“…11 In accordance with this, one report of renal infarction in which the patient presented with an acute onset of flank pain, the gray-scale sonography of the kidneys was normal, 12 while in two cases of subacute or chronic presentation, renal sonography demonstrated an echogenic wedge-shaped renal mass, without posterior shadowing. 13 In this case study, the infarct area changed from being poorly marginated and slightly hypoechoic at day 4 to having a clearly defined marginated appearance and being hypoechoic at day 11; the latter appearance did not change up to the last examination at day 104. We hypothesize that the histological changes seen in the experimental study were inhibited in this patient by immunosuppression putting an end to echogenicity changes.…”

This case study provides a report on a patient who had a segmental renal allograft infarction. The cause of this infarction within the segmental vessels was theorized to be due to prolonged warm ischemia within the organ donor. The area of infarction was visualized by the use of contrast-enhanced ultrasound (CEUS). This report raises the question as to whether routine sonographic imaging can demonstrated the sequence of infarction within a fresh renal allograft, as is routinely noted in native kidneys. This report highlights the importance of taking the segmental infarction into consideration when approaching the renal allograft recipient. CEUS could provide an important clinical application for the diagnosis of renal allograft infarctions and avoid more invasive procedures. Knowledge of the lack of sequence of sonographic changes in renal allograft infarction helps in assessing the function and outcomes of renal allograft recipients.

“…Similar peripheral, anterior, echogenic lesions can be seen in malrotated kidneys, in cross-fused renal ectopia, and in the case of an accessory renal hilus [2]. It is important that these normal variants be differentiated from pathologic entities, such as renal infarction, chronic pyelonephritis, or echogenic neoplasms [3][4][5]. The former two processes often are accompanied by focal cortical loss, single or multifocal.…”

“…Renal cortical lesions, which are more echogenic than the adjacent parenchyma on sonography and are of low density on CT, have been described in various benign and malignant conditions [1][2][3][4][5][6][7].…”
