Nowadays, kidney carcinomas still represent the topical tissue. Despite the reported rate about 3% of the total number of malignant diseases, recently there is recorded a significant increase of the incidence of the disease. The absolute majority of them represent renal carcinomas, in the clinical practice it is necessary to consider also less frequent forms of renal tumours as e.g. angiomyolipomas (hemartomas). Renal angiomyolipoma is ranged to benign carcinomas, its incidence is reported 0,3 - 3% of explored renal carcinomas. The main diagnostic method is considered CT examination, which evaluates above all the presence of fat tissue, bloodvessels and smooth muscle. Some diagnostic algorhytmes consider CT diagnostic to be definite and if the tumour is not symptomatic, conservative approach is recommended.
The authors in their report deal with the evaluation of diagnostic benefit of CT examination a angiomyolipomas. They come out of their own experience of detection of 3 liposarcomas at the patients with originally described angiomyolipoma and by means of retrospective comparison they attempt to revise the original findings.
The authors conclude their evaluation stating that CT examination can not be considered definite and totally reliable, especially if unilateral tumour is larger than 4 cm. In those cases the surgical revision with the extent given by peroperational finding is indicated.
