Ovarian torsion

Ovarian torsion is a rare problem in the pediatric age group that must be included in the differential diagnosis of any girl with abdominal pain or a pelvic or abdominal mass. Clinical presentation is nonspecific, and diagnosis is based on a high index of suspicion. Ultrasound scan remains the most useful investigation, but blood flow on Doppler examination does not exclude ovarian torsion. Current recommendations of treatment strongly support ovary conservation, and macroscopic appearance of the ovary is not a reliable indicator of the degree of necrosis and potential for ovary recovery. For children with ovarian torsion, laparoscopic detorsion should be performed with strong consideration of oophoropexy. An underlying ovary lesion such as mature teratoma or functional cyst is found in most cases; however, the risk of cancer in these patients is extremely low. If there is concern of a mass or underlying pathology, then follow-up ultrasound, resolution of edema and interval laparoscopic treatment may be required.
