Aims and objectives
Breast lesions are histologically classified as B1 (B1-lesions) when the specimen is composed of normal breast tissue,
with or without parenchymal breast structures,
or when the sample is inadequate for diagnostic evaluation [1,
2].
In both cases,
the management of these lesions is challenging for the radiologist: biopsied lesions have variable but always-significant degree of suspicion,
based on different clinical and imaging features,
that are well-coded [3].
The underestimation rates of biopsies performed under ultrasound [4,
5,
6],
stereotactic [7],
and MR guidance [8] are well known.
Moreover,
the prevalence of cancer in case of imaging-histology discordance and the consequent indication to surgical excision have been assessed [9,
10].
However,
there are only few studies [11] assessing the features associated with malignancy in B1-lesions.
Such an information is clinically relevant in order to appropriately manage them.
Therefore,
the aim of our study is to assess the features associated with malignancy of B1-lesions after percutaneous biopsy.
