Peritoneal carcinomatosis by pineoblastoma secondary to ventriculoperitoneal shunt

ABSTRACT

The primitive neuroectodermal tumors (PNETs) produce metastases in the basicranial axis. Extracranialmetastases are infrequent and occur by disseminationthrough the cerebrospinal fluid (CSP). Sixtytwo cases of peritoneal carcinomatosis have beenreported to date as due to a ventriculo-peritonealshunt (VPS), four of them by pineoblastoma. Wepresent the case of a pineoblastoma showing thisextremely rare evolution and its response to platinumcompounds and taxanes. We reviewed the literature which relates to this neoplasm and its treatment (AU)
