Ovarian serous cystadenoma is a non-cancerous type of tumor of the ovary.

[1] It is typically larger than 1cm in diameter and presents with signs and symptoms of a growth in the pelvis, or is discovered when investigating something else.

Diagnostic Procedures includes initially ultrasound or colour doppler study to know about size and nature of mass and sometimes CECT.

Serous cystadenomas are diagnosed by histomorphologic examination, by pathologists.

Grossly, they are, usually, small unilocular cysts that contain clear, straw-coloured fluid.
