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 […]

Short story of a complex renal cyst
