We report a case of tumour-related hydrocephalus in a child treated with a ventriculo-peritoneal shunt which subsequently became infected with gram negative bacteria (Escherichia coli). After successful treatment of the infection the patient became shunt independent and has remained so for over 2 years. Gram negative ventriculitis is associated with diminished cerebro-spinal fluid production and we discuss the literature to date regarding this phenomenon.
