Recurrent Pneumocephalus due to over Draining Thecoperitoneal Shunt in a Patient with Multiple Skull base Defects
摘要
We report a case of recurrence pneumocephalus in a 42-year-old man who underwent transnasal CSF leak repair for left lateral sphenoid meningocele, with thecoperitoneal(TP) shunt. The pneumocephalus was attributed to negative intracranial pressure created by an over draining shunt in the presence of multiple skull base defects.
