Why is the radiotracer localizing to the right paranasal sinuses?
Osseous remodeling secondary to chronic fungal sinusitis
Complete obstruction of the right frontal, ethmoidal, sphenoidal, and maxillary sinuses with heterogeneous hyperdense contents. Partial obstruction of the right nasal airways. Diffuse osseous remodeling of the right sinus walls. Moderate to intense uptake in the right superior and medial sphenoid sinus wall and right superior maxillary sinus wall, with mild uptake in the other sinus walls. Bowing of the nasal septum, medial maxillary sinus wall, and medial orbital wall, with possible areas of dehiscence or erosion.
Right greater than left mandibular uptake likely from recent dental procedure.
