Acute and subacute infection in the mediastinum, though rare, is associated with a substantial mortality which increases with delay in diagnosis. The conventional radiographic and computed tomographic studies of 14 patients with proven infective mediastinitis were reviewed in an attempt to identify their relative roles in its diagnosis. Signs of infection demonstrated by computed tomography (CT) included abscess formation, mediastinal masses, soft tissue collections contiguous with other infected compartments and areas of diffuse mediastinal infiltration with fat plane loss without prominent lymphadenopathy. The anatomy and extent of the infection was well delineated by CT in all patients. In nine cases this information affected clinical management, facilitating percutaneous drainage of the abscess in three. In five patients, information from CT did not alter clinical management.
纵隔急性和亚急性感染虽罕见，但死亡率很高，且随着诊断延迟而增加。回顾了14例经证实为感染性纵隔炎患者的传统X线和计算机断层扫描研究，以确定它们在诊断中的相对作用。计算机断层扫描（CT）显示的感染迹象包括脓肿形成、纵隔肿块、与其他感染腔相邻的软组织聚集以及弥漫性纵隔浸润区域伴脂肪平面消失且无明显淋巴结肿大。CT清晰显示了所有患者感染的解剖结构和范围。在9例患者中，这些信息影响了临床管理，其中3例患者因此便于进行脓肿的经皮引流。在5例患者中，CT提供的信息未改变临床管理。
