Paraovarian cyst

Pathophysiology

PTCs originate from the mesothelium and are presumed to be remnants of the Müllerian duct and Wolffian duct.

Diagnosis

Most cysts are small and asymptomatic. Large cysts can lead to torsion of the adnexa inflicting acute pain.

Prior to surgery, PTCs are usually seen on ultrasonography. However, because of the proximity of the ovary that may display follicle cysts, it may be a challenge to identify a cyst as paratubal or paraovarian.

Malignancy

PTCs are generally benign, but may, on rare occasions, give rise to borderline tumors and malignancies.

Management

Smaller lesions can be followed expectantly. Larger lesions, lesions that are growing or symptomatic, and lesions with sonographically suspicious findings (septation, papillations, fluid and solid components) are generally surgically explored and removed.

Epidemiology

PTCs have been reported in all female age groups and seem to be most common in the third to fifth decades of life. A study in Italy estimated their incidence to be about 3%, These cysts constitute about 10% of adnexal masses.

Hydatid cysts of Morgagni

Hydatid cysts of Morgagni, also hydatids of Morgagni or Morgagni's cysts, are common and appear as pedunculated, often tiny, frequently multiple cysts connected to the fimbriae of the fallopian tubes. They thus appear to be a specific variant of paratubal cysts. They are named after Giovanni Battista Morgagni.

While usually asymptomatic, it has been noted that these cysts tend to be more common in women with unexplained infertility (52.1% versus 25.6% in controls, p
