Cardiac arrest [427.5], Reason for Study: ^Reason: eval for anoxic brain injury History: s/p cardiac arrest No evidence of acute ischemic or hemorrhagic lesion on the scan.Multifocal patchy bilateral periventricular white matter high signal intensity on FLAIR imaging indicate nonspecific small vessel ischemic disease.There is a focal susceptibility artifacts on the left thalamus with encephalomalacia indicating prior hemorrhagic lesion with hemosiderin deposition.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. Opacifications on bilateral mastoid air cells.. Opacification of paranasal cyst sinuses including sphenoid sinus, ethmoid sinus, frontal sinus and bilateral maxillary sinuses.
1. No evidence of acute ischemic or hemorrhagic lesion on this scan.2. Non specific small vessel disease.3. Chronic hemorrhagic foci on the left thalamus.
