Actinomycosis is an uncommon disease with clinical and radiographic findings that overlap those of other inflammatory and neoplastic conditions. A retrospective review of CT scans in six proved cases revealed a spectrum of findings, including soft-tissue mass with various degrees of infiltration and abscess formation. Administration of IV contrast material was helpful in defining the loculations of the abscess in two cases. Areas of involvement included the neck (two cases), liver (one case), abdominal wall (one case), thorax (one case) and kidney and retroperitoneum (one case). CT findings of a soft-tissue mass in the neck, lungs, or abdomen, with or without a draining sinus or fistula, raise the possibility of actinomycosis in patients with clinical findings that suggest a subacute or chronic inflammatory process.
放线菌病是一种罕见疾病，其临床和影像学表现与其他炎症性和肿瘤性疾病有重叠。对6例确诊病例的CT扫描进行回顾性分析发现了一系列表现，包括伴有不同程度浸润的软组织肿块和脓肿形成。在2例病例中，静脉注射对比剂有助于明确脓肿的分隔情况。受累部位包括颈部（2例）、肝脏（1例）、腹壁（1例）、胸部（1例）以及肾脏和腹膜后（1例）。颈部、肺部或腹部出现软组织肿块，无论有无引流窦道或瘘管，对于有提示亚急性或慢性炎症过程临床表现的患者，都提示有放线菌病的可能。
