Cardiac arrest, cause unspecified [I46.9] / Unspecified coma [R40.20], Reason for Study: ^Reason: prognostication after cardiac arrest History: absence of mental status There are multifocal symmetric diffusion restriction lesions on bilateral occipital lobe, parietal lobes and frontal lobes. There is also focal diffusion restriction on the left basal ganglia.There is focal susceptibility artifact on the left inferior medial aspect of temporal lobe (series 901, image 92). There is no associated surrounding edema. The differential diagnosis include focal hemorrhage, parenchymal calcification or an artifact.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. The paranasal sinuses and mastoid air cells are clear.
Symmetric acute ischemic infarctions involving bilateral frontal, parietal and occipital lobes which is consistent with global hypoxic injury.
