Subdural empyema post-chemoradiotherapy for nasopharyngeal carcinoma.

Nasopharyngeal carcinoma is a common malignancy in the Asian Chinese population. The first-line treatment for Stage III/IV disease has in recent times shifted from radiotherapy to that of concurrent chemoradiotherapy. The treatment is not infrequently associated with in-field complications. We describe a rare case of one such complication -- subdural empyema developing post-chemoradiotherapy in a 56-year-old man with Stage IVB nasopharyngeal carcinoma.
