Paragangliomas are rare neuroendocrine tumours sharing embryological origins with phaeochromocytomas but differ in that they are found outside the adrenal medulla. The prevalence in literature ranges from 2 to 8 cases per million people. Pulmonary paragangliomas account for approximately 2% of this. Paragangliomas can cause symptoms due to the secretion of catecholamines. Other 'non-functional' paragangliomas may cause symptoms relating to mass effect or endobronchial obstruction. Once a diagnosis is made, the most common reported modality of management are lobectomy and endobronchial sleeve resection. Only a limited number of case reports describe other management modalities such as endobronchial ablation. We present the case of 48-year-old female with a right main bronchus endobronchial lesion identified on positron emission tomography (PET) dotatate scan on a background of succinic dehydrogenase B gene mutation (SDHB) familial paraganglioma. Bronchoscopic management with argon plasma coagulation (APC) probe ablation was used to debulk the lesion which resulted in excellent symptomatic improvement and stability on follow-up.
副神经节瘤是一种罕见的神经内分泌肿瘤，与嗜铬细胞瘤有着共同的胚胎学起源，但不同的是，它们位于肾上腺髓质之外。文献报道的发病率为每百万人中有2至8例。肺副神经节瘤约占其中的2%。副神经节瘤可因儿茶酚胺分泌而引起症状。其他“无功能”副神经节瘤可能会引起与占位效应或支气管内阻塞相关的症状。一旦确诊，最常见的治疗方式是肺叶切除术和支气管袖状切除术。只有少数病例报告描述了其他治疗方式，如支气管内消融。我们报告一例48岁女性患者，在琥珀酸脱氢酶B基因突变（SDHB）家族性副神经节瘤背景下，正电子发射断层扫描（PET）钇[90Y] DOTATATE扫描发现右主支气管内病变。采用氩等离子体凝固（APC）探头消融进行支气管镜治疗，以减少病变体积，症状得到显著改善，随访期间病情稳定。
