What is polypoid opacification?
Polypoid lesions were defined as homogenous round opacities with distinct demarcating boundaries at the base (Fig. 2) while partial opacification was defined as at least one-third of the maxillary sinus being opacified without clear distinct boundaries (Fig. 3).
What is maxillary opacification?
Unilateral maxillary sinus opacification is a rela- tively common finding on radiographic studies of the para- nasal sinuses. There are many disease processes that can lead to solitary maxillary sinus opacification.
What does completely Opacified mean?
By definition a completely opacified, nonenhancing and mucus-filled expanded sinus, a mucocele is the most common expansile mass of a paranasal sinus (Figure 3). The frontal sinuses are most frequently affected (60-65%), followed by the ethmoid (20-30%), maxillary (10%) and sphenoid (2-3%).
What is Pansinus disease?
Pansinusitis is when all of the sinuses in the head become infected or inflamed. Usually, a sinus infection, or sinusitis, affects only one or two sinus groups. Pansinusitis may feel like a severe sinus infection but often clears up over time without treatment.
How do you treat polypoid mucosal thickening?
Conclusions: A combined short-term steroid therapy is highly effective in chronic polypoid rhinosinusitis, reducing the mucosal inflammation mainly in the large sinuses and reducing the incidence of symptoms significantly.
What is opacification in CT scan?
Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is.
What causes mucosal thickening?
Mucosal thickening is an inflammatory reaction with hyperplasia of the mucous lining of the maxillary sinus. This condition may result from harmful actions caused by trauma, infections, chemical agents, foreign body reaction, neoplasm, or airway conditions such as allergies, rhinitis, or asthma.
What is opacities in medical terms?
1 : the quality or state of a body that makes it impervious to the rays of light broadly : the relative capacity of matter to obstruct by absorption or reflection the transmission of radiant energy (as X-rays, infrared radiation, or sound) 2 : an opaque spot in a normally transparent structure (as the lens of the eye)
What does good opacification mean?
opacification – the process of becoming cloudy or opaque. natural action, natural process, action, activity – a process existing in or produced by nature (rather than by the intent of human beings); “the action of natural forces”; “volcanic activity”
Can chronic Pansinusitis be cured?
Pansinusitis may feel like a severe sinus infection but often clears up over time without treatment. However, some cases benefit from medical treatment, such as antibiotics or antifungal medications.
