Case #2


Findings

  • Hypodensity with loss of gray-white differentiation in the right PCA territory, including the right occipital lobe and ventrolateral right thalamus


Diagnosis

  • Right PCA territory infarct

Sample Report

Hypodensity and loss of gray-white differentiation in the right PCA territory concerning for acute/early subacute ischemia. Hypodensity in the ventrolateral right thalamus represents age-indeterminate ischemia. MRI could further assess the extent of ischemia.

No mass effect or evidence of hemorrhagic transformation.


Discussion

  • Remember that the thalamus is supplied by the PCA.
