Objective
Some patients report the absence of a typical headache at the onset of subarachnoid
hemorrhage (SAH). We investigated the clinical backgrounds and characteristics of
patients with SAH without headache and compared the findings with those of patients
with SAH and headache.
Methods
We examined 224 patients retrospectively who underwent intracranial aneurysmal clipping.
Patient's characteristics, Fisher's computed tomography grade, situation at onset,
site of ruptured aneurysm, and symptoms were compared. Subjects were categorized into
two groups: headache group and nonheadache group.
Results
Eighteen patients (8.0%) did not present with headache. There were no significant
differences in terms of age, sex, Fisher's computed tomography grade, onset time,
or site of ruptured aneurysm.
Conclusions
The patients without headache have no specific clinical characteristics over patients
with common SAH.
