INTERESTING CASES ARE BEST VIEWED ON A DESKTOP DEVICE

Patient presents with sudden onset visual disturbance. What's the diagnosis?

There is a very hyperdense p3 segment of the right posterior cerebral artery, suggestive of acute embolic disease here, with signs of an established infarct at the medial aspect of the right occipital lobe

Test Your Knowledge

1. A patient presents with sudden onset visual disturbance. Which vascular territory is most likely involved?

Sample answer. ACA infarcts typically affect medial frontal cortex and lower-limb motor function.

Sample answer. MCA infarcts affect face/arm sensorimotor function and language, not isolated visual disturbance.

Sample answer. The PCA supplies the occipital cortex, so PCA territory ischaemia is the classic cause of sudden visual loss.

Sample answer. Anterior choroidal lesions typically involve the posterior limb of the internal capsule.

2. What is the next most appropriate imaging step?

Sample answer. Non-contrast CT is the standard first-line study to exclude haemorrhage before considering thrombolysis.

Sample answer. Not relevant to acute visual disturbance.

Sample answer. Has no role in acute stroke evaluation.
