A giant ovarian cyst torsion: Case report.

INTRODUCTION: Adnexal torsion (AT) is one of a gynecological condition characterized by an acute abdomen. Clinically, a giant ovarian cyst torsion with a diameter of 30 cm is rare. Therefore, an accurate and timely diagnosis and treatment are important.

PATIENT CONCERNS: A 25-year-old unmarried female, presented to the emergency department with intermittent abdominal cramps after a sudden change in position. Considering her symptoms and examination, ultrasound, and magnetic resonance imaging (MRI) results, ovarian cyst torsion was suspected.

DIAGNOSIS: Giant ovarian cyst torsion.

INTERVENTIONS: Surgical intervention with exploratory laparotomy was performed immediately.

OUTCOMES: Intraoperatively, we found a 30-cm left ovarian cyst with a clear root. The left fallopian tube, infundibulopelvic ligament, and ovarian ligament were twisted 900 degrees. Finally, the pathological report revealed mucinous cystadenoma.

CONCLUSION: Giant ovarian cyst torsion with a diameter of 30 cm is rare. Considering her symptoms and examination, ultrasound, and MRI results, ovarian cyst torsion was suspected. The patient was successfully treated using emergency surgery.
