"Secondary tumours of the ovary account for 10–25% of all ovarian malignancies 14. The relative frequency of primary sources depends on the population studied and the study methodology, e.g. surgical versus autopsy series. Gastric cancer incidence is high in Japan and Korea, whereas colorectal and endometrial cancers are more common in Western countries."
"endometrium — the most common gynaecological primary; frequently the most common overall in Western surgical series"
"contralateral ovary — direct or transcoelomic spread; often difficult to differentiate metastasis from synchronous primary"
"fallopian tube — increasingly recognised, particularly high-grade serous carcinoma"
"cervix — less common but well-documented; often squamous cell carcinoma or adenocarcinoma"
"T1: iso to hypointense with variable enhancement on contrast"
"T2: heterogenous signal of the solid component with hyperintensity of the cystic component"
"T2: heterogenous signal of the solid component with hyperintensity of the cystic component"
"There is often a known primary at presentation. Patients may present with abdominal symptoms such as pain or palpable pelvic mass. Hormonal overactivity can also be occasionally seen due to hyperplasia of ovarian stroma."
"They usually spread by a haematogenous route, lymphatic route, or by direct spread. There are usually surface deposits of tumours with invasion of the stroma."
