This sagittal (from the side) CT reconstruction of the paranasal sinuses demonstrates a small osteoma (small rounded white density) in the anterior ethmoid sinus region. These osteoma are rounded foci of compact bone which can affect the sinuses when they obstruct normal drainage pathways. In this case there is no obstruction of the paranasal sinuses.
