Predictive value of computed tomography for eosinophilic chronic rhinosinusitis with nasal polyps in different histopathologic criteria.

Clinical features such as bilateral nasal polyps, severe olfactory dysfunction, and comorbid asthma and allergic rhinitis, as well as radiological features on Computed tomography (CT) and laboratory findings like elevated peripheral blood eosinophils and serum total IgE(tIgE), all have certain indicative significance for T2 inflammation in CRSwNP. 4 Japan's JESREC scoring system ultimately incorporated 3 indicators: CT findings, bilateral nasal polyps, and peripheral blood eosinophil counts. 5 A study by Zhang Luo's team, which included multiple indicators such as CT, peripheral blood, fractional exhaled nitric
