[Post-radiation pneumonitis in a case of Hodgkin's lymphoma assessed with PET-FDG by residual mediastinal mass].
The PET-FDG is a useful method to assess the post-radiotherapy residual masses in supradiaphragmatic lymphoma patients. We present the case of a patient with residual mediastinic mass revealed by CT after the patient had completed treatment for Hodgkin's disease and in whom the PET study demonstrated a typical pattern of post-radiation pneumonitis. When these patients are re-assessed early after radiotherapy, the different tracer uptake patterns should be taken into account in order to identify the existence of radiotherapy sequela and avoid false positive results.
