Abstract:
Unique radiologic features of Ask-Upmark kidney were reported. A contrast-enhanced computed tomography showed lobulated cortical thinning. Renal dimercaptosuccinic acid scan revealed isolated circular accumulations mimicking accessory kidneys. Our case indicates that the pathogenesis of this condition is most likely related to developmental anomalies.
