Granulomatous lobular mastitis: imaging, diagnosis, and treatment.

Objective: Granulomatous lobular mastitis is a rare chronic inflammatory disease that has clinical and radiologic findings similar to those of breast cancer. We performed a retrospective analysis of clinical, imaging, and treatment findings in 54 women diagnosed with granulomatous lobular mastitis between January 2000 and April 2008.

Conclusion: The imaging findings of granulomatous lobular mastitis overlap with those of malignancy.
