Fungal sinusitis or fungal rhinosinusitis is the inflammation of the lining mucosa of the paranasal sinuses due to a fungal infection. [1] [2] It occurs in people with reduced immunity. The maxillary sinus is the most commonly involved. Fungi responsible for fungal sinusitis are Aspergillus fumigatus (90%), Aspergillus flavus, and Aspergillus ...
For sinusitis lasting more than 12 weeks, a CT scan is recommended. [65] On a CT scan, acute sinus secretions have a radiodensity of 10 to 25 Hounsfield units (HU), but in a more chronic state they become more viscous, with a radiodensity of 30 to 60 HU. [67] Nasal endoscopy and clinical symptoms are also used to make a positive diagnosis. [28]
Mucormycosis, also known as black fungus, [3] [4] is a severe fungal infection [11] that comes under fulminant fungal sinusitis, [12] usually in people who are immunocompromised. [9] [13] It is curable only when diagnosed early. [12] Symptoms depend on where in the body the infection occurs.
CT scan can show the full extent of the polyp, which may not be fully appreciated with physical examination alone. Imaging is also required for planning surgical treatment. [7] On a CT scan, a nasal polyp generally has an attenuation of 10–18 Hounsfield units, which is similar to that of mucus. Nasal polyps may have calcification. [14]
Asthma exacerbations, aspergilloma, chronic pulmonary aspergillosis, cavitation, local emphysema, chronic or recurrent atelectasis, and honeycomb fibrosis. [2] Causes: Aspergillus exposure. Risk factors: Asthma or cystic fibrosis. [1] Diagnostic method: Chest X-rays, CT scans, blood tests, immunological tests, and sputum cultures. [2 ...
Special views focusing on the orbit of the eye may be taken to investigate concerns relating to the eye. [8] CT scans are used by physicians specializing in treating the eye (ophthalmologists) to detect foreign bodies (especially metallic objects), fractures, abscesses, cellulitis, sinusitis, bleeding within the skull (intracranial bleeding), proptosis, Graves disease changes in the eye, and ...
The 2025 report has also included new rankings for diets designed to help chronic conditions such as arthritis, diverticulitis, fatty liver disease and irritable bowel syndrome, or stages of life ...
3) The ability to obtain cultures at the time of lavage, when clinically warranted or indicated by CT-scan evidence. 4) Avoiding the need for exposure to radiation, as fluorescence is used in its stead. 5) Lack of interference in anatomy. Functional Endoscopic Sinus Surgery (FESS) is one of the newer modalities in treatment of Chronic Sinusitis ...
