Abstract
A 13-year-old HIV-positive boy with poorly differentiated nasopharyngeal carcinoma underwent both contrast-enhanced CT and 18F-FDG–PET/CT for staging and radiotherapy planning. Both examinations demonstrated a right-side nasopharyngeal mass, bilateral cervical lymph node involvement, and a metastatic lesion in the right posterior parietal pleura. After the patient had received two cycles of chemotherapy, ce-CT showed a partial response to chemotherapy but with the persistence of enlarged cervical lymph nodes and posterior right pleural thickening. 18F-FDG–PET/CT, however, showed a complete metabolic response, confirming the higher accuracy of this method in early post-therapy evaluation.
