腹膜癌转移为发生于乳房、卵巢、胰腺、子宫、前列腺、结肠、肾脏的恶性肿瘤或黑色素瘤的常见并发症,可经淋巴道传播、直接浸润、腹水流动以及血行播散等途径。过去文献报告过很多腹膜癌转移的X 线征象,但很少述及其发生率。作者报告40例腹膜癌转移常见X 线征象的发生率,并提出一种新X 线征—结肠固定征。在40例中,24例(60%)X 线表现为阳性,50%的原发性肿瘤为卵巢或结肠癌。x 线所见有腹 Peritoneal cancer metastasis is a common complication of malignant tumors or melanomas that occur in the breast, ovary, pancreas, uterus, prostate, colon, and kidney. It can be transmitted through lymphatic channels, direct infiltration, ascites flow, and hematogenous dissemination. In the past, many X-ray signs of peritoneal metastasis have been reported in the literature, but their incidence has rarely been described. The authors report the incidence of common X-ray signs in 40 cases of peritoneal carcinoma metastases and proposed a new X-ray sign, the colon fixed sign. Of the 40 patients, 24 (60%) showed positive X-rays and 50% of primary tumors were ovarian or colon cancer. The x-rays have a belly
