Nontraumatic subarachnoid hemorrhage, unspecified [I60.9], Reason for Study: ^Reason: evaluate structure, any infectious concerns? History: Infant with subarachnoid bleed. Brain MRIMultifocal symmetric bilateral posterior temporal, parietal and occipital lobe as well as splenium of bilateral corpus callosum restricted diffusion lesions without evidence of hemorrhagic conversion indicating acute ischemic infarction.There are, however, focal susceptibility artifacts on bilateral lateral ventricles occipital horns indicating intraventricular hemorrhages which is unchanged since prior head CT scan.The ventricles, sulci and cisterns are symmetric.There is no evidence of abnormal enhancement.The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.
1. Bilateral symmetric acute ischemic infarctions involving parietal, posterior temporal, and occipital lobes as well as splenium of bilateral corpus callosum indicating acute ischemic infarctions without evidence of hemorrhagic conversion.2. Intraventricular hemorrhage.3. Normal brain MRA
