Occipital infarct

Case contributed by Dr Craig Hacking

Presentation

Acute right homonymous hemianopia

Patient Data

Age: 80
Gender: Male
Modality: CT

Wedge shaped loss of grey-white matter differentiation within the left medial occipital lobe is in keeping with an acute left PCA infarct. No intracranial haemorrhage. No significant mass effect.

Periventricular white matter hypoattenuation is most likely in keeping with moderate chronic small vessel ischaemia. Ventricular size is normal. Basal cisterns are unremarkable.

Case Discussion

Good case of acute PCA infarct causing a typical visual defect for disruption of the optic pathway posterior to the thalami (ie homonymous hemianopia). Chronic microangiopathic changes in this case were due to a long history of vasculopathy and multiple CVA risk factors.
