Despite high rates of partial ablation, percutaneous image-guided cryoablation appears to be safe and effective for local control for patients with inoperable extra-abdominal desmoid tumors.
Nipple discharge is a common symptom in breast medicine. It is usually benign in origin (papillomas and galactophore duct ectasia) although it is essential not to miss the risk of an underlying malignant lesion (5%) mostly due to in situ carcinomas. Clinical examination is essential in the management, distinguishing benign "physiological" discharge from discharge suspected of being "pathological" in which further investigations with mammography and ultrasound are required. When the conventional imaging assessment for pathological nipple discharge is normal, breast MRI is gradually replacing galactography although this is still an emerging and invalidated indication. In this context and if the whole imaging assessment is normal, surgery is no longer the only solution for patients, who can now be offered regular monitoring.
The histological type of tumour according to the WHO: ductal, lobular, rare forms, is correlated with specific aspects of the imaging based on each type. This morphological classification was improved by knowledge of the molecular anomalies of breast cancers, resulting in the definition of cancer sub-groups with distinct prognoses and different responses to treatment: luminal A, luminal B, HER2 positive, basal-like, triple-negative. Studies are beginning to deal with the appearance of each sub-type in the imaging. It is now important for the radiologist to be familiar with them.
The new molecular classification of breast cancers defines cancer sub-groups with a distinct prognosis and response to treatment. Studies on the literature deal with the imaging of each tumour sub-type. The radiologist should be familiar with them in order to adapt the care of an aggressive sub-type. In view of the current knowledge, the following have been significantly more often observed: mammographical spiculated mass with echogenic halo in luminal A sub-type; architectural distortion in luminal B sub-type; an irregular mass with indistinct margin comprising microcalcifications, with an abrupt interface in the sonography, or non-sonographic mass in the HER2 sub-type; a very hypoechogenic, lobulated mass with indistinct or microlobulated margin, with an abrupt interface, sometimes pseudo-benign, in the triple-negative sub-type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
