In the last decade, several sophisticated and accurate imaging methods such as positron emission tomography have been developed in order to evaluate malignant potential in enlarged mediastinal lymph nodes. This case illustrates an unusual presentation of sarcoidosis that mimicked lymphatic metastases of non small cell lung carcinoma. The reported high specificity and sensitivity of positron emission tomography-Computer Tomography regarding mediastinal staging could lead in same cases of false positives to a delaying of stage adapted therapy of non small cell lung carcinoma, showing that despite the recent advances of imaging techniques, such as positron emission tomography-computer tomography, several limitations of this imaging technique are still existing.
在过去十年中，已经开发了几种复杂且准确的成像方法，如正电子发射断层扫描，以评估肿大纵隔淋巴结的恶性潜能。本病例展示了结节病的一种不寻常表现，其酷似非小细胞肺癌的淋巴转移。报道的正电子发射断层扫描-计算机断层扫描在纵隔分期方面的高特异性和敏感性，在某些情况下可能导致假阳性，从而延迟非小细胞肺癌的分期适应性治疗，这表明尽管成像技术如正电子发射断层扫描-计算机断层扫描有了最新进展，但这种成像技术仍存在一些局限性。
