ABSTRACT

Objective: To review the spectrum of ultrasound features of the renal cells cancer (RCC), and make a comparison with that reported in the literature.
Material and methods: The radiological file of patients with malign kidney tumor diagnosis in the last five years was reviewed, from which only whose diagnosis out of RCC corroborated by pathology were included. Besides, those whose ultrasounds didn’t comply with valid approaches were excluded, resulting a sample of 35 patients. Blind reading of the ultrasounds by two radiologists of the Institute was carried out.
Results: The results are similar to those reported in the literature as for the size of the lesion, to the diagnosis, echogenicity, presence of cystic/hemorrhagic degeneration, homogeneity/heterogeneity of the lesion, vascular pattern and calcifications.
Conclusions: The ultrasound is an economic and available method in the evaluation of RCC, and it continues being the study of first election, although it requires of experience and is operator-dependant.
