This is the DDx for a paranasal sinus lesion ..... i think also taken from the case review series .... 

How many times a radiologist would see a lesion in the PNS during a routine brain CT and tend to report it as sinusitis .... It would be helpful if you storm your brain and think about other differentials ... each one of these has a different appearance than the other ....

The violet branch has been added by myself during studying of other diseases that I found it would be helpful to remember them during thinking about the DDx of a PNS mass ...

Stroke

Hemorrhage is most easily detected with CT, but it can also be visualized with gradient echo MR-sequences.

Hemorrhagic infarcts

Hemorrhagic infarcts

15% of MCA infarcts are initially hemorrhagic.

Dense MCA sign

Dense MCA sign

This is a result of thrombus or embolus in the MCA.
On the left a patient with a dense MCA sign.
On CT-angiography occlusion of the MCA is visible.

Insular Ribbon sign

Insular Ribbon sign

This refers to hypodensity and swelling of the insular cortex.
It is a very indicative and subtle early CT-sign of infarction in the territory of the middle cerebral artery.
This region is very sensitive to ischemia because it is the furthest removed from collateral flow.
It has to be differentiated from herpes encephalitis.
