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 ...

Restless legs syndrome (RLS) is the third most common reported sleep disorder, and one of the most common causes of severe insomnia. Including its mild form, this irritating disorder affects between 10 and 15 percent of the population. Although its classified separately as a movement disorder  its important to note that all sleep related movement disorders are technically parasomnias. Together they comprise the movement and behavioral disorders related to sleep. The way people describe their symptoms is often imprecise and can vary considerably, but the common denominator is an unpleasant sensation in the legs. Sufferers may say they feel a "creepy, crawly" sensation in their legs when they trying to sleep or when they're just resting quietly. Or they describe extreme discomfort, pain, pulling, searing, boring, or deep itching sensations down the legs. Some patients have even described this sensation as 'electric ants' or bugs running up and down the legs.

Restless Legs Syndrome The term restless legs syndrome (RLS) was used initially in the mid-1940s by Swedish neurologist Karl A. Ekbom to describe a disorder characterized by sensory symptoms and motor disturbances of the limbs, mainly during rest. However, early descriptions date back to the 17th century. It is recognized now as a neurologic movement disorder of the limbs, often associated with a sleep complaint. Patients with RLS have a characteristic difficulty in trying to depict their symptoms; they may report sensations such as an almost irresistible urge to move the legs, which are not painful but are distinctly bothersome; this can lead to significant physical and emotional disability. The sensations usually are worse during inactivity and often interfere with sleep, leading to walking discomfort, chronic sleep deprivation, and stress. Once correctly diagnosed, RLS can usually be treated effectively by relieving symptoms; in some secondary cases, it can even be cured. Path
