Cystic neuroblastoma (CN) is an extremely rare entity, although neuroblastoma is the most common solid tumor in infants. The radiologic diagnosis of CN is very difficult because of both the rarity and minimum solid component of the lesion. We describe herein the case of a 2-month-old girl presenting with dysuria because of a large presacral mass. Imaging studies including ultrasonography, computed tomography, and magnetic resonance imaging demonstrated a large septated cystic tumor mimicking a cystic sacrococcygeal teratoma, which commonly occurs in the presacral region. The tumor was finally diagnosed as CN after surgical resection. This is the second case report of presacral CN in the English literature. Cystic neuroblastoma should be considered in the differential diagnosis of presacral cystic tumors in infants.

The objective of this case report is to present a rare bladder tumour in a young patient 25 years after the treatment with cyclophosphamide because of a neuroblastoma of the right eye. The first symptom of the tumour was macroscopic haematuria with dysuria and pollakiuria. The final diagnosis was dictaminated by the pathologist and the best treatment option was radical cystoprostatectomy. Leiomyosarcoma was presented in a 26-year-old patient like the third different tumour, the second was an esphenoidal meningioma. At the 8th year of follow-up after the radical surgery, the patient is free of bladder disease. Bladder leiomyosarcoma is a rare tumour of the bladder and its early diagnosis and treatment are mandatory for best prognosis.

Paraganglioma of the urinary bladder is an uncommon clinical entity. Neuroblastoma of the urinary bladder is another rare tumor with only 7 reported cases, all in children. This report presents the case of a composite paraganglioma and neuroblastoma in a 45 year-old male who presented with dysuria and flank pain. On the computerized tomography scan, the bladder wall overlying the tumor was smooth and the mass had a large exophytic component. The initial diagnosis was paraganglioma on transurethral resection. Following partial cystectomy and bilateral pelvic lymph node dissection, pathology confirmed a composite tumor consisting of paraganglioma and neuroblastoma. To our knowledge, this is the first report of such a composite tumor involving the bladder.
