Abdominal sonography in six febrile patients was suspicious for parenchymal gas. In five, immediate radiographic confirmation was obtained. Four patients had gas-containing abscesses, one had gas sequestered in a hepatic hematoma, and in the other subcapsular hepatic gas probably originated by mesenteric dissection from pneumatosis cystoides intestinals.
对6名发热患者进行腹部超声检查，结果怀疑存在实质脏器积气。其中5名患者随即通过影像学检查得以确诊。4名患者患有含气脓肿，1名患者肝血肿内有积气，另1名患者肝包膜下积气可能源于肠壁囊样积气症的肠系膜剥离。
