Traumatic Intratumoral Hemorrhage Secondary to Ventriculoperitoneal Shunt
We report a case of a 14-month-old boy with a primary intraventricular oligodendroglioma and obstructive hydrocephalus. The child underwent a bilateral ventriculoperitoneal shunt and developed a massive and fatal intratumoral hemorrhage initiated by a mild traumatism when introducing the left ventricular catheter. Reviewing the literature, we found 9 cases of intratumoral bleeding after ventricular decompression: 7 (78%) cases after a V-P shunt and 2 (22%) cases after external ventricular drainage. The tumor was located in the posterior fossa in 6 (67%) cases and in the supratentorial region in 3 (33%) cases. The hemorrhage was fatal in 7 (78%) cases (Table). To our knowledge this is the first report in the literature of such a complication during a shunting procedure for obstructive hydrocephalus of tumoral origin. The existence of such unusual and fatal complication should be kept in mind when weighing the possible benefits of the “preoperative” shunting procedure against its possible hazards.
