Altered mental status with periprocedural seizure-like activity. Evaluate for seizure, air embolus, or stroke. Image quality is significantly degraded by motion artifact. There is no evidence of large acute intracranial hemorrhage, or mass effect. There is slight increased signal of the posterior limb of the left internal capsule on the diffusion weighted imaging, but there is no corresponding increased T2 signal abnormality. Given extensive motion artifact, this is favored to be artifactual. There are scattered patchy areas of abnormal T2 hyperintensity within the periventricular and subcortical white matter. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
1.Significant motion artifact limits evaluation. No evidence of large acute intracranial hemorrhage or mass effect.2.Mild increased signal of the posterior limb of the left internal capsule on the diffusion weighted imaging, without corresponding increased T2 signal abnormality, is favored to be artifactual and related to extensive motion. Consider repeat of the diffusion weighted imaging when the patient is able.3.Scattered foci of abnormal T2 signal abnormality in the periventricular and subcortical white matter, which are nonspecific, but most consistent with moderate chronic small vessel ischemic changes.
