Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by multiple gas-filled cysts of varying size within the intestinal wall. Although the characteristic findings on plain abdominal radiograph, computed tomography (CT), and barium enema have been well described, the sonographic findings have not. We recently encountered a case of PCI in which abdominal sonography disclosed a unique finding. We were able to reproduce the finding experimentally and have coined it the "aurora sign".
肠壁囊样积气症（PCI）是一种罕见疾病，其特征为肠壁内出现多个大小各异的含气囊肿。尽管腹部平片、计算机断层扫描（CT）和钡灌肠的特征性表现已有详尽描述，但超声检查结果尚未见报道。我们最近遇到一例肠壁囊样积气症患者，腹部超声检查发现了一个独特的表现。我们通过实验重现了这一发现，并将其命名为“极光征”。
