Objective:

To detect the characteristics of ultrasonography and MRI of ovarian serous surface papillary borderline tumor (SSPBT)

and to evaluate the value of ultrasonography and MRI in the diagnosis of SSPBT.

Methods:

8 women with SSPBT from Obstetrics and Gynecology Hospital

Fudan University during 2010 and 2013 were retrospectively analyzed

and their clinical information and characteristics of ultrasonography and MRI were compared with operation and pathology.

Results:

Of the 8 women

the median age was (30.35.3) years old (range 25-44). Carbohydrate antigen 125 (CA125) was elevated in 7 cases (87.5%)

and CA19-9 in 2 cases. The level of carcinoembryonic antigen (CEA) was normal in all patients. With respect to the pathology

5 cases had SSPBT in both ovaries

2 cases had SSPBT in one ovary and serous cystic tumor of borderline malignancy in the contralateral ovary

and 1 case had SSPBT in one ovary and serous cystadenoma in the contralateral ovary. The ovaries involved were usually covered by neoplasm-like cauliflower

papilla or millet

and some manifested cystic ovaries or hyperblastosis. Preoperative ultrasonography showed unilateral or bilateral masses in all patients. Ovarian tissue was detected beside or in the masses in 5 SSPBTS (38.5%

5/13). The boundary of the ovary was not clear in 1 mass. 2 masses were miss-diagnosed. The median diameter of the masses was (96.122.7) mm. Most masses displayed medium or low or mixed echo in ultrasound and blood flow was detected with Doppler ultrasound in 6 masses. MRI suggested that the cystic or solid masses were the main form. The cystic part of the mass showed hypointensity or slight hyperintensity on T1WI and hyperintensity on T2WI. The solid component showed isointensity on T1WI and isointensity/hyperintensity on T2WI. With contrast agent

the solid component but not cystic component showed obvious enhancement.

Conclusion:

Most patients with SSPBT are in child-bearing period and both ovaries are usually involved. Ultrasonography may have more advantages than MRI in the diagnosis of SSPBT in early stage.
