Idiopathic granulomatous mastitis: imaging update and review
Conclusion
IGM is a rapidly progressive rare inflammatory condition of the breast resulting in non-necrotizing granuloma formation. Imaging features mimic breast carcinoma and diagnosis can be difficult. Radiologists’ awareness of this condition is essential to prevent delayed or unnecessary treatment.
Teaching points
• Idiopathic granulomatous mastitis is rapidly progressive inflammatory condition.
• Imaging features may mimic breast carcinoma or infection.
• Ultrasound shows irregular hypoechoic masses with increased vascularity and sinus tracts.
• MRI shows irregular, enhancing masses or non-mass enhancement with microabscesses.
• MRI is useful for assessment of breast involvement and response to treatment.
