We report the case of a calcified lesion of the urinary bladder wall, in a 5-year-old child, asymptomatic. Calcifications in urinary bladder are not infrequent. In pediatric age and in adults the most common causes are calculi, chronic inflammation and irritation, schistosomiasis, tuberculosis and primary carcinoma of the bladder. The differential diagnosis should include other rare conditions, that can lead to urinary bladder calcification: pediatric benign and malignant tumors (rhabdomyosarcoma, hemangioma, inflammatory pseudotumor, leiomyoma, pheocromocytoma, transitional cell papilloma), dermoid cyst, urachus cyst’s, carcinoma of the urachus, alkaline encrusting cystitis, cyclophosphamide-induced cystitis, radiation cystitis and Prune-Belly’s syndrome. We report the case of a 5-years old boy followed at the Department of Translational Medicine-Section of Pediatrics, Federico II University, Naples, for hypertransaminasemia and recurrent respiratory infections. An ultrasound examination of the abdomen incidentally found the presence of a hyperechoic area of 5 mm in the urinary bladder, with “twinkling sign” at the Color-Doppler, suggestive of calcific nature. A consultation with a pediatric surgeon recommended a cystoscopic exeresis of the lesion. In February 2018, the exeresis was performed and the lesion was investigated with histological examination that showed normal urothelium with microcalcifications in the lamina propria of the bladder wall.
