A 6-year-old intact male guinea pig was presented for acute abdominal pain, anorexia, and absence of ambulation for 12 h. Radiographs revealed moderate gastric dilation and multifocal marked small intestinal gas dilation. Ultrasonography showed a focally dilated jejunal loop with abrupt narrowing and torsion, with a mesenteric vascular "whirl sign". The aborad jejunum was empty. Surgery revealed a focal mesenteric torsion with associated segmental jejunal torsion and consequent jejunal occlusion. A cardiopulmonary arrest occurred during the surgery. This is the first report of diagnostic imaging findings associated with mesenteric torsion in a guinea pig.
一只6岁未绝育雄性豚鼠因急性腹痛、厌食及无法行走12小时前来就诊。X光片显示中度胃扩张及多灶性明显小肠气体扩张。超声检查显示一段空肠局限性扩张，伴有突然变窄和扭转，出现肠系膜血管“漩涡征”。扭转部位远侧的空肠空虚。手术发现局部肠系膜扭转伴节段性空肠扭转及由此导致的空肠梗阻。手术过程中发生了心肺骤停。这是首例关于豚鼠肠系膜扭转相关诊断影像学表现的报告。
