Checklist for interpreting kidney ultrasound
In our experience, checklists help novice users to systematically interpret the sonographic findings and reduce errors. So, I made SECONDS checklist for interpretation of nephrologist-performed renal ultrasound. Simply, it prompts […]
Renal angiomyolipoma
Here is a nice example of solitary renal angiomyolipoma (AML). Well-circumscribed hyperechoic lesion in the right kidney with echotexture similar to that of adjacent sinus fat. As discussed before, ultrasound […]
Parapelvic Cyst
A patient with a history of chronic kidney disease and nephrolithiasis is seen in the clinic for follow up. Last available serum creatinine is relatively stable compared to baseline. Resident […]
Pelvic Kidney
A middle-aged patient was seen in the nephrology clinic for evaluation of chronic kidney disease. No prior imaging was available. Patient was asymptomatic and there was no significant renal-related history […]
Two young patients with increased renal cortical echogenicity
We previously discussed that not all increased cortical echogenicity is chronic kidney disease (CKD). Here are two more illustrative cases. A young woman with a history of systemic lupus nephritis […]
Short story of a complex renal cyst
We have previously discussed about distinguishing between autosomal dominant polycystic kidney disease and acquired cystic kidney disease (ACKD). Chronic kidney disease (particularly dialysis-requiring) is frequently associated with the development of […]
A curious case of a large renal cyst
Here is an image of the right kidney obtained from an end-stage kidney disease patient. At first glance, it appears as expected: thin parenchyma, prominent peri-renal fat as you would […]
Renal allograft and ascites
While evaluating a transplanted kidney, we should pay particular attention to the surgical anatomy, presence of ureteral stent, and perinephric collections in addition to ruling out hydronephrosis. Below are examples […]
Renal infarction
These images were obtained from a patient with no known co-morbidities, who presented with acute right flank pain. There was no history of fever, hematuria, or other symptoms suggestive of […]
