A patient is presented with widespread primary hydatid cysts in spinal-paraspinal locations, secondary to Echinococcus granulosus. An alternative mechanism to explain how the embryos gained access to the body is proposed: The embryos penetrated the intestinal muscle and may have directly entered into the inferior vena cava system through small venous connections between this system and portal circulation. Various conditions in daily life associated with Valsalva maneuver might have caused such an atypical passage of the embryos to the inferior caval system toward the retroperitoneum and spinal-paraspinal structures via lumber epidural venous plexuses.
一名患者因细粒棘球绦虫感染，在脊柱旁出现广泛的原发性包虫囊肿。本文提出了另一种解释胚胎如何进入人体的机制：胚胎穿透肠肌，并可能通过该系统与门静脉循环之间的小静脉连接直接进入下腔静脉系统。日常生活中与瓦尔萨尔瓦动作相关的各种情况，可能导致胚胎通过腰段硬膜外静脉丛非典型地进入下腔静脉系统，进而到达腹膜后和脊柱旁结构。
