ABSTRACT

Diagnosis: Posterior Cerebral Artery Infarction (left)

History: 56 y/o WM with four day history of right eye visual problems, short-term memory loss, confusion, and headache.

Findings: Initial CT scan reveals hypodensities in temporal and occipital lobes highly suggestive of infarction in the left PCA distribution. MRI coronal FLAIR and axial diffusion weighted imaging show high signal intensity in similar distribution- consistent with infarction. Of note, ADC mapping images were not obtained. MRA images show abrupt truncation at the origin of the left PCA, essentially affecting all brain parenchyma supplied by the left PCA. Please refer to the vascular map of PCA distribution attached.

Ddx: infarct mass lesion with surrounding edema contusion resolving hematoma focal infection with encephalitis

Exam: Systolic blood pressures were above 200 mmHg. The "right visual problem" was actually a bilateral field cut (right homonymous hemianopsia).

No MeSH data available.


Posterior Cerebral Artery in blue.  Most of the territory is the occipital lobe, but it also supplies the posterior/inferior temporal lobe and thalamus.
