BACKGROUND Primary hepatic angiosarcoma(PHA)is a rare malignant tumor of the vascular endothelium.Clinical manifestations and laboratory and imaging examinations often lack specificity for PHA.We report a case of PHA,and describe the ultrasound characteristics and characteristic changes in laboratory values associated with PHA.CASE SUMMARY A 75-year-old woman presented with right upper quadrant abdominal pain for half a month.Magnetic resonance imaging(MRI)at a local hospital revealed multiple liver space-occupying lesions,and she was admitted to our hospital for further diagnosis.Contrast-enhanced ultrasound(CEUS)revealed multiple slightly hyperechoic nodules in the liver,which were suspected to be of malignant vascular origin.Contrast-enhanced computed tomography revealed multiple lowdensity nodules in the liver,considered to be metastatic hematopoietic malignancies.Contrast-enhanced MRI showed that the multiple liver nodules shared features with infectious lesions.Laboratory examination revealed normal alpha-fetoprotein levels,slightly increased other liver enzymes,decreased platelets,and significantly increased D-dimer levels.Liver biopsy and histopathology confirmed the presence of PHA.CONCLUSION CEUS can provide valuable clues for the diagnosis of PHA and greatly improve the success rate of puncture biopsy.
