Granulomatous mastitis: gray-scale and color Doppler sonographic findings
1Department of Radiology, Istanbul University, Istanbul Faculty of Medicine, Capa, Turkey.
Purpose:
We examined the roles of gray-scale and color Doppler sonography in the diagnosis of granulomatous mastitis.
Methods:
We retrospectively studied the clinical, mammographic, and sonographic findings in 10 women 24-57 years old (mean age, 35.9+/-13.9 years) who had a histopathologic diagnosis of granulomatous mastitis. All patients underwent gray-scale sonographic examination, and 8 patients were further examined with color Doppler imaging. Seven patients had previously undergone mammography.
Results:
Mammographic findings were nonspecific in all 7 patients. Gray-scale sonographic findings were compatible with mastitis in 6 (60%) of 10 patients. Doppler examination showed increased arterial and venous vascularization within and around the lesion in 5 of 8 patients, but the spectral analysis findings were not specific for granulomatous mastitis.
Conclusions:
Neither mammography nor Doppler sonography plays a significant role in the differential diagnosis of granulomatous mastitis versus fibroadenoma or carcinoma. Gray-scale sonography shows findings specific for granulomatous mastitis in some cases, but all cases require histopathologic confirmation for final diagnosis.
