Ultrasonic diagnosis and clinical analysis of eosinophilic cystitis in children / 中华实用儿科临床杂志

ABSTRACT

Objective To explore the ultrasound imaging and the clinical analysis of eosinophilic cystitis in children and to improve the understanding of this very rare clinical disease.Methods The ultrasound imaging of 9 patients who were diagnosed as eosinophilic cystitis in Nanjing Children's Hospital Affiliated to Nanjing Medical University from Jul.2007 to May 2013 were analyzed retrospectively,and the relevant literatures were reviewed.Results The ultrasound imaging of the 9 patients were described as follows4 cases showed a diffuse thickening bladder wall,2 cases showed a localized mass-like thickening bladder wall,and 3 cases showed a markedly thickening anterior bladder wall and bilateral bladder wall.Laboratory studies showed that all the patients were presented with eosinophilia.Six patients underwent cystoscopy that showed an erythematous,and velvety appearance of the bladder mucosa.Histopathology disclosed a bladder mucosal tissue with dense interstitial eosinophilic infiltration consistent with eosinophilic cystitis.Three patients had clinical resolution under the treatment of anti-infections and urine alkalinization.Other 6 patients received prednisone at 0.5-1.0 mg/kg and an antihistamine treatment.Prednisone was eventually tapered off after 2-week reemission.Regular follow-up by urinary bladder ultrasound and urine routine did not show any disease recurrence in 9 children.Conclusions The combination of bladder wall thickening and peripheral eosinophilia may suggest the likely diagnosis of eosinophilic cystitis.Cystoscopy with bladder biopsy is the most important step in the diagnosis of eosinophilic cystitis.Anti-histamines and corticosteroids can be used as the primary management and have good results.
