Abstract: 　Objective　To explore the imaging features of pediatric splenic primary solitary tumor. Methods　The medical imaging appearances of 6 children with splenic primary solitary tumor confirmed by surgery and pathology from January 2010 to August 2015 were retrospectively studied. The related literatur were reviewed. Results　In 6 children, 2 children of cystic lesions, ultrasound showed anechoic mass, CT scan showed low density mass, without change after contrast, pathologically confirmed as congenital cyst; 2 children’s ultrasound showed solid echo, color Doppler ultrasound explored the blood flow signals, contrast CT showed the lower strength around the splenic parenchyma, pathologically confirmed as splenic lymphangioma; one child’s unltrasound showed echo mass with rich signals of blood flow, MRI scans showed T1WI, T2WI and other signals of lumps, with little homogenity after contrast, pathologically confirmed as splenic hamartoma; one child’s ultrasound cannot distinguish tumor boundaries, contrast CT scan showed concentric filling reinforcement, pathologically confirmed as hemangioma. Conclusion Splenic primary solitary tumor in children is rare. There are no specific clinical characteristics. The image findings can define the locations and help the differential diagnosis. The final diagnosis depends on pathology.
