卵巢平滑肌瘤是一种罕见的良性肿瘤，多见于20-65岁的女性。报告1例51岁女性盆腔大肿瘤。肿瘤的主要特征是囊性成分，但沿肿瘤背缘可见不规则的实性成分。后者在T2加权像上表现为与肌肉一样低的信号强度和明显的对比度增强，但未显示限制性扩散，提示为良性病变。由于不能排除恶性，大肿瘤被切除，病理诊断为以坏死为主的卵巢平滑肌瘤。当在磁共振成像上看到没有恶性特征的低信号成分时，尽管子宫肌瘤很少发生在卵巢，但仍应包括在鉴别诊断中。
Ovarian leiomyoma is a rare benign tumor, seen mostly in women 20-65 years old. The case of a 51-year-old woman with a large tumor in the pelvic cavity is reported. The dominant feature of the tumor was its cystic component, but an irregular, solid component was recognized along the dorsal margin of the tumor. The latter area showed signal intensity as low as muscle on T2-weighted images and significant contrast enhancement; however, it did not show restricted diffusion, which implied that it was benign. The large tumor was resected because malignancy could not be ruled out, and it was pathologically diagnosed as ovarian leiomyoma with predominant necrosis. When a low-intensity component without malignant features is seen on magnetic resonance imaging, leiomyoma should be included in the differential diagnosis despite its rare occurrence in the ovary.
