POST TRAUMATIC RETROCLIVAL EPIDURAL HEMATOMA IN A YOUNG ADULT

Introduction: Post-traumatic hematoma of the posterior fossa are rare and account for only 3% of all cerebral post-traumatic hematoma. They are common along the cerebellar convexity while retroclival location is rare with less than 30 cases reported in the literature. Most previously reported cases occurred in children, with only a small number of cases involving adult patients. Among these adult cases, only three had an associated fracture of the occipital condyle. Objectives:To report a rare case of epidural hematoma of retroclival seat in a young adult, review the pathophysiology and mechanisms of occurrence of these hematomas. Observation : We related the case of a young man of 25 years without disease history, with a following an AVP retroclival epidural hematoma associated with a fracture of the clivus extended to the right occipital condyle diagnosed on a brain CT conservatively treated. Conclusion:his type of hematoma is not exclusive to the pediatric population, and although there are few reported cases, it is possible that this entity is often under diagnosed and must involve the exploration of the CCO for eliminate ligament underlying instability.
