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).

Butterfly glioma – name given to a high grade astrocytoma, usually a glioblastoma multiforme, which crosses the corpus callosum. The often symmetric projections extending out from the midline simulate butterfly wings. These tumors most frequently occur in the frontal lobes and like all high grade gliomas the prognosis is poor. Rarely cerebral metastasestumefactive demyelination, lymphoma or cerebral toxoplasmosis may mimic this appearance.

Bear’s paw sign -refers to a distinctive cross-sectional imaging appearance of the kidney in xanthogranulomatous pyelonephritis.  In this chronic granulomatous disease the kidney is progressively replaced by a mass of reactive tissue appearing like the pads of a bear’s paw. The disease is almost always incited by staghorn calculi as was the case for this patient.
