Hypertrophic renal column is a physiologic variant of the renal column. The renal column (also known as Bertin’s column) is the part of the renal cortex that extends into the medulla between adjacent renal vertebrae, which is a normal structure of the kidney, and the anatomical variant here is called hypertrophy of the renal column when it protrudes and enlarges and becomes embedded in the renal sinus. Embryologically, the renal column develops from the fusion of the renal lobes. Ultrasound shows that the renal cortex and medulla are hypoechoic, while the medulla is less echogenic than the cortex, and the collecting system is a hyperechoic area with a rough border surrounded by renal parenchyma. Hypertrophy of the renal column usually has no effect on the patient. The renal column is the cortical structure inserted into the renal vertebrae, which contains the renal corpuscles and tubules, as well as a blood vessel, which is often referred to as the interlobar artery. It is usually benign and does not affect the patient’s quality of life, and regular follow-up is sufficient.
