Fig. 29 Typical bilateral Krukenberg tumors in a patient with history of gastric cancer. Coronal (a) and transaxial (b) CT show bilateral ovarian tumors with central
necrosis. On the left ovary, a transversing vessel can be identified in b (arrows). U uterus
in the absence of extensive peritoneal spread is unusual for ovarian cancer and favors another primary neoplasm (Young and Scully 2002b).
Differential Diagnosis
Confident distinction between primary and metastatic ovarian cancers is not feasible due to overlapping imaging findings. Bilateral, well-delineated, purely solid or predominantly solid tumors with necrosis strongly favor the diagnosis of Krukenberg tumors (Alcazar et al. 2003). Multinodularity at the ovarian surface is also a feature suggesting ovarian metastases, but this may also be seen in dysgerminomas and lymphomas (Horta and Cunha 2015; Li et al. 2012). Contrast uptake aids in the differentiation of solid ovarian metastases from stromal tumors. Stromal tumors typically display a mild and delayed contrast uptake resp type 1 time-intensity curves. If such a solid lesion shows low signal on a high b value DWI, the presence of metastases can be excluded (Thomassin-Naggara et al. 2009). If
metastases are cystic and hemorrhagic, they may resemble endometriomas, which also occur in younger women. However, enhancing nodules and distinct contrast enhancement is not found in endometriomas. Abscesses usually present with different clinical features than the clinically silent metastases. Similar to sex-cord stromal tumors, ovarian metastases can produce estrogens or androgens. The clinical background is usually different, and history of a primary cancer prone to spread to the ovaries allows the correct diagnosis. Coexistence of a type II endometrial cancer or premenopausal age favor the presence of metastases to the ovaries rather than an independent ovarian cancer (Holschneider et al. 2005).
7.5\ Fallopian Tube Cancer
Fallopian tube cancer has been thought to be extremely rare accounting for only 0.3–1.1% of all gynecologic cancers (Chen and Berek 2016).
