), malignant mass (9%), benign mass (7%), and torsion (5%). The overall rate of recurrent torsion was 0.2%, with no difference between OPS and TO (< 0.3% vs. < 0.2%, P = 0.282).

CONCLUSION

Half of pediatric patients are undergoing TO for ovarian torsion in the U.S. and disparities exist with the utilization of OPS. There is no difference in rate of readmission or recurrent torsion between surgical approaches, and the overall rate of retorsion is lower than previously reported.
