摘要

目的：

探讨交界性上皮性卵巢肿瘤(borderline epithelial ovarian tumor，BEOT)的常规MRI表现，明确MRI鉴别BEOT与恶性上皮性卵巢肿瘤(malignant epithelial ovarian tumor，MEOT)的价值。

方法：

回顾性分析经手术和病理证实的67例BEOT患者的临床及MRI资料，观察肿瘤双侧性、大小、形态、边界、囊实性分界、构型、乳头或结节、信号、强化程度、同侧卵巢显示、腹膜种植灶及腹腔积液，并与69例MEOT的征象比较。

结果：

67例BEOT共86个肿瘤，平均大小(13.06.7) cm，其中19例(28%)累及双侧卵巢；69例MEOT共98个病灶，平均大小(9.34.2) cm，其中29例(42%)累及双侧卵巢。两组肿瘤大小和双侧性差异无统计学意义(

=0.864，

=0.095)。两组肿瘤在形态、边界和囊实性分界方面差异有显著统计学意义(

均＜0.001)。BEOT多呈(类)圆形、边界和囊实性分界清；而MEOT多呈分叶或不规则，边界和囊实性分界不清。纯囊性[9/86 (10%)

结论：

MRI可显示BEOT和MEOT不同的征象，有助于两者鉴别。

Abstract

Objective:

To investigate MRI features of borderline epithelial ovarian tumors (BEOTs) and to differentiate BEOT from malignant epithelial ovarian tumors (MEOTs).

Methods:

The clinical and MRI data of 67 patients with

BEOT and 69 patients with MEOT proven by surgery and pathology were reviewed retrospectively. MRI features including bilaterality

size

shape

margin

cystic-solid interface

configuration

papilla or nodule

signal

enhancement

presence of ipsilateral ovary

peritoneal implants and ascite were analyzed.

Results:

There were 67 BEOT patients with 86 tumors [mean size of (13.06.7) cm

]

and bilateral ovaries were involved in 19 cases. There were 69 MEOT patients with 98 tumors [(9.34.2) cm

]

and bilateral ovaries were involved in 29 cases. There were no significant differences in size and bilaterality between the two groups. There were significant differences in shape

margin and clear cystic-solid interface (all

0.00 1) between the two groups. BEOT frequently presented as round or oval shape

clear margin and cystic-solid interface. In contrast

MEOT often demonstrated the lobulated or irregular shape

unclear margin and unclear cystic-solid interface. Purely cystic papilla or nodules [9/86 (10%)

. 1/98 (1%)

]

predominantly cystic papilla or nodules [31/86 (36%)

. 11/98 (11%)

0.001

]

exophytic papilla or nodules [23/86 (27%)

. 7/98 (7%)

0.001

]

branching papilla [28/86 (33%)

. 0/98 (0%)

0.001

]

and presence of ipsilateral ovary [29/86 (34%)

. 0/98 (0%)

0.001

]

were found more frequently in BEOT than in MEOT. The combination of these five features yielded a sensitivity

specificity and accuracy of 84%

81% and 82%.

Conclusion:

MRI can manifest different morphological features between BEOT and MEOT

and help todistinguish BEOT from MEOT.
