Contrast-enhanced ultrasound features of breast capillary hemangioma: a case report and review of literature

Breast capillary hemangioma is a rare benign vascular tumor. A 59-year-old asymptomatic woman underwent screening mammography and breast ultrasound. B-mode ultrasound revealed a lobulated, hypoechoic mass. Color Doppler ultrasound showed no intratumoral blood flow. Contrast-enhanced ultrasound (CEUS) revealed internal fast homogeneous contrast enhancement of the mass and persistent enhancement after 4 min. A 14-gauge core needle biopsy was then performed. The radiologic and pathologic appearances were concordant with breast capillary hemangioma. The ultrasonic manifestations of breast hemangioma may vary, and differentiation from other inflammatory diseases and malignancies is challenging. CEUS may help in observing the vascular characteristics of breast capillary hemangioma.
