Overview
MRI is the most specific in the diagnosis of mastitis.[1] On contrast-enhanced MRI, most non-puerperal mastitis are characterized by non-mass-like lesion with heterogeneous signal intensity. Rim or rim-like enhancement on contrast-enhanced MRI with central hypointensity areas showing as hyperintensity on T2-weighted imaging is suggestive of the possibility of non-puerperal mastitis.[2]
MRI
On contrast-enhanced MRI, most non-puerperal mastitis are characterized by non-mass-like lesion with heterogeneous signal intensity. The observation of rim or rim-like enhancement on contrast-enhanced MRI with central hypointensity areas showing as hyperintensity on T2-weighted imaging is suggestive of the possibility of non-puerperal mastitis.[2]
On MRI, most patients with granulomatous mastitis are characterized by segmental T2 hyperintensity with contrast-enhancement on T1,[3] however, enhancing T2 hypointense mass with irregular margin was present in minority of patients with granulomatous mastitis.[3][4] Among the available radiological modalities, MRI is the most specific in the diagnosis of mastitis.[1]
