Radiologist, Nuclear Medicine 's  Response
FDG (the medicine used in PET scan) uptake in castleman disease is modest. No large scale studies have established the role of PET-CT in castleman disease.

PET scan combined with a contrast CT can be done in this condition, though it is not obvious if addition of PET scan will add significantly to the treatment of the patient.
