Abstract:
Objectives:To discuss the clinical and radiological features of IgG4-related rhinosinusitis.
Methods:In this retrospective research, the clinical data of 16 patients diagnosed with IgG4 related rhinosinusitis, who were enrolled in Beijing Tongren Hospital from November 2013 to September 2017, were collected. The clinical features, laboratory findings, radiological findings, histological features, treatment and prognosis were all summarized.
Results:There were 12 males and 4 females among 16 patients, and male-to-female ratio was 3︰1. The age was between 30 to 70 years old, with median age of 52 years old. The chief nasal complaints were nasal obstruction and hyposmia, complicated with proptosis and eyelid swelling in 11 patients (11/16). Serum IgG4 levels were elevated in all patients and the value was over 1.44 g/L, and one patient serum IgG4 level was up to 49.70 g/L. Computed tomography (CT) showed the mainly affected sinuses were bilateral ethmoid sinus and olfactory cleft. The classic feature of CT scans was thickening of the involved bilateral ethmoid sinus mucous membrane with ethmoid bone absorption, which was mainly at midline. Histological features were severe inflammation of the mucosal tissue with mass of neutrophils and plasma cell infiltration. All patients were treated by methylprednisolone combined with cyclophosphamide or methotrexate. Remission of symptoms was detected in all patients.
Conclusion:The clinical features of IgG4-related rhinosinusitis are often accompanied by orbital tissue involvement, elevated IgG4 serum concentration, associated sinus imaging changes, and sensitive glucocorticoid and immunosuppressive therapy.
