There were clear enhancement and unclear demarcation of uterine and adjacent structures, and unclear imaging of uterine structures (Figure 1).
(a) Abundant mucous gelatinous tissue and ascites are seen in the abdominal cavity along with bilateral giant ovarian cysts of about 25 x 15 x 15 cm and (b) at 8 x 6 x 4 cm mass in the transverse colon that infiltrated and adhered to the abdominal wall.

An 8 x 6 x 4 cm transverse colon mass that had infiltrated and adhered to the abdominal wall, about 2000 mL of mucous gelatinous tumor tissue, ascites, and both ovarian cysts, were completely removed (Figure 2).
Postoperative gross pathology of a transverse colonic mucinous adenocarcinoma after cytoreductive surgery. Immunohistochemical staining of the tumor tissue was CK7(-), CK20(+), CA125(-), CA19-9(+), CDX-2(+), cadherin 17(+), P53(+++), PAX8(-), SATB2(+), beta-catenin(+), and 60% Ki-67(+).

Immunohistochemical staining found that the primary tumor was CK7(-), CK20(+), CA125(-), CA19-9(+), CDX-2(+), cadherin17(+), P53(+++), PAX8(-), SATB2(+), beta-catenin(+), and 60% Ki-67(+) (Figure 3).
