Computed tomographic features of central descending transtentorial herniation--case report

Computed tomographic (CT) features of central descending transtentorial herniation (DTH) were identified in a patient who presented with subarachnoid hemorrhage. The main features were symmetrical deformity of the brainstem and downward displacement of the third ventricle. The authors believe these findings will contribute significantly to the establishment of CT diagnostic criteria for central DTH.
