Objective: To retrospectively analyze the clinical records and imaging data of patients with diabetic mastopathy according to pathological findings of samples obtained by histological puncture with ultrasound guidance. Methods: Between 2002 and 2007, six patients were diagnosed with diabetic mastopathy, and their medical records and MR images were assessed. All patients underwent both mammography and ultrasound examination. One of them was additionally submitted to MRI. Results: The patients' mean age was 36.6 years. Mammograms showed asymmetric tissue densifications without micro calcifications, while ultrasound examination evidenced ill-defined solid nodular or pseudonodular areas greater than 2 cm, with posterior sonic attenuation. Magnetic resonance imaging revealed a nodular area with poorly defined contours with enhancement similar to normal breast tissue. By performing eco-guided biopsy, it was possible to establish the differential histological diagnosis of breast carcinoma and to confirm diabetic mastopathy. Conclusion: Diabetic mastopathy presents mammographic and ultrasound imaging features indistinguishable from breast cancer. Since MRI does not reveal pathological stromal enhancement it can be helpful for a differential diagnosis. The echo-guided biopsy allows the diagnosis of this condition.
