Ovarian torsion in utero diagnosed at 37 weeks of pregnancy: A case report.

Case Rep Womens Health 2020 Jul 12;27:e00232. Epub 2020 Jun 12.

Department of Obstetrics and Gynecology, Henry Ford Hospital, Detroit, MI, United States of America.

Background: Fetal ovarian masses are common abdominal anomalies in female fetuses, often diagnosed in the third trimester. Most masses are benign and tend to resolve spontaneously within a few months after birth, but larger masses may present complications such as torsion.

Case: A 21-year-old primagravid woman was noted to have a complex avascular solid mass in the fetal left pelvis, which was consistent with complex fetal left ovarian torsion. Read More

Department of Pathology, Faculty of Medicine, Federal University of Rio de Janeiro (UFRJ), Rio de Janeiro, Brazil.

BACKGROUND Granulosa cell tumor of the ovary is very rare in childhood; its most common clinical manifestation is isosexual precocious puberty. Clinical presentation as acute abdomen due to pain and ovarian torsion is rare, but a granulosa cell tumor must be suspected in a patient with this acute presentation and signs of early puberty. Adult-type granulosa cell tumor is an even rarer occurrence in children. Read More

Twisted Teeth: Ovarian Torsion Secondary to Mature Teratoma.

Cureus 2020 Jan 14;12(1):e6649. Epub 2020 Jan 14.

Emergency Medicine, The Permanente Medical Group, Kaiser Permanente, Santa Clara, USA.

Evaluation of undifferentiated pediatric abdominal pain presents a unique set of challenges, especially in the setting of inconclusive and limited diagnostic imaging. In this case report, a female child presented to the emergency department with persistent abdominal pain, normal lab studies, and unusual trans-abdominal pelvic ultrasound findings. Urgent exploratory laparoscopy was completed, demonstrating a torsed adnexa rotated around a very large, mature teratoma, with irregular masses consistent with fully developed teeth. Read More

The eventual successful management of ovarian torsion in a hyperstimulated ovary following in vitro fertilization: A case report.

Case Rep Womens Health 2020 Apr 7;26:e00166. Epub 2019 Dec 7.

Women Directorate, Royal Victoria Infirmary, Newcastle Upon Tyne NE1 4LP, United Kingdom.

Abdominal pain following in vitro fertilization (IVF) in the presence of enlarged ovaries commonly leads to the diagnosis of ovarian hyperstimulation syndrome (OHSS). Progressively worsening pain with a rise in inflammatory markers with normal hematological indices implies a diagnosis of ovarian torsion of the hyperstimulated ovary. Early recourse to laparoscopic assessment and derotation of the affected ovary even after 72 h following the onset of symptoms can allow a return to viability. Read More

Twist and shout: magnetic resonance imaging findings in ovarian torsion.

Radiol Bras 2019 Nov-Dec;52(6):397-402

Instituto de Medicina Integral Professor Fernando Figueira, Recife, PE, Brazil.

Adnexal torsion is characterized by partial or complete rotation of the suspensory ligament of the ovary and its corresponding vascular pedicle, resulting in vascular impairment that can culminate in hemorrhagic infarction, as well as necrosis of the ovary and fallopian tube. Because there are myriad causes of acute pelvic pain, the differential diagnosis of ovarian torsion is often challenging. Consequently, radiologists should be familiar with the main imaging findings.

Extragonadal mature cystic teratoma at anterior uterine wall coexisting with a pararectal corpus luteum cyst and agenesis of left fallopian tube and left ovary.

Taiwan J Obstet Gynecol 2020 Jan;59(1):154-156

Department of Obstetrics and Gynecology, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung, Taiwan; Department of Obstetrics and Gynecology, School of Medicine, Kaohsiung Medical University, Kaohsiung, Taiwan. Electronic address:

Objective: Mature cystic teratomas are mostly confined to the ovaries, but several authors have reported findings of extragonadal occurrences along the migration pathway of primordial germ cells. Extragonadal mature cystic teratomas are extremely rare; their occurrences and pathogenesis are unknown.

Case Report: We report the case of a 26-year-old woman who was admitted for scheduled laparoscopic right ovarian tumor excision. Read More

Sildenafil Citrate: Novel Therapy in the Management of Ovarian Torsion.

J Hum Reprod Sci 2019 Oct-Dec;12(4):351-354. Epub 2019 Dec 17.

Athavale Imaging Centre, Mumbai, Maharashtra, India.

Ovarian torsion is defined as partial or complete rotation of ovarian vascular pedicle, leading to the obstruction of venous outflow and arterial inflow. It is an emergency condition with an incidence of 2%-15% in patients with adnexal masses. The main risk in ovarian torsion is an ovarian mass or an enlarged ovary with a long pedicle. Read More

Imaging in gynecological disease: clinical and ultrasound characteristics of adnexal torsion.

Ultrasound Obstet Gynecol 2020 Jan 24. Epub 2020 Jan 24.

Fondazione Policlinico Universitario Agostino Gemelli, IRCCS, Dipartimento Scienze della Salute della Donna, del Bambino e di Sanità Pubblica, Roma, Italia.

Objective: To describe the clinical and ultrasound characteristics of adnexal torsion.

Methods: This is a retrospective study. From the operative records of the eight participating gynecological ultrasound centers, we identified patients with a surgically confirmed diagnosis of adnexal torsion (surgical evidence of twisted ovarian pedicle and/or twisted paraovarian cyst and/or tube on its own axis), who had undergone preoperative ultrasound examination by an experienced ultrasound examiner between 2008 and 2018.

Ovarian torsion: developing a machine-learned algorithm for diagnosis.

Pediatr Radiol 2020 May 22;50(5):706-714. Epub 2020 Jan 22.

Department of Radiology, Seattle Children's Hospital and the University of Washington, Seattle Children's Hospital, MA.7.220, 4800 Sand Point Way NE, Seattle, WA, 98105, USA.

Background: Ovarian torsion is a common concern in girls presenting to emergency care with pelvic or abdominal pain. The diagnosis is challenging to make accurately and quickly, relying on a combination of physical exam, history and radiologic evaluation. Failure to establish the diagnosis in a timely fashion can result in irreversible ovarian ischemia with implications for future fertility. Read More
