Abstract

Background: Metanephric adenoma is an extremely rare renal neoplasm, especially in pediatrics. Chemotherapy combined with surgery in metanephric adenoma has not been reported.

Methods: We describe a case of metanephric adenoma in a child less than 2 years old, which were treated by chemotherapy combined with surgery.

Results: Nephron sparing surgery was performed after regular chemotherapy, and the pathological result was metanephric adenoma.

Conclusion: Pediatric metanephric adenoma is extremely rare; the clinical manifestations and imaging examinations lack specificity. Nephron sparing surgery is recommended as the preferred treatment for metanephric adenoma. Long-term follow-up and more in-depth molecular genetic research are still needed to determine the benign or malignant of metanephric adenoma and whether chemotherapy drugs have an effect on it.

Keywords: chemotherapeutics; children; metanephric adenoma; nephron sparing surgery; operation treatment.

(A) CT plain scan before chemotherapy: CT value was 46 HU. (B) CT enhanced before chemotherapy: the third stage showed obvious uneven enhancement, with CT values of about 58 HU, 98 HU, and 133 HU, respectively.

(A) MRI plain scan before chemotherapy: equisignal on T1WI, slightly higher signal on T2WI, significantly higher signal on DWI, and low signal on ADC. (B) MRI enhancement before chemotherapy: dynamic enhancement showed delayed uneven enhancement, and the degree was weaker than that of renal cortex.
