Typical Ultrasound and Computed Tomography Features of the Perirenal Lymphoma
Abstract
Three cases of the perirenal lymphoma are presented. Tumor was seen as an encompassing lesion above the kidney in all cases. It appeared as a hypoechoic lesion during the ultrasound examination and hyperdense during the computed tomography. Doppler examination revealed vessels in lesion. Computed tomography showed decreased contrast media accumulation within the lesion comparing with the renal parenchyma. Visualization of vessels penetrating the lesion from the renal parenchyma and contrast media accumulation allowed differentiating tumor from the perinephric hematoma, urinoma, and age related changes of perinephric fat. Yarmulke sign term was suggested to describe this symptom.
