From: Unilateral primary breast edema: Can T2-weighted images meet the diagnostic challenge?
A 35-year-old female with right breast swelling and tenderness. Pathology revealed benign pathology; non-specific granulomatous mastitis. MRI examination was done at an early stage of the disease process after resistance to antibiotic treatment. A Axial T2-weighted image shows regional area of low signal intensity with corresponding intense heterogeneous non-mass enhancement (arrow) in the post-contrast dynamic series (B) and was considered suspicious (false positive). Follow-up non-contrast MRI examination by axial T2- and STIR-weighted images (C and D) shows the development of ill-defined fluid collections (arrows), consistent with a benign inflammatory process (true negative)
