OBJECTIVE To evaluate the diagnostic value of ultrasonography and mammography for plasma cell mastitis. METHODS The ultrasonographic and mammographic images of 111 women with histopathologically confirmed plasma cell mastitis were retrospectively analyzed. The diagnostic accuracy of the two imaging methods was compared. RESULTS Ultrasonography identified 91 out of 111 (82.0%) patients with plasma cell mastitis, while the other twenty (18.0%) patients were misdiagnosed. Mammography identified 83 (74.8%) out of 111 patients with plasma cell mastitis. Nineteen (17.1%) patients were misdiagnosed. There was no significant difference between the diagnostic accuracy of using two imaging tests (P = 0.127). Mammography clouds identified 11 out of 20 patients who were not diagnosed by ultrasonography. Meanwhile, 19 of the 28 cases misdiagnosed with mammography were correctly identified by ultrasonography. Overall, 91.9% (102/111) of the patients were identified by the combination of ultrasonography and mammography, which yielded statistically significant higher accuracy than using each single test only (P < 0.05). CONCLUSIONS In diagnosis of plasma cell mastitis, high-frequency ultrasonography and mammography should be combined to improve the diagnostic accuracy.

结合超声和乳房X线照相术提高浆细胞性乳腺炎的诊断准确性。

目的评价超声和乳房X线照相术对浆细胞性乳腺炎的诊断价值。方法回顾性分析111例经组织病理学证实的浆细胞性乳腺炎女性的超声和乳房X线照片。比较了两种成像方法的诊断准确性。结果 超声检查确定了 111 名 (82.0%) 浆细胞乳腺炎患者中的 91 名，而其他 20 名 (18.0%) 患者被误诊。在 111 名浆细胞性乳腺炎患者中，乳房 X 光检查确定了 83 名 (74.8%)。19 名（17.1%）患者被误诊。使用两种影像学检查的诊断准确性没有显着差异（P = 0.127）。乳房 X 光检查云确定了 20 名未通过超声检查诊断的患者中的 11 名。同时，28例乳房X线检查误诊的病例中，有19例被超声正确识别。总体而言，91.9% (102/111) 的患者通过超声检查和乳房 X 线照相术的组合进行识别，与仅使用单个测试相比，这产生了统计学上显着更高的准确度（P < 0.05）。结论浆细胞性乳腺炎的诊断应结合高频超声和乳腺钼靶检查，以提高诊断的准确性。
