    Idiopathic Granulomatous Mastitis: Magnetic Resonance Imaging Findings with Diffusion
    (2016) Aslan, Hulya; Pourbagher, Aysin; Colakoglu, Tamer; https://orcid.org/0000-0002-7138-246X; 26508792; AAK-9104-2021
    Background: Idiopathic granulomatous mastitis (IGM) is a rare benign breast disease with unknown etiology which can mimic breast carcinoma, both clinically and radiologically. Magnetic resonance imaging (MRI) findings of IGM have been previously described; however there is no study evaluating diffusion-weighted MRI findings of IGM. Purpose: To analyze conventional, dynamic contrast-enhanced, and diffusion-weighted MRI signal characteristics of IGM by comparing it with the contralateral normal breast parenchyma. Material and Methods: A total of 39 patients were included in the study. On dynamic contrast-enhanced MRI, the distribution and enhancement patterns of the lesions were evaluated. We also detected the frequencies of involving quadrants, retroareolar involvement, accompanying abscess, and skin edema. T2-weighted (T2W) and STIR signal intensities and both mean and minimum apparent diffusion coefficient (ADC) values were compared with the contralateral normal parenchyma. Results: IGM showed significantly lower mean and minimum ADC values when compared with the normal parenchyma. Signal intensities on T2W and STIR sequences of the lesion were significantly higher than the normal parenchyma. On dynamic contrast-enhanced MRI, 7.7% of the patients had mass-like contrast enhancement, 92.3% of the patients had non-mass-like contrast enhancement. Abscess was positive in 33.3% of the patients. Conclusion: As a result, IGM showed commonly non-mass-like lesions with restricted diffusion. Although it is a benign pathology, it may show clustered ring-like enhancement like malignant lesions.

    Is There A Correlation Between the Severity of Idiopathic Granulomatous Mastitis and Pre-Treatment Shear-Wave Elastography Findings? Original Research
    (2018) Aslan, Hulya; Arer, Ilker Murat; Pourbagher, Aysin; Ozen, Merve; 0000-0002-7138-246X; 30665211; AAK-9104-2021; HCH-8774-2022
    AIM: The aim of this study was to analyze the correlation between the severity of idiopathic Garulomatous Mastitis (IGM) and the pre-treatment Shear-Wave Elastography (SWE) findings. MATERIAL AND METHODS: A total of 39 patients diagnosed with granulomatous mastitis were included in the study between the dates of December 2014 and February 2017. The patients were divided into two groups. Group 1 was treated using a conservative protocol and steroids. Group 2 was treated surgically. Pre-treatment SWE findings of both groups were compared. RESULTS: The mean ages of the patients in group 1 and 2 were 38.44 +/- 9.6 and 3605 +/- 7.44 years, respectively. There were not any significant differences between the groups with regard to frequency of BI-BADS categories and Virtual touch tissue imaging (VTI) patterns. The mean Shear-Wave Spead (SWS) were 1.98 +/- 1.02 m/sec and 2.82 +/- 1.66 m/sec in group 1 and 2 respectively. The difference was not significant (p >= 0.05). The BI-RADS categories and VTI patterns did not show significant difference when the recurrent and non-recurrent patients were compared. CONCLUSION: There may not be a correlation with the pre-treatment SWE findings and severity of the IGM.
