title: F-18 FDG PET/CT imaging of metastatic extrarenal Wilms tumor arising in the inguinal canal.
abstract: Extrarenal Wilms tumor (ERWT) is rare, and has been reported sporadically in the literatures. ERWT can arise anywhere from the renal bed to the testes; reported locations of ERWTs include the retroperitoneum, inguinal canal, endocervix, uterus, epididymis, and sigmoid mesocolon. We report the F-18 FDG PET/CT imaging findings of an ERWT arising from the inguinal canal in a 9-year-old boy. F-18 FDG accumulated in the metastatic lesions of the lung and mediastinal lymph nodes, as well as the primary ERWT. After chemotherapy, a follow-up PET/CT showed complete metabolic remission. F-18 FDG PET/CT is useful in detecting primary and metastatic ERWTs and in evaluating treatment response.
