Prior infarct. Rostral to caudal (A-D) non-contrast computed tomographic axial slices of the head performed 2 years prior to current admission demonstrates hypoattenuation and parenchymal volume loss in the right parasagittal occipital lobe compatible with an old posterior cerebral artery territory infarct, as well as acute infarct in the territory of the bilateral superior cerebellar arteries.

Haitian man with past medical history significant for hypertension, diabetes mellitus, seizure disorder, and prior cerebrovascular accident (CVA) (Figure 1) of unknown etiology with residual dysarthria and gait abnormality presented with worsening dry cough and dyspnea on exertion.
Acute ischemic infarct. Rostral to caudal (A-D) non-contrast computed tomographic axial slices of the head performed on this admission demonstrates loss of gray-white differentiation in the parasagittal left occipital lobe and sulcal effacement compatible with recent ischemia, as well as diffuse brainstem edema. Additional surrounding punctate foci of hyperattenuation suggest petechial hemorrhage.

The patient then underwent computed tomography (CT) of the head, which revealed infarcts within the parasagittal left occipital lobe and brainstem (Figure 2).
