We report the case history of a patient who was treated with radiotherapy for nasopharyngeal carcinoma. During follow-up, she showed signs, symptoms and radiological evidence of disease recurrence and progression. However, repeated biopsies of the posterior nasal space (PNS) failed to demonstrate malignancy. A diagnosis of nasopharyngeal tuberculosis was finally made when tissue from a PNS biopsy stained positive for acid-fast bacillus. The patient responded to antituberculous chemotherapy.
我们报告了一名接受鼻咽癌放射治疗患者的病史。在随访期间，她出现了疾病复发和进展的体征、症状及影像学证据。然而，对后鼻间隙（PNS）进行的多次活检均未显示恶性肿瘤。当PNS活检组织的抗酸杆菌染色呈阳性时，最终确诊为鼻咽结核。该患者对抗结核化疗有反应。
