Abstract/OtherAbstract:
Object Spontaneous intracranial hypotension (SIH) is a significant cause of new-onset daily persistent headache. A generalized connective tissue disorder also involving the intracranial arteries has been suspected in the population with SIH. Therefore, the authors reviewed angiographic studies for the presence of intracranial aneurysms in a group of patients with SIH. Methods Magnetic resonance angiography studies of the brain were performed in 93 patients with SIH (mean age 43 years, range 14-86 years) and in 291 controls (mean age 56 years, range 28-78 years). Results Intracranial aneurysms were detected in 8 (8.6%) of the 93 patients with SIH (95% CI 2.9%-14.3%). This incidence was higher than in the control population (3 (1.0%) of 291 (95% CI 0%-2.2%; p = 0.0007). In 7 patients the aneurysms were incidental, and in 1 patient SIH developed 5 weeks after an aneurysmal subarachnoid hemorrhage. Conclusions In this retrospective case-control study, the frequency of intracranial aneurysms among patients with SIH was significantly higher than in the control population.
