Most cases of atlas burst fracture do not require surgical stabilization, because they can be successfully treated with external immobilization. The authors present two cases of atlas burst fracture in which surgical stabilization was required after external immobilization. The first patient was a 50-year-old male and the second patient was a 34-year-old male. ⋯ However, lateral offset of the atlas on the axis increased and atlanto-axial instability became evident three months later in both patients. They underwent upper cervical arthrodesis with satisfactory results. The authors review surgical indication and its timing in patients with atlas burst fracture.

Review Case Reports
[A case of internal carotid-posterior communicating artery aneurysm presenting pure acute subdural hematoma].
The incidence of acute subdural hematoma (SDH) due to a ruptured intracranial aneurysm varies from 0.5% to 7.9% of all intracranial aneurysms. Pure acute SDH without subarachnoid hemorrhage (SAH) is rare. According to the literature, only 18 cases (including our case) of pure acute SDH identified by CT scan have been reported. ⋯ The aneurysm was successfully clipped. Postoperatively, her consciousness improved immediately. In this case, the pure acute SDH identified by CT was responsible for causing the direct hemorrhage into the subdural space via an adhesive lesion.
