GENERAL HISTOLOGY

Detailed explanation-1: -Hypertrophic column of Bertin usually appears as a mass that extends towards renal sinus radiologically and an inexperienced radiologist could report it as a tumoural lesion. Sometimes it can show atypical characteristics, therefore CT or MRI might be needed for clarifying the diagnosis [4].

Detailed explanation-2: -The outer cortex and the inner medulla are the two regions of the kidney. Conical masses can be seen in the medulla. The term “medullary pyramids” refers to this. Between the renal pyramids is a medullary extension of the renal cortex called the column of Bertini, also referred to as the renal column.

Detailed explanation-3: -A hypertrophied column of Bertin is one of the congenital causes of renal pseudo tumor. The columns of Bertin are normal structures seen in the renal cortical tissue. In 1744, French anatomist Exupere Joseph Bertin explained that the renal cortex extended in radial fashion surrounding the renal pyramids.
