[Pseudotumor of the left epigastrium].

The authors describe the case of a patient with an accessory spleen located between the spleen and upper pole of the left kidney. A repeated sonographic examination suggested a suspicion for a kidney tumour, shape anomaly of the spleen, accessory spleen or kidney, but did not exclude even benign tumour in retroperitoneum. Computer tomography proved a formation between the upper pole of the kidney and the spleen, whose density characteristic after a rapid intravenous injection of 60% Verografin at the amount of 1 ml per kg body weight was the same as that of the spleen. Only angiographic examination revealed that the case is an accessory spleen and not a tumour.
