title: Intradiploic epidermoid causing spontaneous extradural hematoma: case report.
abstract: OBJECTIVE
  A case of an intradiploic epidermoid tumor leading to spontaneous extradural hematoma is reported. Intradiploic epidermoids are not common intracranial tumors. This is the first reported case of intradiploic epidermoid presenting as a spontaneous extradural hematoma.
  
  
  METHODS
  The patient presented with sudden onset of headache and deterioration in the sensorium. A computed tomographic scan revealed a lesion causing erosion of both tables of the calvarium and a mixed intensity extradural hematoma.
  
  
  METHODS
  The patient underwent immediate operation, and evacuation of the hematoma and excision of the tumor were performed.
  
  
  CONCLUSIONS
  Intradiploic epidermoid tumors so rarely present with extradural hemorrhage that prophylactic removal cannot be recommended in all such cases. However, in view of the seriousness of the hemorrhage, prophylactic removal may be recommended, especially if the patient, such as a sportsman, child, or elderly person, is prone to injuries.
