Ventriculoperitoneal shunts were routinely used in the past in children with posterior fossa tumors and hydrocephalus. They can, however, cause a multitude of problems.
This report highlights a previously unencountered phenomenon of a pyogenic abscess forming within a posterior fossa ependymoma as a result of shunt infection. The shunt was exteriorized and the child treated with antibiotics before surgery was done. Only a partial excision of the tumor was possible, as the inflammatory response caused by the abscess had obliterated tissue planes.
过去，脑室腹腔分流术常用于患有后颅窝肿瘤和脑积水的儿童。然而，它可能会引发诸多问题。
本报告着重介绍了一种此前未遇到过的现象，即由于分流感染，在后颅窝室管膜瘤内形成了化脓性脓肿。在进行手术前，先将分流管外置，并使用抗生素对患儿进行治疗。由于脓肿引发的炎症反应使组织层面消失，所以只能对肿瘤进行部分切除。
