Diagnosis: Cardiac arrest, cause unspecified Altered mental status, unspecifiedClinical question: basilar artery stenosis s/p PEA arrest and worsening neuro examSigns and Symptoms: unresponsive, blown pupil, no corneal reflex The CSF spaces are appropriate for the patient's stated age with no midline shift. Foci of diffusion restriction are present along the lateral aspect of the right middle cerebellar peduncle and the anterior aspect of the medulla bilaterally. This was also present on the prior exam. There are new patchy foci of diffusion restriction present along the peripheral and inferior aspect of the cerebellar hemispheres right more than left.A small infarction the left occipital lobe identified in 9/22/2015 exam is not readily identified on the current exam however because it is too small to identify in this location.Normal vascular flow voids are present in the distal carotid arteries, and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus. Flow voids of the distal vertebral arteries and the basilar artery are diminished.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells demonstrate minor opacities. The visualized portions of the orbits are intact.
1.New foci of infarction are present in the inferior aspects of the cerebellar hemispheres bilaterally which involve the right cerebellar hemisphere more than the left cerebellar hemisphere.2.There is redemonstration of lacunar infarcts in the pons and medulla.
