An elderly female is initially admitted with a visual deficient. During her hospital stay she develops balance problems.
Patient Data
Territorial area of low attenuation with sulcal effacement in the left occipital lobe. No internal hemorrhage.
5 days into admission new symptoms developed & the CT was repeated.
The previously identified left occipital lobe infarction is now more pronounced, due to maturation.
A new territorial area of low attenuation have developed in the inferomedial left cerebellar hemisphere.
New left thalamic infarct with hemorrhagic transformation.
Case Discussion
This case demonstrates a dual territory infarction, within less than a week. A posterior cerebral artery (PCA) territory infarct in the supratentorial brain, followed by a posterior inferior cerebellar artery (PICA) territory infarct in the infratentorial brain as well as a left thalamic infarct.
These infarcts (ischemic stroke) were embolic in nature.
