摘要

支氣管肺隔離症，又稱作游離肺，是下呼吸道一種罕見的先天發育異常，通常是由無法正常通氣的肺泡組織組成。在臨床上要診斷游離肺最重要的步驟是與惡性腫瘤做區隔。一般而言，正子造影是目前最頻繁使用於惡性腫瘤診斷的工具。然而，當游離肺合併有慢性發炎感染如麴菌感染時，在正子造影下也會呈現類似惡性腫瘤的成像。因此，選用肺血管攝影觀察血管供應情形，是較好的術前診斷工具。

Bronchopulmonary sequestration, also referred to as pulmonary sequestration, is a rare congenital malformation of the lower respiratory tract, in which a mass of non-functioning lung tissue is unable to communicate normally with the tracheobronchial tree. From a clinical standpoint, accurately diagnosing bronchopulmonary sequestration is crucial to the differential diagnosis of malignancies. PET-CT allows accurate differentiation between benign and malignant nodules. However, when bronchopulmonary sequestration is complicated by chronic infection from an organism such as Aspergillus, PET-CT will often detect a high FDG uptake, a symptom which may also indicate malignancy. Thus, choosing CT angiography rather than PET-CT can be critical to the accurate diagnosis of sequestration prior to pulmonary surgery.
