title: Traumatic leptomeningeal cyst in a 24-year-old man: case report.
abstract: OBJECTIVE
  Traumatic leptomeningeal cysts represent a rare complication of a childhood cranial fracture, and occur in only 0.05 to 0.6% of all cranial fractures. In adults, clinical manifestations of a childhood trauma are very rare and usually appear in the form of nontender, nonpulsatile, subcutaneous mass, accompanied by a progressive neurological deficit and seizures, as shown in our case.
  
  
  METHODS
  We present the case of a 24-year-old man with seizures caused by a traumatic leptomeningeal cyst resulting from the head injury he suffered at the age of 9 months.
  
  
  METHODS
  Right-sided craniotomy was performed with consequent microsurgical removal of the leptomeningeal cyst. The dura was reconstructed in a watertight manner and a cranioplasty was performed with Palacos (Howmedica International, Limerick, Ireland).
  
  
  CONCLUSIONS
  It is important to consider traumatic leptomeningeal cysts when treating adult patients with erosive bone lesions who have a history of head trauma.
