Abstract

Abstract : Objective: This study aimed to evaluate the association between misdiagnosis of spontaneous intracranial hypotension (SIH) and subdural hematoma development. Background: Although SIH is more prevalent than expected and causes potentially life‐threatening complications including subdural hematoma (SDH), the association between misdiagnosis of SIH and SDH development is not yet evaluated. Methods: Retrospective observational study was conducted between January 1, 2005, and December 31, 2014. Adult patients with spontaneous intracranial hypotension (age ≥ 18 years) were enrolled. Results: Of the 128 patients with SIH, 111 (86.7%) were in no SDH group and 17 (13.3%) were in SDH group. Their clinical presentation did not show significant different between the two groups, except age, the days from symptom onset to correct diagnosis, and the number of misdiagnoses. Age (odds ratio [OR], 1.15; 95% confidence interval [CI], 1.07‐1.23) and the number of times SIH was misdiagnosed (OR, 1.82; 95% CI, 1.03‐3.21) were independent risk factors for the development of SDH in SIH patients by multivariate logistic analysis. The clinical outcomes, including length of hospital stay and revisit rate, were similar in the two groups. Conclusions: The number of times SIH was misdiagnosed was associated with the later development of SDH perhaps because of delay in correct diagnosis of SIH. Clinicians would prevent the later complication of SDH in SIH patients by increasing the awareness and a high index of suspicion of SIH.
