We report the first case of an isolated choanal fungus ball in a 28-year-old man with a previous history of nasopharyngeal carcinoma, who was treated with radiotherapy 14 years ago. The initial diagnosis was a recurrent tumour or a secondary neoplasm. Histopathological examination confirmed a fungal infection. There are no previous reports of a fungus ball located at the posterior choanal region. Although it has been reported that bacteriology of sinonasal region would be different in irradiated patients, there is no study reporting fungal infections in irradiated patients in English literature. In this report, the clinical presentation, relevant radiologic findings and management of sinonasal fungus ball and its relationship with previous radiotherapy were discussed with the literature knowledge.
我们报告了首例孤立性后鼻孔真菌球的病例，该患者为 28 岁男性，既往有鼻咽癌病史，14 年前接受过放射治疗。最初的诊断是复发性肿瘤或继发性肿瘤。组织病理学检查证实为真菌感染。此前没有报告位于后鼻孔区域的真菌球的病例。虽然有报道称，接受放射治疗的患者的鼻窦区域的细菌学情况会有所不同，但在英文文献中，没有关于放射治疗患者真菌感染的研究报告。在本报告中，我们结合文献知识讨论了鼻窦真菌球的临床表现、相关影像学发现和治疗及其与既往放射治疗的关系。
