Diagnosis is suspected clinically and is confirmed using cross sectional imaging of the sinuses and brain. The patient typically presents with a headache overlying the frontal sinuses and an associated forehead swelling. This is often preceded by a history of chronic rhinosinusitis. Plain X Rays can be used to demonstrate the location of this swelling, but the gold standard for diagnosis is a cross sectional CT scan of the sinuses and brain, aided by contrast to delineate the abscess itself.
