To study the pathologic basis of intestinal wall calcification caused by Schistosoma japonicum visualized with computed tomography (CT).
Twelve patients underwent CT of the abdomen to detect what pathologic examination proved to be schistosomiasis japonica. Eight intestinal specimens from five of the patients were subjected to radiography, and the pathologic and radiographic findings were correlated.
CT demonstrated curvilinear or nodular calcification in the colon in 11 patients, in the appendix in two, and in the distal ileum in one. In five patients, calcifications resembling tram tracks were found in the sigmoid colon. Pathologic examination of the specimens showed calcified eggs of S japonicum deposited more extensively in the submucosa and subserosa than in the muscularis propria, which led to the tram-track appearance.
The extensive curvilinear or tram-track calcification found in the colon in patients with schistosomiasis japonica is calcification of deposited eggs.
研究计算机断层扫描（CT）显示的日本血吸虫病所致肠壁钙化的病理基础。
12例患者接受腹部CT检查，以检测经病理检查证实为日本血吸虫病的情况。对其中5例患者的8份肠道标本进行了放射摄影，并将病理和放射学检查结果进行关联分析。
CT显示11例患者结肠出现曲线状或结节状钙化，2例阑尾出现钙化，1例回肠末端出现钙化。5例患者乙状结肠发现类似轨道状的钙化。标本的病理检查显示，日本血吸虫钙化卵在黏膜下层和浆膜下层的沉积比固有肌层更广泛，这导致了轨道状外观。
日本血吸虫病患者结肠中发现的广泛曲线状或轨道状钙化是沉积虫卵的钙化。
