Retroperitoneal teratoma comprises 3.5−4% of all germ cell tumors in children and 1−11% of primary retroperitoneal neoplasms. The imaging findings are distinctive. The present report is a case of a 4-month-old girl in whom a retroperitoneal teratoma was found to have classical appearance on imaging. The tumor was resected and histopathological examination confirmed the diagnosis of immature, high grade, teratoma.
