Recurrent pneumonia caused by transdiaphragmatic erosion of a ventriculoperitoneal shunt into the lung. Case report.

Author information

Department of Neurological Surgery, University of Wisconsin Hospital and Clinics, Madison 53792, USA.


To the best of the authors' knowledge, this report represents the first description of a ventriculoperitoneal (VP) shunt that migrated into the chest cavity where it caused recurrent pneumonias. This 15-year-old boy with a history of hydrocephalus treated with VP shunt therapy as an infant presented with a 2-year history of chronic coughing and recurrent pneumonia. A high-resolution chest computed tomography scan revealed a right lower lobe infiltration and evidence of migration of the peritoneal shunt tubing through the diaphragm into the lung parenchyma. The catheter was pulled back into the peritoneal cavity via a simple abdominal incision. The patient's long-term outcome was excellent, and there was complete cessation of the pneumonia.
