Acute obstruction of a patent processus vaginalis occurred in two boys, mimicking incarceration of an inguinal hernia. In fact, obstruction was caused by an intussusception of the processus vaginalis forming an intussuscipiens that occluded the hernia sac. This lesion, described previously in 1896 and in 1974, is one of the mechanisms by which an asymptomatic hernia or hydrocele becomes acutely symptomatic.
两名男孩出现了通畅的鞘状突急性梗阻，表现类似腹股沟疝嵌顿。实际上，梗阻是由鞘状突套叠形成套入部，阻塞疝囊所致。这种病变曾在1896年和1974年被描述过，是无症状疝或鞘膜积液突然出现症状的机制之一。
