There is a case reported in the literature (3) of an acute renal thrombosis in which CT showed a hyperdense mass on non-contrast scan with a little enhancement after intravenous contrast material administration, findings that also led to nephrectomy of the affected kidney. The high attenuation of the lesion was presumably due to the recent formation of the thrombus. In our case, however, the lesion was seen as a low attenuating mass on the contrast-enhanced CT scan, which correlated with the old thrombosis seen on pathological examination.
In conclusion, we report a case of renal sinus venous thrombosis resembling a neoplasm on the ultrasound, intravenous urography and contrast-enhanced CT studies, which resulted in nephrectomy. Thus, although this is an uncommon condition, it should be considered in the differential diagnosis of a solid renal sinus lesion, especially when urine cytology is negative for malignant cells.
