title: Cerebrospinal fluid galactorrhea: a rare complication of ventriculoperitoneal shunting.
abstract: In this report we describe a 26-year-old woman who had an intra-abdominal pseudocyst located at the peritoneal catheter tip following ventriculo-peritoneal (VP) shunt implantation. Retrograde cerebrospinal fluid (CSF) flowed outside the catheter and communicated with the right breast lactiferous ductal system and leaked from the nipple orifice. CSF galactorrhea only occurs when the lactiferous duct is injured during VP shunt implantation, in combination with the formation of an intra-abdominal CSF pseudocyst prior to lactiferous duct healing. Leakage of CSF from the nipple orifice can be successfully treated by simply guiding the peritoneal catheter tip into the peritoneal cavity through a new laparotomy; that is, shunt revision is not always required.
