    Exposición de un caso de un paciente sexo masculino de 74 años, que acude con dolor abdominal en flanco izquierdo como única sintomatología, donde luego de evaluación clínica se recomienda ecografía complementaria en la cual como hallazgo incidental se reporta  la presencia de masa renal localizada en polo inferior renal izquierdo, con abundante captación al flujo Doppler en su periferia,  por lo que se sugiere URO TC, como método complementario para caracterización, estatificación definitiva de imagen en donde por su comportamiento al medio de contraste y ausencia de invasión a estructuras vasculares y ganglionares se plantea el diagnóstico de Carcinoma renal cromófobo vs Oncocitoma renal.

    With high frequency, renal masses are incidentally identified by imaging methods, many of these are renal cell carcinomas, the objective of imaging studies is to differentiate a benign mass from a renal cell carcinoma, up to 20% of the cases. Indeterminate solid renal masses finally turn out to be benign with a higher incidence of benignity in small renal masses (less than 4cm), however in some cases it is not possible to differentiate them; there are radiological signs that incline the diagnosis towards malignancy or benignity, and significantly affect the diagnosis, characterization, staging, orientation of treatment (partial and radical nephrectomy, biopsy and tumor ablation) as well as subsequent evaluation.

    Presentation of a case of a 74-year-old male patient, who came with abdominal pain in the left flank as the only symptomatology, where after clinical evaluation, complementary ultrasound is recommended in which the presence of a renal mass located in the pole is reported as an incidental finding. lower left kidney, with abundant Doppler flow uptake in its periphery, for which UROTC is suggested, as a complementary method for characterization, definitive image staging where, due to its behavior to contrast medium and absence of invasion to vascular and lymph node structures, raises the diagnosis of chromophobe renal carcinoma vs renal oncocytoma.
