CSF hydrocele--unusual complication of V-P shunt.

CSF hydrocele as a complication of migration or extrusion of the peritoneal end of the V-P shunt has rarely been reported. Here the case of a 6 month old infant, born at 28 weeks gestational age, is reported. The baby was noted to have scrotal swelling, exacerbated by crying, two months after insertion of ventriculoperitoneal shunt. The hydrocele resolved following revision of the shunt. Possible pathophysiological causes are discussed.
