Growth within Ventriculoperitoneal Shunt Tube.

Cerebrospinal fluid (CSF) shunt failure is commonly associated with infection or mechanical obstruction of the shunt system. A 4-year-old male child who had undergone multiple shunt revisions at another hospital for congenital hydrocephalus and later for shunt obstruction, presented with exposed shunt at the supraclavicular region. Shunt revision was performed. The CSF culture showed no growth; however, the histopathological examination of shunt tube showed growth inside the lumen of silicone tube well away from the tip of ventriculoperitoneal shunt. The skin biopsy from the exposed site revealed foreign body giant cell granulomatous reaction. The patient was discharged on postoperative day 6 without any complications. At 3 months follow-up, the patient is doing well. A growth of within the shunt tube prompted us to think of how the hardware can get infected and may remain a source of constant infection.
