Pulmonary sequestration has always been diagnosed by direct demonstration of the vessels tributary to the lesion, usually by angiography. Conventional CT can identify the arterial supply in only two thirds of cases. We report a case of pulmonary sequestration diagnosed using Spiral CT, based on the demonstration of both arterial supply and venous drainage. The capabilities of Spiral CT to detect subtle vessel abnormalities and to yield reliable multiplanar imaging enabled us to show the whole course of both the artery and the vein tributary to the lesion. Axial images were the most useful ones to diagnose pulmonary sequestration; 2D and 3D reconstructions were useful for a detailed and immediate spatial depiction of the parenchymal abnormality and of its vascular pedicle.
肺隔离症一直通过直接显示病变的供血血管来诊断，通常采用血管造影术。传统CT仅能在三分之二的病例中识别出供血动脉。我们报告一例使用螺旋CT诊断的肺隔离症病例，该诊断基于对供血动脉和引流静脉的显示。螺旋CT检测细微血管异常以及提供可靠多平面成像的能力，使我们能够展示病变供血动脉和静脉的全程。轴位图像对诊断肺隔离症最为有用；二维和三维重建对于详细且直观地显示实质异常及其血管蒂的空间结构很有帮助。
