Communicating hydrocephalus following total parenteral nutrition.

Communicating hydrocephalus secondary to cerebral venous outflow obstruction has been reported in a few patients several months following removal of a TPN catheter. We report the case of an infant who developed this sequal 4 mo after the catheter was removed. We illustrate the techniques used to delineate the type of hydrocephalus. A lumbo-peritoneal shunt was performed to alleviate the condition.
