Coiling and migration of peritoneal catheter into the breast: a very rare complication of ventriculoperitoneal shunt.

Upward migration of distal catheter of a ventriculoperitoneal shunt with coiling is very rare. Pseudocyst and galactorrhea are known breast-related complications. Here, we report a 13-year-old girl, known case of myelomeningocele and shunted hydrocephalus, who presented with right breast pseudocyst due to distal tube migration and coiling of the catheter. Plain radiography was not diagnostic because of severe levoscoliosis, but chest computed tomography scan was confirmatory of shunt coiling lateral to the breast. The possible mechanisms causing this uncommon complication are described.
