A whirl sign on contrast-enhanced abdominal CT scan is indicative of intestine twisted around the mesenteric vessels, and is observed in cases of strangulated obstruction, signaling compromised intestinal circulation. In cases of intestinal volvulus, surgery is necessary to untwist the affected bowel, and resection is necessary if necrosis is present.
A 31-year-old Japanese man presented with acute lower abdominal pain and vomiting. Contrast-enhanced abdominal computed tomography (CT) revealed a 1440-degree clockwise torsion of superior mesenteric artery and a whirl sign. Intestinal volvulus in adulthood with a background of malrotation is extremely rare. Contrast-enhanced CT is effective for diagnosis.
腹部增强CT扫描上的漩涡征提示肠管围绕肠系膜血管扭转，见于绞窄性肠梗阻病例，表明肠循环受损。对于肠扭转病例，必须进行手术以解开受影响的肠管，如果出现坏死则需要进行切除。
一名31岁日本男性出现急性下腹痛和呕吐。腹部增强计算机断层扫描（CT）显示肠系膜上动脉顺时针扭转1440度及漩涡征。成年期伴有旋转不良背景的肠扭转极为罕见。增强CT对诊断有效。
