Male, 58 years old, with Horner's syndrome, several cranial nerves, sensory, motor and ataxic abnormalities. High suspicion for posterior circulation stroke. No restricted diffusion is seen. No evidence of significant parenchymal edema or mass effect is detected. A few scattered small foci of white matter T2 hyperintensity are seen, a nonspecific finding. No evidence of intracranial hemorrhage or any abnormal extra-axial fluid collection. The ventricles are normal in size and morphology. No convincing abnormality is seen on the fat-suppressed T1-weighted images to suggest vascular dissection or intramural hematoma. Staphylomatous deformation of the globes is redemonstrated.
No evidence of acute ischemia or any other specific finding which would account for the patient's symptoms.
