Ultrasound features of hepatic inflammatory myofibroblastic tumor:a report of 4 cases

Objective To investigate the ultrasound features of hepatic inflammatory myofibroblastic tumor ( HIMT) . Methods A retrospective analysis was performed for the ultrasound features of 4 patients who visit Shengjing Hospital from February 2007 to July 2017 with pathologically confirmed HIMT, including the location, size, boundary, morphology, internal echo, and blood flow of lesions. Results The patients were aged 2-69 years and there were 2 male and 2 female patients. All 4 patients had single tumor with a maximum diameter of 3. 4-21. 2 cm. Two patients had clear boundaries and two had unclear boundaries. Two patients had solid tumor with inhomogeneous low echo and 2 had mixed cystic and solid type; color Doppler flow imaging found blood flow signal in tumor in all patients. Conclusion Ultrasound can clearly reveal the size, internal echo, and blood flow of HIMT, but the ultrasound images of HIMT lack specificity. Pathological examination is still needed for a confirmed diagnosis.
