To determine whether there is any correlation between the number of loculi and the pathological grade of malignancy in mucinous cystic tumors of the ovary.
We retrospectively studied MR images of 67 pathologically proven mucinous cystic tumors of the ovaries. Of these 67 cases, 38 were cystadenomas and 29 were malignant lesions (18 borderline malignancy and 11 adenocarcinomas). We counted the number of loculi and measured the maximum diameter of masses on MRI. We compared the number, the maximum diameter, and the ratio of the number of loculi to the maximum diameter in each adenoma and malignancy using Student's t-test.
The mean number of loculi was 18.2 in cystadenoma and 80.9 in malignant lesions. The mean maximum diameter of tumors was 13.0 cm in cystadenoma and 18.7 cm in malignant lesions. The mean ratio of the number of loculi to the maximum diameter was 1.3 in adenoma and 5.4 in malignant lesions. The differences between the benign and malignant lesions were statistically significant in number (P = 0.001), maximum diameter (P = 0.011), and ratio (P = 0.002).
Ovarian mucinous neoplasm of borderline malignancy and mucinous adenocarcinomas had a larger number of loculi than adenomas.
确定卵巢黏液性囊性肿瘤的分隔数量与恶性病理分级之间是否存在相关性。
我们回顾性研究了67例经病理证实的卵巢黏液性囊性肿瘤的磁共振成像（MR）图像。这67例病例中，38例为囊腺瘤，29例为恶性病变（18例交界性恶性肿瘤和11例腺癌）。我们在磁共振成像上计数分隔数量并测量肿块的最大直径。我们使用学生t检验比较了每个腺瘤和恶性肿瘤的分隔数量、最大直径以及分隔数量与最大直径的比值。
囊腺瘤的平均分隔数量为18.2个，恶性病变为80.9个。囊腺瘤的肿瘤平均最大直径为13.0厘米，恶性病变为18.7厘米。腺瘤中分隔数量与最大直径的平均比值为1.3，恶性病变为5.4。良性和恶性病变在数量（P = 0.001）、最大直径（P = 0.011）和比值（P = 0.002）方面的差异具有统计学意义。
交界性恶性卵巢黏液性肿瘤和黏液腺癌的分隔数量比腺瘤更多。
