Ultrasound is able to identify frontal bone osteomyelitis,[1] while computed tomography (CT) can evaluate bony erosion, and along with magnetic resonance imaging (MRI), can better appreciate the underlying cause and extent of possible intra-cranial extension/involvement.

[2][3] 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.

[citation needed] 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.

[citation needed] The patient requires admission for intravenous anti-microbial treatment.
