Abstract

Our aim is to present the case report of a woman affected by tracheal granular cell tumor analysed by multiphasic contrast-enhanced multidetector CT. The tumor presents as polypoid lesion (diameter 13 mm), with smooth and well-defined margins, elevated contrast enhancement in arterial phase, and a modest release of contrast in venous phase. This pattern is quite different from the other tracheal tumours. We have performed a comprehensive review of literature to assess all cases of granular cell tumors of the trachea; only 40 cases are reported. Of these, no one focused on the contrast enhancement aspect, so our work is the first showing a specific pattern in multidetector computed tomography (MDCT) of the tracheal granular cell tumour and may help in differential diagnosis.

摘要

我们的目的是呈现一例经多期对比增强多层螺旋CT分析的气管颗粒细胞瘤女性患者的病例报告。肿瘤表现为息肉样病变（直径13毫米），边缘光滑且清晰，动脉期对比增强升高，静脉期对比剂有适度廓清。这种表现模式与其他气管肿瘤有很大不同。我们对文献进行了全面回顾，以评估所有气管颗粒细胞瘤病例；仅报告了40例。其中，没有人关注对比增强方面，因此我们的工作首次展示了气管颗粒细胞瘤在多层螺旋计算机断层扫描（MDCT）中的特定表现模式，可能有助于鉴别诊断。
