“…Two sonograms were found to be normal. These findings are similar to those previously described [5,[10][11][12][13]21]. The blood signal of non-puerperal mastitis on CDFI was further studied in our series.…”

“…Mammographic findings are considered non-specific, and these data are in agreement with our findings. Although Lequin et al [10] first revealed non-circumscript lesions (24/41), other authors have described other findings such as multiple small masses, an irregular illdefined mass or a focal asymmetric density to be more common [5,[11][12][13]21]. Our study showed that the most common mammographic appearance was a focal/ diffuse asymmetric density (12/25).…”

“…The most frequently used classification subtypes are subareolar abscess of the breast, mastitis complicating fibrocystic disease, inflammation of a cyst and plasma cell mastitis [10,20]. Non-puerperal mastitis usually affects females under 40 years old [5,10,11,13], which was reflected in our study (the mean age of our patients was 37.5 years). Females with non-puerperal mastitis typically present with a breast mass that may be associated with pain, skin thickening or axillary adenopathy.…”

“…These aforementioned manifestations in non-puerperal mastitis are slight or rare [8]. Inflammatory breast cancer usually affects females of approximately 50 years old [26,27], but non-puerperal mastitis is more common in females under 40 [5,10,11,13]. MRI is highly sensitive for depicting primary breast parenchymal lesions and global skin abnormalities that may help diagnose inflammatory breast cancer.…”

“…However, the appearance of nonpuerperal mastitis on mammography and sonography is non-specific [5,[10][11][12][13]. MR mammography is useful for the detection of non-puerperal mastitis, but the published literature on using MRI to detect nonpuerperal mastitis is sparse [7,13,14].…”

Objective: To describe the radiological and clinical features of adult non-puerperal mastitis and to determine the most accurate method of preventing unnecessary surgical procedures.Methods: Clinical and imaging findings were retrospectively reviewed in 51 females with non-puerperal mastitis, which was confirmed by biopsy/surgical pathology. All 51 patients had pre-operative MRI; 45 patients also had sonograms and 25 also had mammograms, pre-operatively.Results: Of the 51 cases with non-puerperal mastitis, 94.1% (48/51) were confirmed as having acute or chronic inflammation, and the other 3 had plasma cell mastitis; areola papillaris inflammation was found in 39.2% (20/51) of the cases. Overall, 6 of the 25 cases that were examined with mammography and 2 of the 45 cases that were examined with sonography appeared normal, but all 51 lesions were positively identified on MRI. Asymmetrical density (12/25) on mammograms and solitary or separated/ contiguous, clustered, hypoechoic mass-like lesions (31/45) on ultrasound were the most common signs of non-puerperal mastitis. On enhanced MRI, 90.2% (46/51) of patients showed non-mass-like enhanced lesions. Multiple regional enhancements in the pattern of distribution (32/46) and separated or contiguous, clustered, rim-like enhancements in the pattern of internal enhancement (29/46) were the most common manifestations in nonmass-like enhanced lesions. Of the 51 patients, mastitis Type 1 and Type 2 in the time-signal intensity curve were detected in 47.1% and 51.0% of the patients, respectively. The breast imaging reporting and data system categories with the highest number of patients were Category 0 (9/ 25) on mammography, Category 4a on sonography (18/45) and Category 4a on MRI (29/51). Conclusion:The findings from mammography and ultrasound are non-specific; therefore, using MR can be helpful in the diagnosis, especially in the presence of non-mass-like enhancements that are multiple, regional, separated, or contiguous, clustered and rim-like.
