Objective:To assess the diagnostic value of dynamic T1 weighted (T1w) gadolinium ethoxybenzyl diethylenetriamine penta-acetic acid (Gd-EOB-DTPA)-enhanced MR cholangiography (MRC) for the detection of active bile leaks.Methods:A total of 28 patients with suspected biliary leakage who underwent routine T2 weighted (T2w) MRC and T1w GD-EOB-DTPA-enhanced MRC at our institution from February 2013 to June 2016 were included in this study. The image sets were retrospectively analyzed in consensus by three radiologists. T1w Gd-EOB-DTPA-enhanced MRC findings were correlated with clinical data, follow-up examinations and findings of invasive/surgical procedures. Patients with positive bile leak findings in Gd-EOB-DTPA-enhanced MRC were divided into hepatobiliary phase (HBP) (20–30 min) and delayed phase (DP) (60–390 min) group according to elapsed time between Gd-EOB-DTPA injection and initial bile leak findings in MRC images. These groups were compared in terms of laboratory test results (total bilirubin, liver en...

A 23-year-old woman with a 2-year history of discoid lupus (SLE) presented with a right lateral upper quadrant breast mass. Physical examination revealed a 5 cm irregular, hard lesion suggestive of a breast malignancy. Ultrasound-guided fine needle aspiration biopsy of the mass confirmed the diagnosis as lupus mastitis. Differential diagnosis of a breast mass in a patient with SLE must include the possibility of lupus mastitis. Surgical resection is usually not necessary, and medical treatment can be implemented successfully.
