Case Description: A 69-year-old woman who had undergone a lumboperitoneal (LP) shunt for communicative hydrocephalus following subarachnoid hemorrhage caused by a ruptured aneurysm was identified with malfunction of the LP shunt system by dementia and gait disturbance. Hydrocephalus was revealed on computed tomography (CT). Under a laparoscopy, the intraabdominal peritoneal catheter was observed to be obstructed by fibrous encapsulation covering it like a long white stocking. Although the fibrous encapsulating tissue was excised by laparoscopy forceps, a ventriculoperitoneal shunt device was replaced with a new peritoneal catheter. The histopathological diagnosis of the surgically resected encapsulating tissue was the fibrous tissue with a few inflammation cells and a layer of lining cells surrounding some part of it. In the immunohistochemical study, a layer of lining cells surrounding the fibrous tissue showed immunohistochemically positive staining for calretinin. Conclusion: The fibrous encapsulation would be formed by peritoneal reaction to a peritoneal catheter as a foreign body by these histopathological and immunohistochemical analyses.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/cbe65848-6dca-4bb1-91e3-c80683629586/featured/hero-1782420996264.png","publishDate":"2017-06-27T00:00:00.000Z","doi":"10.4103/sni.sni_420_16","categories":["Pediatric Neurosurgery","Case Report"],"fullTextUrl":"http://surgicalneurologyint.com/wp-content/uploads/2017/07/8495/SNI-8-132.pdf"}
