[Pseudo tumours of the adrenals--errors in interpretation and their avoidance (author's transl)]

In 13 patients an adrenal tumor was suggested by non-invasive roentgenologic studies (scout films of the abdomen, intravenous urograms, tomograms). The lesions turned out to be misdiagnosed after patients had undergone arteriography. Variations of the spleen, superimpositions of the tail of the pancreas and fluid filled hollow viscus were found to be the reason for this adrenal 'pseudo-tumors'. The possibilities of diagnosing those 'lesions' without doing invasive studies are discussed.
