We report 4 cases of pathologically proven abdominal actinomycosis. US and CT demonstrated an infiltrative abdominal mass with ill-defined margins and heterogeneous enhancement after IV contrast. The ileo-cecal region was involved in one case; the mass appeared following cholecystectomy and recurred 3 years after surgical resection in one case; and no predisposing factor was identified in the 2 other cases. In one of these, recurrence was observed 12 years after the first episode. Actinomycosis must be included in the differential diagnosis of invasive abdominal lesions with "malignant" appearance.
我们报告4例经病理证实的腹部放线菌病。超声和CT显示为边界不清、静脉注射造影剂后强化不均匀的浸润性腹部肿块。1例累及回盲部；1例肿块出现在胆囊切除术后，手术切除3年后复发；另外2例未发现诱发因素。其中1例在首次发病12年后复发。放线菌病必须纳入具有“恶性”外观的侵袭性腹部病变的鉴别诊断中。
