Surgically transposed ovary presenting as an intraperitoneal mass on computed tomography

Area of Science:

• Reproductive medicine
• Surgical oncology
• Diagnostic imaging

Background:

• Surgical transposition of ovaries is a rare procedure, often performed for fertility preservation or to manage ovarian torsion.
• The typical anatomical location of the ovary is within the pelvic cavity, suspended by its mesovarium.
• Variations in ovarian presentation on imaging can pose diagnostic challenges.

Observation:

• A case of left ovarian transposition is presented, where the ovary was visualized as an intraperitoneal cystic mass on computed tomography (CT).
• This imaging finding is unusual, as transposed ovaries typically maintain a retroperitoneal position.
• The mass demonstrated characteristics consistent with ovarian tissue, despite its atypical location.

Findings:

• Computed tomography (CT) revealed a cystic mass in the intraperitoneal space, later identified as a surgically transposed left ovary.
• This presentation differs significantly from the only previously reported case of a transposed ovary on CT, which appeared as a retroperitoneal mass.
• The case highlights the potential for significant anatomical displacement and varied imaging appearances following ovarian transposition surgery.

Implications:

• This case expands the understanding of the computed tomography (CT) appearance of surgically transposed ovaries.
• Radiologists and surgeons should consider ovarian transposition when encountering atypical adnexal masses, particularly in patients with a relevant surgical history.
• Accurate identification of transposed ovarian tissue is crucial for appropriate clinical management and to avoid misdiagnosis.
