Insular ribbon sign - refers to loss of the normal insular cortex grey-white differentiation and is one of the earliest imaging signs 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).

Subependymal giant cell astrocytomas (SEGA) are benign tumours, seen almost exclusively in tuberous sclerosis (TS).   The foramen of Monro is the classic location, and the tumour arises when a subependymal nodule transforms into SGCA over a period of time.  http://radiopaedia.org/articles/subependymal-giant-cell-astrocytoma

Cerebral venous thrombosis (CVT) refers to occlusion of venous channels in the cranial cavity, including dural venous thrombosis, cortical vein thrombosis and deep cerebral vein thrombosis.   Non-contrast CT, when not associated with venous haemorrhage or infarction can be a subtle finding, relying on hyperdensity of the sinus being identified. Thrombus can appear as a hyperdense vein or sinus for the first 7-14 days; this is an accurate sign when present.  http://radiopaedia.org/articles/ce
