title: Remote supratentorial extradural hematoma following posterior fossa surgery.
abstract: BACKGROUND
  Posterior fossa tumors are associated frequently with hydrocephalus. Remote supratentorial hematoma after posterior fossa surgery is a rare but dreaded complication.
  
  
  CONCLUSIONS
  These hematomas can be intraparenchymal or extradural. The possible causes include sudden decompression of ventricular pressure in the supratentorial compartment, rupture of cortical veins in the sitting position, coagulopathy, hemodynamic fluctuations during surgery, and position-related ischemia. We report a large bifrontal extradural hematoma following posterior fossa surgery for a vermian medulloblastoma.
