To characterize imaging findings that suggest the benign or malignant histologic nature of phyllodes tumors.
Clinical and imaging findings were retrospectively reviewed in 46 women with 51 phyllodes tumors (32 benign, 19 malignant) identified at preoperative mammography. Thirty of these tumors were also evaluated with preoperative sonography.
Mammography showed nonspiculated soft-tissue masses in 49 tumors. Four masses contained calcifications; three of these masses were benign. The tumors were 1-20 cm in diameter; tumors 3 cm or larger were statistically significantly more likely to be malignant (P < .004). Sonography showed solid, hypoechoic masses in 28 cases. At sonography, cystic areas were more often seen in malignant than in benign tumors, but the difference was not statistically significant.
There is substantial overlap in the imaging characteristics of benign and malignant phyllodes tumors. A tumor diameter of 3 cm or greater appears to be associated with a higher likelihood of malignancy.
描述提示叶状肿瘤组织学良性或恶性性质的影像学表现。
回顾性分析46例女性患者的51个叶状肿瘤（32个良性，19个恶性）的临床及影像学表现，这些肿瘤均在术前乳腺钼靶检查中被发现。其中30个肿瘤还进行了术前超声检查。
乳腺钼靶检查显示49个肿瘤为无毛刺的软组织肿块。4个肿块含有钙化；其中3个肿块为良性。肿瘤直径为1 - 20厘米；直径3厘米或更大的肿瘤在统计学上更有可能是恶性的（P <.004）。超声检查显示28例为实性、低回声肿块。在超声检查中，恶性肿瘤比良性肿瘤更常出现囊性区域，但差异无统计学意义。
良性和恶性叶状肿瘤的影像学特征有很大重叠。直径3厘米或更大的肿瘤似乎与更高的恶性可能性相关。
