A distinguishing feature has been noted to help differentiate between malignant retroperitoneal nodes and nodes which contain reactive hyperplasia. This sign is the presence of a cleavage plane between the mass of nodes and the great vessels which are easily visible in benign disease. This distinction is in reference to malignant nodal disease where the contours of the vessels are obscured. The ability to make a diagnosis of benign disease on CAT scan has enabled us to choose the appropriate course of therapy and, in some patients, allowed us to avoid exploratory laparotomy for diagnosis.
已注意到一个显著特征有助于区分恶性腹膜后淋巴结和伴有反应性增生的淋巴结。该征象是在淋巴结团块与大血管之间存在一个劈裂平面，这在良性疾病中很容易看到。这种区别是针对恶性淋巴结疾病而言，在恶性疾病中血管轮廓模糊不清。通过CT扫描诊断良性疾病的能力使我们能够选择合适的治疗方案，并且在一些患者中，使我们能够避免为诊断而进行的剖腹探查术。
