Descending necrotizing mediastinitis (DNM) is a rare and life-threatening complication of deep neck space infection which occurs when infection spreads from the deep spaces of the neck, propagating within the soft tissue into the mediastinal spaces. The disease has a high mortality rate due to frequent delay in diagnosis and treatment. Computed Tomography (CT) is important in determining the level of infection, showing the presence and extension of fluid collections (with or without gas bubbles) and diffuse soft-tissue infiltration of the mediastinal fat, and indicating the best surgical approach and progress of treatment. Three cases of DNM evaluated with spiral CT from June 1999 to June 2001 are presented.
下行性坏死性纵隔炎（DNM）是深部颈部间隙感染的一种罕见且危及生命的并发症，当感染从颈部深部间隙蔓延，在软组织内扩散至纵隔间隙时就会发生。由于诊断和治疗常常延误，该病死亡率很高。计算机断层扫描（CT）对于确定感染程度很重要，它能显示液体积聚（有无气泡）的存在及范围，以及纵隔脂肪的弥漫性软组织浸润情况，并指明最佳手术方式和治疗进展。本文介绍了1999年6月至2001年6月间经螺旋CT评估的3例DNM病例。
