Congenital thoracic ectopic kidney is a very rare developmental anomaly and the rarest form of all ectopic kidneys. It is usually asymptomatic and discovered incidentally on a routine chest radiography. ⋯ We hereby discuss the features of congenital thoracic ectopic kidney and review the literature. Although it is extremely rare, thoracic ectopic kidney should be considered in differential diagnosis of a mass with a well demarcated superior margin in the lower part of the thorax, and renal scintigraphy must be performed even if CT and IVP results are normal.
