Insular ribbon sign – refers to loss of the normal insular cortex grey-white differentiation and is one of the earliest imaging sign of middle cerebral artery territory infarction. The insular cortex is located along the Sylvian fissure overlying the external capsule where a ‘ribbon’ of normal cortex should be appreciable (red arrows). In the setting of MCA infarction, cytotoxic oedema leads to hypoattenuation such that the normal insular ribbon is no longer visible (blue arrows).
Case on the left shows a very early infarct (within the first few hours) while the case on the right shows a more established infarct (greater than 4 hours old).

Golden S sign – a chest radiograph sign of right upper lobe collapse due to an obstructing central mass. The margin of the collapsed upper lobe forms a reverse S shape (blue line) as the peripheral lung collapses with a concave outline while the more central lung maintains a convex margin around the mass. The sign is highly suggestive of primary lung cancer and should prompt further investigation with CT.
