Toothache as a Warning Sign of Subarachnoid Hemorrhage Postmortem Findings

The symptoms of sudden severe headache and/or diminished consciousness characterize the onset of aneurysmal subarachnoid hemorrhage (SAH). However, several studies have suggested that some patients show an atypical presentation at the onset: symptoms lacking sudden headache and diminished consciousness. These atypical symptoms can easily lead to misdiagnosis. This paper reported the death cases of acute aneurysmal subarachnoid hemorrhage with toothache as the first symptom, hoping to provide clinical evidence for the general public doctors to reduce the misdiagnosis and delayed diagnosis of SAH, improve the identification ability of SAH, and prevent such death events from happening again.
