209 Possible Causes for Sinus Opacification

  • Sinusitis

    Imaging revealed diffuse sinus opacification and a Le Fort type I complex fracture involving the maxilla, pterygoid plates, clivus, and right nasal bridge.[] Overall, the sinus opacification and mucosal thickening rates did not change significantly which suggested the operation did not pose patients at increased risk of sinusitis[] Image studies show complete opacification of the left frontal sinus, left sphenoid sinus, and the left maxillary sinus.[]

  • Nasal Polyp

  • Rhinocerebral Mucormycosis

    Complete sinus opacification, gas-fluid levels and obliteration of the nasopharyngeal tissue planes can also occur.[] opacification extending into the right orbit with compression of optic nerve [Figure 12] .[] […] level, thickening of the sinus mucosa, and full opacification.[]

  • Mucocele of the Sphenoid Sinus

    Sphenoid Sinus Mucocele Fig. 1: Axial unenhanced CT image shows opacification of the left sphenoid sinus due to a mass (arrow) causing slight expansion of the sinus.[] Computed tomography of the paranasal sinuses demonstrated complete opacification of the sphenoid sinus.[] […] radiographs: Sinus opacifications Air-fluid level Mass Fractures 21 Water view Best for maxillary sinuses and orbital rims Blow-out fractures 22 Caldwell view Best for frontal[]

  • Mucocele

    If obtained, they demonstrate opacification and expansion of the affected sinus.[] A, Coronal MR image showing abnormal opacification of the sphenoid sinus ( asterisk [*]).[] Paranasal sinus mucoceles (or mucocoeles) represent complete opacification of one or more paranasal sinuses by mucus, often associated with bony expansion due to obstruction[]

  • Mucocele of the Paranasal Sinus

    If obtained, they demonstrate opacification and expansion of the affected sinus.[] […] of the maxillary sinus and opacification of the ipsilateral ostium and infundibulum; the ostiomeatal unit pattern, with inflammation of the ipsilateral maxillary, frontal[] Complete or subtotal opacification of the involved sinus is not uncommon. Up to 41% demonstrated heterogenous opacification with calcifications ( Fig 7) .[]

  • Chronic Sinusitis

    The presence of opacification is not a good distinguisher from an acute sinus infection.[] […] signaling from the high protein content in the mucus) or low signaling of fungal concretions in sinus cavities on MRI.[] […] paradoxical middle turbinate (10%) agger nasi cells (10%) Haller cells (9%) CT A characteristic feature on CT sinuses is sclerotic thickened bone (hyperostosis) involving the sinus[]

  • Lethal Midline Granuloma

    Coronal (left) and axial (right) CT scans of the sinus reveal severe pansinusitis with abnormal nasopharyngeal thickening, right facial edema and right temporal bone opacification[]

  • Dacryocystitis

    […] to the orbit. 1 None of our cases had any evidence of sinus disease, and it is more likely that any sinus opacification seen is secondary to adjacent inflammation from the[] […] dacryocystitis or unrelated sinus disease.[] […] orbital involvement could have resulted from spread of infection from the lacrimal sac to the ethmoid sinus through the lamina papyracea, with subsequent extension from the sinus[]

  • Aspergilloma

    Diagnostic testing CT scans usually show sinus opacification, with or without discrete calcification or metallic densities surrounded by spiculated or linear areas of microcalcification[] Thickening of the walls of the involved sinus may be seen as may bone erosion or remodeling.[]
