- Long list of potential causes, encompassing tumor (primary and neoplastic), inflammation and infection in a postmenopausal woman
- Potential tumors: serous and mucinous cystadenoma/cystadenocarcinoma, teratoma, clear cell carcinoma, endometrioid carcinoma, necrotic primary or metastatic tumors
- Most of these (if we think it is neoplasm) would need to be diagnosed histologically because imaging findings are nonspecific and malignancy cannot be excluded
- Uncommon ovarian neoplasm, usually incidentally found
- Women in 5th to 7th decade of life
- Predominantly solid, but can be complex with cystic components when associated with serous and mucinous cystadenomas (seen in up to 30% of cases)
- Can be benign, borderline or malignant
