Abstract:
Purpose To analyze the ultrasonic manifestations of extrarenal extracranial malignant rhabdoid tumor(EERT)in children to enhance the awareness of its early diagnosis.Materials and Methods Clinical data of 13 children with EERT diagnosed by pathology from the Children's Hospital of Chongqing Medical University were collected retrospectively from January 2014 to March 2024.The ultrasonic manifestations of these cases were summarized and compared with their pathological results.Results Among the 13 children with EERT,10 cases had tumors located in soft tissues of the extremities,and 3 cases had tumors located in the abdomen.The tumors showed irregular shapes and indistinct borders on ultrasonic images,and the average of the maximum diameters of the tumors measured by ultrasound was(10.43±2.57)cm.The interior of the tumors mostly appeared as heterogeneous hypoechoic lesions;9 of the tumors were accompanied by small patchy regions of anechoic areas(cystic degeneration or liquefaction);9 of the tumors were accompanied by strong echoes(calcification);12 of the tumors had relatively abundant blood supply.Conclusion Ultrasonic images of EERT in children have certain characteristics.Mastering the ultrasonic manifestations could assist in the clinical diagnosis and follow-up of this disease.
