[Ultrasonographic features of primary non-Hodgkin's breast lymphoma].
OBJECTIVE
To summarize the sonographic features of primary non-Hodgkins lymphoma of the breast using the Breast Imaging Reporting and Data System-Ultrasound (BI-RADS-US) and explore the value of ultrasonography in the preoperative diagnosis.


METHODS
The clinical data of 11 patients with primary non-Hodgkins lymphoma of the breast were retrospectively reviewed. BI-RADS-US grading was performed for each lesion.


RESULTS
Totally 13 lesions were detected in 11 patients. Single lesion at one side was detected in 9 patients (81.8%). Circumscribed (n=7, 53.8%) or microlobulated lesions (n=5, 38.5%), parallel orientation (n=10, 76.9%), and oval masses (n=8, 61.5%) were also observed on sonography. The echo pattern of the mass was hypoechoic in 10 lesions (76.9%), hyperechoic in 1 lesion, and complex echoic in 2 lesions. No mass had speculated margins or calcifications. Ipsilateral axillary lymph node involvements were noted in 6 patients.


CONCLUSIONS
Most primary non-Hodgkins lymphomas of the breast present as single hypoechoic masses with circumscribed or microlobulated margins and parallel orientation on sonography. BI-RADS-US, combined with the analyses of multiple signs, is feasible for the pre-surgical diagnosis.
