Presentation
Left flank pain.
Patient Data
CT of the abdomen and pelvis demonstrates a large para-aortic mass which in places encases the aorta. It is well circumscribed and has a few small vessels passing through it. The mass results in left-sided ureteric obstruction and hydronephrosis.
An abnormality in the left hemiscrotum can be seen on the most caudal aspect of both axial and coronal reconstructions.
US reveals a somewhat heterogenous low echogenicity mass within the left testicle which is enlarged (5.6 cm). The testicle demonstrates normal blood flow.
Case Discussion
The diagnosis or testicular seminoma was confirmed histologically following orchiectomy.
