A 5-month-old boy with ultrasonography showing bilateral hydronephrosis, referred for renal scan. On 99mTc-L,L,ethylenedicysteine (99mTc-LLEC) renal scan, tracer blush in flow images in the region of urinary bladder was seen and tumor mass was suspected. Contrast-enhanced CT showed a soft tissue mass in sacrococcygeal region. Histopathological examination of biopsy tissue revealed malignant round cell tumor and immunohistochemistry consistent with neuroblastoma. 131I-MIBG scan revealed uptake in the pelvic mass with no distant metastasis.
