IMNs are common on imaging after mastectomy and tissue-expander placement. The IMNs decreased or remained stable on follow-up imaging and may represent reactive nodes

Of 121 patients who underwent axillary ultrasound and CB no malignancy was identified in 73, all of whom subsequently underwent SLNB. Histological evidence of CB in the SLN was identified in 47 (64%) patients. The position of all the lymph nodes identified on ultrasound and the 47 patients whose SLNs were identified were drawn on composite diagrams of the axilla.

Of the 36 nodes identified as sentinel whose position relative to other nodes could be determined, 29 (81%) represented the lowest node identified in the axilla, four (11%) were the second lowest, and three (8%) were the third lowest node. None of the four patients whose CB was from the fourth lowest node had the CB site identified at subsequent SLNB

Ultrasound of the axilla should be carried out in a systematic fashion focusing on level I nodes paying particular attention to the lowest one or two lymph nodes

Nine women with breast cancer, seven with phyllodes, and six with papillomas were found.

No delayed diagnoses in those who had ultrasound would have been made if the following criteria had been applied to avoid needle sampling:

• age less than 25 years
• no known risk factors for breast malignancy
• mass not rapidly enlarging
• smooth discrete mobile mass on clinical examination, or lesion impalpable
• well-defined homogeneously isoechoic or mildly hypoechoic solid mass
• less than 3 cm in greatest dimension
• ovoid shape, aligned parallel to the skin surface
• smooth or gently lobulated contour (two or three lobulations only; no microlobulation
• thin echogenic pseudocapsule
• no calcification
• no acoustic shadowing

Needle sampling could have been safely avoided in approximately two-thirds of the women reviewed below the age of 25 with a solid breast mass

Lesion size has a strong influence on the radiological features of calcific DCIS; small, high-grade lesions often show no casting calcifications, whereas casting calcifications are seen in nearly half of large, low-grade lesions. As small clusters of punctate or granular calcifications may represent high-grade DCIS, an aggressive clinical approach to the diagnosis of such lesions is recommended as the adequate treatment of high-grade DCIS will prevent the occurrence of potentially life-threatening high-grade invasive disease

In patients with breasts injected with foreign material, MRI was used to successfully diagnose malignant breast lesions and could be the diagnostic method of choice. Analysis of the morphological and kinetic features at MRI in conjunction with clinical findings is essential.

Although there are emerging patterns associated with PASH on imaging, the features are not sufficiently specific to allow for a prospective diagnosis. Histological confirmation, preferably with core biopsy, should always be considered

From a BIRADS point of view, on ultrasound these most commonly present as a circumscribed oval solid mass, and therefore benign appearances. The mammographic features are usually more suspicious and therefore more likely to prompt biopsy
