This is 47 year old male patient complaining of lower back pain without radiculopathy.
Observe the calcification within the vas deferens which diverges from the midline above the pubis in a tubular pattern. On occasion the vas deferens can be traced along its course through the inguinal canal to the scrotum. This calcification is benign in nature and actually pathognomonic for diabetes. It is somewhat unusual for a patient of this young age to have vas deferens calcification. No further imaging of this is necessary and this is not thought to be symptom generating.
