An unusual case of radioactive seed migration to the vertebral venous plexus and renal artery with nerve root compromise

Seed migration to vertebral venous plexus is uncommon and to our knowledge this is the third reported case. Its subsequent migration to the renal hilum is most unusual. CT with bony windows or MRI are required if this is suspected. There is risk of spinal or nerve root damage and dose to these structures has to be estimated using GEANT4, although the tissue tolerance in the setting of low-dose rates are unknown and long-term followup of this patient is required.
