Findings of preoperative pelvic X-ray and computed tomography. Pelvic X-ray (a) and contrast-enhanced computed tomography (b) demonstrated an irregular mass with calcification in the pelvic cavity, measuring approximately 3 cm x 4 cm in diameter. The tumor was not cystic and its margins were not continuous

The lesion was approximately 4 cm in diameter and had calcifications [Figure 1a]. The tumor was not cystic, and its margins were not continuous [Figure 1b].
Findings of laparoscopic surgery. Laparoscopy revealed that the tumor was located in the center of the pelvic cavity (a). The left ovary was lacking, although the left salpinx was normal in shape and location (yellow arrow in a). The right adnexa was normal in position and shape (blue arrow in a). There was a long narrow string connecting the tumor and the left salpinx (yellow arrow in b). The sigmoid colon is indicated by * in (b and c). The tumor was adherent to the surface of the sigmoid colon (c), with a discontinuous capsular shell, calcification and an empty cavity (d). The tumor on the sigmoid colon was resected and the serosal defect in the sigmoid colon was repaired with sutures (e and f)

During laparoscopy, the tumor was located in the center of the pelvic cavity and adherent to the surface of the sigmoid colon with a discontinuous shell and empty cavity [Figures 2a-d and 3a]. The left ovary was lacking, but the left salpinx and right adnexa were normally shaped and positioned [Figure 2a]. There was a long narrow string connecting the left salpinx to the tumor [Figure 2b]. The serosa of the sigmoid colon was cut along the margin of the tumor [Figure 2e]. Next, the serosal defect of the sigmoid colon was repaired with sutures [Figure 2f].
Histopathological findings. Resected tumor with a discontinuous shell and empty cavity (a). Postoperative histopathological examination revealed that the tumor was old fibroma with calcification surrounded by degenerated, anuclear, spindle-shaped cells with a ghost-like appearance (b and c)
