TVS showed a left ovarian unilocular cyst, size 6cm x 5cm x 4cm, with diffuse low-level internal echoes, thin walled, smooth margined, no septa and no papillary projections (Figure 1).
(A) contrast-enhanced CT images show a unilocular cystic lesion (white arrow) abutting the left ovary (black arrowhead) and fallopian tube (white arrowhead); (B) contrast-enhanced CT images show a unilocular cystic lesion (white arrow), uterus (white arrowhead) and myoma (black arrowhead)

Pelvic contrast-enhanced computed tomography (ECT) images revealed a unilocular cystic lesion measuring 6 cm at its widest dimension, without enhancing solid intramural nodules and no evidence of lymphadenopathy or ascites (Figure 2).
(A) polypoid lesion on the internal surface of the paratubal cyst (hematoxylin and eosin stain; original magnification x 20); (B) tumor cells show nuclear atypism and stratification without stromal invasion (hematoxylin & eosin stain; original magnification x 100)

The tumor cells showed nuclear atypism and stratification, which are histological characteristics of borderline tumor (Figure 3).

Multiplanar reconstruction CT imaging revealed linear fat planes between the left ovary and the cyst (Figure 4), indicating that the left ovary, fallopian tube and paratubal cyst were separate structures, similar to those seen during surgery.
