BACKGROUND:: The importance of isolated traumatic subarachnoid hemorrhage (SAH) in relation to functional outcome in patients with mild traumatic brain injury (TBI) has not been frequently studied. The aim of this study was to compare the impact of isolated SAH with normal computed tomographic (CT) scan on outcome of patients with mild TBI. METHODS:: This is a retrospective study of clinical records and CT scans of all patients with mild TBI (Glasgow Coma Scale score ≥13) evaluated from January 1, 2010, to March 15, 2010, at our institution. The patients were divided into 2 groups: isolated SAH and normal CT scan. The telephonic Glasgow Outcome Scale-Extended, Rivermead Post-Concussion Symptoms Questionnaire (RPCSQ), and Rivermead Head Injury Follow-up Questionnaire (RHFUQ) scores were used to assess outcome after 1 year of injury. Independent sample t test in SPSS was used to assess difference in outcome. RESULTS:: A total of 1149 patients with mild TBI were evaluated during study period. Among them, 34 (2.9%) patients had isolated SAH. Twenty-eight patients were male and 6 were female, with a mean age of 36.5 years. Subarachnoid hemorrhage was cortical in 19 (55.9%) patients, interhemispheric in 3 (8.8%) patients, Sylvian fissure in 2 (5.9%) patients, and basal cisternal in 1 (2.9%) patient. Nine (26.5%) patients had SAH at multiple locations. The mean RPCSQ and RHFUQ scores for patients with isolated SAH were 1.38 ± 2.40 and 1.11 ±3.305, respectively. The mean RPCSQ and RHFUQ scores for patients with normal CT scans were 0.40 ± 1.549 and 0.533 ± 1.59, respectively. There was no significant difference in the outcome scores between the SAH and the normal CT scan groups (RHFUQ, P = .45; RPCSQ, P = .248). CONCLUSION:: In our study sample of patients with mild TBI, there is no difference in outcome of patients with isolated SAH compared with those with normal CT scans 1 year after injury.
