We herein present a rare case of breast fibromatosis, the contrast-enhanced ultrasonography (CEUS) findings of which we believe have never been described. The high similarity between the clinical and imaging manifestations of breast cancer makes its differential diagnosis difficult. In this report, we describe the CEUS findings of a less common type of fibromatosis, discuss the potential value of CEUS to differentiate it from malignant breast lesions, and briefly review the literature.

Abstract Background: To investigate arrival-time parametric imaging (At-PI) in contrast-enhanced ultrasonography (CEUS) for diagnosing fibrosis in primary biliary cholangitis (PBC). Methods: Participants were 48 patients (male/female: 8/40; mean age, 60 ± 13 years) with PBC diagnosed by liver biopsy who underwent CEUS during 2009-2019. Of these, 27 (male/female: 4/23; mean age, 61 ± 13 years) who also underwent shear wave elastography (SWE) were further analyzed. SonazoidTM was intravenously injected and CEUS performed. Contrast dynamics of hepatic segment V and the right kidney were recorded. At-PI were generated from the recorded video clips. Contrast arrival time <5 s was displayed in red, and the ratio of red (ROR) area to the entire liver contrast-enhanced area was calculated. ROR and shear wave velocity (Vs) measured by SWE were compared by fibrosis stage (F0-F3), bile duct loss score, cholangitis activity, hepatitis activity (HA0-HA3), and disease stage (stage 1-4), as determined by liver biopsy.Results: ROR significantly differed between F0 and F2-F3 and between F1 and F2-3. Using ROR to diagnose ³F1 (³F2), area under the receiver operating characteristic curve (AUROC) was 0.77 (0.92) (cutoff, 36.7% [47.1%]; sensitivity, 0.75 [0.92]; specificity, 0.82 [0.81]). Vs significantly differed between F0 and F1, F0 and F2-3, and HA0 and HA1. For diagnosing ³F1 (³F2), Vs had AUROC of 0.84 (0.80) (cutoff, 1.23 m/s [1.40 m/s]; sensitivity, 0.75 [0.60]; specificity, 0.82 [0.86]).Conclusions: At-PI was useful for diagnosing fibrosis, especially F2 or worse, in PBC, suggesting that At-PI can correctly diagnose fibrosis regardless of hepatic inflammation.

Purpose: A meta-analysis was conducted to evaluate the diagnostic performance of contrast-enhanced ultrasonography using the contrast agent SonoVue to differentiate benign from malignant breast lesions. Method: A comprehensive search of the literature was performed using the Embase, PubMed, and Web of Science databases to retrieve studies published before February 2020. Data were extracted, and pooled sensitivity, specificity, and diagnostic odds ratios were calculated with meta-analysis software. Heterogeneity was evaluated via the Q test and I2 statistic. Meta-regression and subgroup analyses were applied to evaluate potential sources of heterogeneity. Publication bias was assessed using the Deeks’ funnel plot asymmetry test. A summary receiver operating characteristic curve (SROC) was constructed. Results: A total of 27 studies including 5378 breast lesions subjected to CEUS examination with SonoVue were included in the meta-analysis. The pooled sensitivity and specificity values were 0.90 (95% confidence interval [CI], 0.88–0.91; inconsistency index [ I2] = 75.7%) and 0.83 (95% CI, 0.82–0.85; I2 = 91.0%), respectively. The pooled diagnostic odds ratio was 48.35% (95% CI, 31.22–74.89; I2 = 77.6%). The area under the summary receiver operating characteristic curve (AUC) was 0.9354. Meta-regression analysis revealed the region of patient residence and dose of contrast agent as potential sources of heterogeneity (P < .01). Subgroup analysis showed a higher area under the summary receiver operating characteristic curve for European and higher contrast agent dose subgroups (P < .05). Conclusion: Contrast-enhanced ultrasonography with SonoVue displays high sensitivity, specificity, and accuracy when differentiating benign from malignant breast lesions. Despite its current limitations, this technique presents a promising tool for diagnosing breast lesions in clinical practice.
