Seminomas complicating undescended intraabdominal testes in patients with prior negative findings from surgical exploration

OBJECTIVE. This paper describes the clinical and imaging characteristics of seminoma complicating intraabdominal testes in three patients who had a hi story of negative findings from surgical exploration of the inguinal canal and scrotum. CONCLUSION. Because inguinal surgery for cryptorchidism may fail to disclos e intraabdominal testes, surgery that has negative findings should be follo wed up by a close examination of the abdomen. Seminomas arising from an int raabdominal testis can be large and asymptomatic or may simulate other dise ases. Torsion may occur and occasionally appear as acute abdomen. The imagi ng features can be nonspecific, and the history of cryptorchidism may not b e provided. Awareness of the clinical and imaging features of neoplasms inv olving undescended intraabdominal testes is important for appropriate diagn osis and therapy.
