follicular cyst
immature teratoma
granulosa cell tumor
polycystic ovarian disease
serous cystadenocarcinoma

Explanation:

1. Analyze each option:

• Follicular cyst: Benign, common in reproductive years, not associated with large masses and ascites in a 52 - year - old.
• Immature teratoma: Rare, more common in younger patients, and not typically associated with ascites in this context.
• Granulosa cell tumor: Can present with hormonal symptoms, but ascites with a large mass in a 52 - year - old is less typical for this tumor.
• Polycystic ovarian disease: Affects younger women, presents with multiple small cysts, not a large mass and ascites.
• Serous cystadenocarcinoma: Ovarian cancer, common in post - menopausal women (52 - year - old is post - menopausal), often presents with a large ovarian mass and ascites due to peritoneal spread.

Answer:

E. serous cystadenocarcinoma
