ABSTRACT
Mastitis is a benign inflammatory breast disease that can mimic breast carcinoma clinically and radiologically and has a tendency to recur. The aim of radiology is to characterize the inflammatory state with imaging methods and, if necessary, percutaneous interventional procedures and to contribute to treatment with therapeutic interventional methods. The first thing to do is to distinguish between malignant and non-malignant inflammation. Therefore, pathological confirmation is often required. Fine needle aspiration biopsy, core biopsy, and vacuum-assisted biopsy can be performed for histopathological diagnosis. Along with medical treatment, the use of drainage methods and intralesional steroid injections depending on the condition of the lesion and the patient can accelerate the recovery period and reduce the recurrence. Response to treatment should be monitored by ultrasonography. Follow-up with magnetic resonance imaging is required in patients who are diffuse, aggressive, and unresponsive to treatment.
