Ectopical kidney tissue in the left auricle of a rat.
A case of a 3 months old rat with ectopic renal tissue within the heart was described. The renal tissue consisted of well developed parts of the kidney cortex like glomerula and tubuli contorti. All parts of the kidney medulla such as excretory tubules and kidney pelvis were missing. It is believed that the ectopic kidney tissue developed from scattering of metanephric tissue. A physiological function of the intracardial renal tissue can be excluded.
