Herein, we report magnetic resonance imaging (MRI) findings of a mucinous borderline tumor of the ovary, which we observed as a mainly solid tumor with large solid components in the lower pelvic cavity. The appearance of ovarian epithelial tumors on imaging is often complex. Cystic to solid appearing masses may be observed, and they often resemble epithelial carcinoma. Due to mucinous or hemorrhage components of packed small or microcystic components, MRI depicts slightly high signal intensity on T1-weighted images and low signal intensity on T2-weighted images. Mucinous borderline tumor of the ovary with a large solid component is very rare, but it is clinically important to recognize the possibility of mucinous borderline tumor to avoid unnecessary surgical intervention.
在此，我们报告一例卵巢黏液性交界性肿瘤的磁共振成像（MRI）表现，我们观察到该肿瘤为盆腔下部的一个主要为实性的肿瘤，具有大的实性成分。卵巢上皮性肿瘤在影像学上的表现通常较为复杂。可观察到呈囊实性的肿块，且常类似上皮癌。由于密集的小囊或微囊成分中的黏液或出血成分，MRI在T1加权图像上显示为稍高信号强度，在T2加权图像上显示为低信号强度。具有大实性成分的卵巢黏液性交界性肿瘤非常罕见，但认识到黏液性交界性肿瘤的可能性以避免不必要的手术干预在临床上很重要。
