Presentation
Distant history of nasopharyngeal carcinoma irradiation.
Patient Data
Age: Adult
From the case:
Cystic radionecrosis
Axial non-contrast
Non-contrast CT demonstrates bilateral hypodensity of the temporal poles with cysts and small areas of intracystic hemorrhage. On the left a large cyst exerts significant mass effect. In the setting of prior nasopharyngeal carcinoma treated with radiotherapy, the likely diagnosis is radionecrosis. A radiation-induced tumor could co-exist.
Case Discussion
Patient underwent a craniotomy and cyst decompression.
Histology confirmed radiation necrosis with no evidence of infection or tumor.
