MRI Evaluation of Pediatric Malignant Abdominal Tumors

Abstract

Mostly, pediatric abdominal tumors are benign. Eventually, malignant cancer may occur as abdominal tumor being the Wilms tumor, neuroblastoma, hepatoblastoma, and Burkitt's lymphoma found to be common on this age group. Abdominal tumors can have a wide etiology range that can be classified according to its location, age group, and associated signs and symptoms. Mostly, benign findings are hydronephrosis, infectious hepatosplenomegaly, and ascariasis, while neuroblastoma, Wilms tumor, and germ cell tumors can exhibit specific MRI findings helping on its determination. This article discuss some clinical and MRI presentation of main abdominal pediatric malignances, as well as imaging findings that can correlate to clinical aspects to help during staging and patients' treatment follow up.
