Duret hemorrhage
Updates to Case Attributes
Duret haemorrhages are most commonly seen at ventral and paramedian aspects of the upper brainstem, involving medulla and pons.
In this case, head trauma resulted in subdural and intraventricular haemorrhage, raising intracranial pressure. There is subfalcine and uncal herniation. The connection between the sudden increase in intracranial pressure and the development of Duret haemorrhages has two main hypotheses:
arterial origin with compromise of the perforator arteries that arise from the basilar artery
venous origin
