Overview
CT scan should be done immediately if mucormycosis is suspected because it can help in delineating the extent of the disease. In rhinocerebral disease, the lesions are isodense to muscle and bone with a rim of soft tissue thickness around the paranasal sinuses if there is sinus involvement. There may be air fluid levels or complete sinus opacification. The reverse halo sign is an important radiographic finding on CT scan which indicates vascular invasion.
CT scan Findings
CT scan in rhinocerebral mucormycosis may demonstrate:[1]
- Isodense (to muscle and bone) lesions
- A rim of soft-tissue thickness along the paranasal sinuses
- Complete sinus opacification, air-fluid levels
- Obliteration of the nasopharyngeal tissue planes can also occur
CT scan in pulmonary mucormycosis confirms the findings found on chest x-ray and may demonstrate:[2]
- Diffuse low attenuation
- Multiple air lucencies that suggest cavitation
- Pulmonary artery pseudoaneurysms
- Consolidation
- Reverse halo sign(groung glass opacity-GGO surrounded by consolidation) suggesting vascular and chest wall invasion
