目的：探讨高场磁共振成像（MRI）对卵巢巧克力囊肿的诊断价值。方法回顾性分析经手术病理证实的卵巢巧克力囊肿23例共56个病灶的特点。23例患者中15例行 MRI 平扫加增强扫描，8例仅行 MRI 平扫，16例行 DWI 扫描。23例患者同时均行妇科超声检查。17例患者同时检查糖类抗原199及125（CA199及CA125）检查。结果23例患者术前 MRI 正确诊断21例，诊断准确率为91％（21／23），B 超的诊断准确率为30％（7／23），两者诊断准确率差异有统计学意义（P ＜0．05）。56个病灶中，复杂病灶有5个，51个病灶相对信号均匀。卵巢巧克力囊肿双侧多见，多为多发，以类圆形或类椭圆形多见，典型可见葫芦形，45％（25／56）的病灶最大径为20～50 mm 。 T1WI 像51个病灶中45个为高信号（88．2％）；T2WI 像51个病灶中35个为高／稍高信号（68．6％）。囊壁均匀／不均匀增厚者23个（41％）；可见极低信号沉积在后壁者9个。囊壁周围见“卫星囊”者10个。11例病灶内可见分隔或壁结节。23例患者中17例检查血 CA125，其增高率达88％（15／17），平均值为92μg／mL 。结论卵巢巧克力囊肿 MRI 表现多样，但有其特点，仔细分析 MRI 特征并结合 CA125可以做出准确诊断。 DWI 图及ADC 值的测定对巧克力囊肿的诊断无特异性。
目的：探討高場磁共振成像（MRI）對卵巢巧剋力囊腫的診斷價值。方法迴顧性分析經手術病理證實的卵巢巧剋力囊腫23例共56箇病竈的特點。23例患者中15例行 MRI 平掃加增彊掃描，8例僅行 MRI 平掃，16例行 DWI 掃描。23例患者同時均行婦科超聲檢查。17例患者同時檢查糖類抗原199及125（CA199及CA125）檢查。結果23例患者術前 MRI 正確診斷21例，診斷準確率為91％（21／23），B 超的診斷準確率為30％（7／23），兩者診斷準確率差異有統計學意義（P ＜0．05）。56箇病竈中，複雜病竈有5箇，51箇病竈相對信號均勻。卵巢巧剋力囊腫雙側多見，多為多髮，以類圓形或類橢圓形多見，典型可見葫蘆形，45％（25／56）的病竈最大徑為20～50 mm 。 T1WI 像51箇病竈中45箇為高信號（88．2％）；T2WI 像51箇病竈中35箇為高／稍高信號（68．6％）。囊壁均勻／不均勻增厚者23箇（41％）；可見極低信號沉積在後壁者9箇。囊壁週圍見“衛星囊”者10箇。11例病竈內可見分隔或壁結節。23例患者中17例檢查血 CA125，其增高率達88％（15／17），平均值為92μg／mL 。結論卵巢巧剋力囊腫 MRI 錶現多樣，但有其特點，仔細分析 MRI 特徵併結閤 CA125可以做齣準確診斷。 DWI 圖及ADC 值的測定對巧剋力囊腫的診斷無特異性。

Objective To investigate the value of high‐field magnetic resonance imaging (MRI) for the diag‐nosis of chocolate cyst .Methods Retrospective analysis was conducted for the lesions characteristics in the pathologically confirmed 23 cases of chocolate cyst .Results Preoperative MRI diagnosed 21 cases correctly in 23 cases ,with the diagnosis rate of 91% (21/23) ,B super diagnostic accuracy was 30% (7/23) ,which had significant differences between the diagnostic accuracy ,with (P < 0 .05) .56 lesions were found in 23 cases ,with 5 complex lesions ,with 51 lesions of relatively even signals .Bilateral and multiple lesions are commonly seen in chocolate cyst ,with round or oval class ,and gourd‐shaped were typically visible .45%(25/56) of the lesion were 20 - 50 mm in size .In the 51 lesions by T1WI ,45 had high signals ,accounting for 88 .2% (45/51) ;in 51 lesions by T2WI ,35 had high/slightly higher signals ,accounting for 68 .6% (35/51) .There were 23 lesions with uniform wall/uneven thickening ,accounting for 41% (23/56) ;9 lesions with visibly low signal deposited in the posterior wall .There were 10 lesions with “satellite sac” seen on the wall around .The separated or mural nodules were seen in11 cases of lesions .The blood CA125 of 17 ca‐ses were examined in 23 patients and15 cases were found increased ,with an average of 92 μg/ml .Conclusion MRI manifestation in chocolate cyst takes various forms ,but with its own characteristics .MRI features analysis and CA125 can make an accurate diagnosis in chocolate cyst .DWI and ADC had no value in diagnosis .
