Presentation
Foreign body coming out of anus ?guide wire ?cause ?abdominal injury?
Patient Data
The V-P shunt tube lie in the peritoneal cavity- including the ventricular catheter, the valve and proximal portion of the distal peritoneal catheter. The valve is positioned adjacent to the distal ileum, just proximal to the ileocecal junction. The peritoneal catheter beyond the valve penetrates the sigmoid colon at the pelvic inlet exits through the rectum.
No evidence for free gas, free fluid, hemorrhage or collection in the abdomen or pelvis.
The solid organs are unremarkable.
Lungs clear. No mediastinal abnormality.
Suprapubic catheter.
Retracted VP shunt with the tip in the anorectum.
No V-P shunt on the CT head sequences.
Severe biventricular hydrocephalus
The brainstem and cerebellum arenormal in appearances on this examination.
Multiple bilateral fronto-parietal burr holes.
Case Discussion
A fascinating case of a migrated ventriculoperitoneal shunt with colonic perforation resulting in a presentation with a per rectal foreign body.
