Paediatric cystic ovarian torsion masquerading appendicitis

Abstract

A 7-year-old girl presented with a 2-day history of right iliac fossa pain, fever and elevated inflammatory markers. Clinical examination supported a diagnosis of appendicitis. The patient was taken to theatre for an open appendicectomy the following morning. Intraoperatively, a right-sided ovarian haemorrhagic cyst with 360 degrees torsion was discovered. The ovary was torted along with the cyst. Both were detorted and the abdomen was closed. The patient was discharged 48 hours later, with gynaecology outpatient follow-up 6-8 weeks later. Paediatric ovarian torsions caused by a haemorrhagic cyst greater than 2 cm are rare. Here, we discuss an atypical presentation of ovarian torsion and how the clinical presentation can mimic appendicitis.
