ABSTRACT
Objective:To observe and analysis the clinical presentations and high resolution computed tomography (HRCT) features of patients with eosinophilic granulomatosis with polyangiitis (EGPA), and to provide support for clinical diagnosis and treatment decision.Methods:Clinical characteristics, relevant laboratory data, HRCT features, treatment and prognosis of 15 clinically confirmed EGPA patients were analyzed retrospectively. Statistical Program for Social Sciences (SPSS) 21.0 software was used for statistical analysis of the data.Results:Among the 15 patients, there were 8 males and 7 females, with a midian age of 48. Four cases (27%) were misdiagnosed as refractory asthma for the first time. The most common clinical manifestation was paranasal sinus inflammation in 14 cases (93%), followed by cough and wheeze in 13 cases (87%). In the laboratory examination, eosinophilia was found in 13 cases (87%) and ANCA positive in 5 cases (39%). The common chest HRCT signs were: fiber stripes in 13 cases (87%), patch ground glass opacities in 12 cases (80%), interlobular septal thickening in 10 cases (67%), and nodules in 9 cases (60%). The five-factor score (FFS) was used to score the patients, and FFS were 5(33%) with score 0 and 6(40%) with score1. Finally, 12 patients (80%) were discharged after remission.Conclusion:The EGPA has a low incidence and no spefic clinical manifestations and chest HRCT features, so it hasto be diagnosed by combination of paranasal sinus examination, electromyography and laboratory tests.
