Abstract：Objective: To investigate the differential diagnosis of MR imaging findings of male breast cancer and inflammatory granuloma. Methods: Confirmed by operation and pathology, 4 cases of male breast cancer and 6 cases of granulomatous mastitis were underwent dynamic contrast-enhanced MR imaging and DWI. Results: The location of the lesions in the two groups were all behind the nipple, and all showed mass lesion. 2 cases of breast cancer were morphologically oval, irregular in 2 cases; clear edge in 2 cases and irregular shape in 2 cases. Internal inhomogeneous enhancement in 2 cases and edge enhancement in 4 cases. 2 cases of skin were involved. The TIC curve showed 3 cases of type Ⅲ, 1 cases of type Ⅱ. The average ADC value was of 0.897×10-3 mm2/s. Inflammatory granuloma were morphologically oval in 2 cases and irregular in 4 cases. There was irregular edge and spiculated in 2 cases. Internal inhomogeneous enhancement in 2 cases and edge enhancement in 4 cases. The TIC curve were all of type Ⅱ. The average ADC value of 0.901×10-3 mm2/s. The edge of the mass were enhanced highly, edge enhancement is higher than that of the center(3 cases) or uneven enhancement(1 cases). There was no enhancement zone (4 cases) in the inflammatory granuloma group. There was no obvious enhancement in the area where high intensity on T2WI. Centrifugal enhanced and the edge of the lesion gradually blurred in the dynamic images(2 cases). Conclusion: For the diagnosis of male breast cancer and inflammatory granuloma lesions, internal enhancement and enhancement curves play an important role in the differential diagnosis of disease in two groups. Breast cancer lesions were of inhomogeneous enhancement or obvious enhancement. Edge enhancement is higher than that of center curve and with TIC curve type Ⅲ. No enhancement area could be observed in granuloma group lesions. Centrifugal enhancement and the edge of lesions gradually blurred could be observed on dynamic image. Enhancement curve were type Ⅱ.
