“…Clinically, it is difficult to distinguish between primary and metastatic cancer of the ovary, which results in diagnostic problems for clinicians, radiologists and pathologists. Regarding radiological examination, Cho and Gold (12) reported that a mixed cystic and solid ovarian mass observed by CT scan must be regarded as a metastatic tumor in patients with a history of colonic or gastric carcinoma. In the present cases, the ovarian tumor presented as a multilocular cystic pelvic mass with a solid component.…”

Abstract. Ovarian metastasis of colorectal cancer is relatively rare. The present study reports two cases of synchronous ovarian metastasis from colorectal cancer, which were managed by cytoreductive surgery. In case one, a 60-year-old female patient presented with a multilocular pelvic tumor and ascites. Virtual colonoscopy revealed a mass in the sigmoid colon; however, no tumor cells were identified on histological examination. Ovarian metastasis from sigmoid colon cancer was suspected and adnexectomy was subsequently performed. Histological examination of the excised tumor revealed adenocarcinoma. Immunohistochemical analysis of the resected tumor revealed positive staining for cytokeratin (CK)20 and caudal-type homeobox 2 (CDX2), and negative staining for CK7, estrogen receptor, progesterone receptor and inhibin. The immunohistological results supported the diagnosis of ovarian metastasis from sigmoid colon cancer. In case two, a 56-year-old female patient presented with a multilocular pelvic tumor and ascites. Colonoscopy identified a rectal tumor, and histological examination revealed moderately-differentiated adenocarcinoma, which was confirmed by cytological analysis of ascites. Subsequently, ovarian metastasis from rectal cancer with peritoneal dissemination was diagnosed, and left ovariectomy and transverse colostomy were performed. Histological examination of the excised tumor revealed moderately-differentiated adenocarcinoma, and immunohistochemical investigation revealed positive staining for CK20 and CDX2, but negative staining for CK7. These immunohistological results indicated ovarian metastasis from rectal cancer. Both patients recovered well and are currently undergoing regular follow-up examinations. The observations from the two cases indicate that ovarian metastases of primary colorectal cancer may present as pelvic tumors and, thus, preoperative examination of the gastrointestinal tract is required. Furthermore, even in cases of widespread colorectal cancer metastases, excision of the ovarian tumor is required to establish a histological diagnosis for the selection of appropriate treatments. IntroductionCommon sites for synchronous metastases from colorectal cancer include the liver, lung, peritoneum, bone and brain (1). The frequency of ovarian metastasis from colorectal cancer is 1.6-6.4%, however, this type of metastasis is difficult to distinguish from primary ovarian neoplasms (2-5). Furthermore, synchronous ovarian metastasis from colorectal cancer is generally poor, and the optimal first-line treatment strategy is debatable (6,7). The present study reports two cases of synchronous ovarian metastasis from colorectal cancer that were managed by cytoreductive surgery. Case reportCase one. A 60-year-old female patient presented to Katsuta Hospital (Katsuta, Japan) in June 2014 with progressive abdominal distension and lower abdominal pain. The following day the patient was referred to Ibaraki Medical Center, Tokyo Medical University (Ami, Japan) with a suspected diagnosis of pelvic tumor...

“…However, the solid part of Krukenberg also shows conspicuous enhancement on MRI [ 5 ]. It could be diffi cult to differentiate primary ovarian malignancy from Krukenberg tumors by imaging fi ndings of ovarian tumors alone [ 10 ]. The identifi cation of other malignant tumors on CT or MRI, especially of the colon and stomach, provides supportive evidence of Krukenberg tumors [ 10 ].…”

“…14). 9 Pseudomyxoma peritonei Pseudomyxoma peritonei is characterized by the slow accumulation of large volumes of mucinous ascites in the peritoneal cavity from the rupture of mucinous tumour of the ovary or appendix. Pseudomyxoma peritonei appears as low-density cystic deposits, which exert mass effect and cause scalloping of the liver surface or prevent bowel loops from floating to the anterior abdominal wall (Fig.…”

The peritoneal cavity is a potential space that is divided by the peritoneal reflections into various complex subspaces. It can be involved in many disease processes including developmental, inflammatory, neoplastic and traumatic conditions. Computed tomography is highly sensitive and consistent in detecting peritoneal pathology. This pictorial essay aims to emphasize and illustrate the CT features of the spectrum of peritoneal diseases.
