Clinical question: subarachnoid hemorrhage. Signs and symptoms :subarachnoid hemorrhage. Nonenhanced head CT:Residual blood within the fourth ventricle with interval decrease since prior study.Interval decrease in the supratentorial subarachnoid hemorrhage. Extensive residual hemorrhage is still present.Hematoma in the interhemispheric fissure measuring 28.7-mm in transverse axis not significantly changed since prior study. There is effacement of all cortical sulci. There are one suspected areas of cortical low attenuation in the left frontal and parietal region concerning for air the onset of ischemic stroke. Follow-up with an MRI is recommended.Shunted lateral ventricles remain stable in size since prior study and no evidence of hydrocephalus. Residual blood within the lateral ventricles demonstrate no definitive interval change.
1.No evidence of new hemorrhage since prior study.2.Slight interval decrease in the amount of subarachnoid hemorrhage and blood within the fourth ventricle.3.Stable size of ventricular system and intraventricular hemorrhage in the lateral and third ventricle.4.Suspected areas of low attenuation of the cortex in the left hemisphere concerning for possible early onset of ischemic strokes. For further evaluation an MRI exam is recommended.
