Abstract
We report a case of eosinophilic cystitis in a 7-year-old boy with a history of atopic symptoms, with focus on the radiological findings. He presented with hematuria and dysuria and ultrasonography (US) showed irregular bladder wall thickening resembling a bladder mass. CT urography did not characterize the lesion any further and showed no local or distant spread. Biopsies revealed eosinophilic cystitis, a benign inflammatory condition. We found that US characterized the lesion at least as well as CT and should be the first choice of imaging. When staging is considered before biopsy, MRI should be preferred to CT. There are no specific radiological signs of eosinophilic cystitis. On follow-up, US was a safe, cost-effective imaging modality, but findings should be interpreted in a clinical context. In a child with hematuria and a bladder mass, eosinophilic cystitis is a relevant but rare differential diagnosis, especially when there is a known atopic history.

Summary
The aim of this paper is to draw attention to the presenting symptoms and the radiologic evaluation of eosinophilic cystitis in childhood. Eosinophilic cystitis is an inflammatory condition characterized by eosinophilic infiltration of the bladder wall. It is rare amongst children with only 59 cases in the literature to date [1,2,3,4,5]. In a review of 54 cases, the mean age of presentation was 6.7 years, with an overweight of male cases [1]. A tumor-like presentation on imaging has been reported previously, and the condition requires thorough diagnostics to rule out malignant disease. We present a typical case of this atypical disease with focus on the radiological aspects of diagnosis and follow-up
